2 Introduction
Diving
Dive Warnings
WARNING
• The diving features of this device are for use by certified divers only. This device should not be used as a sole
dive computer. Failure to input the appropriate dive-related information into the device can lead to serious
personal injury or death.
• Do not exceed the maximum dive depth rating for the device (Specifications, page118).
• Make sure that you fully understand the use, displays, and limitations of your device. If you have questions
about this manual or the device, always resolve any discrepancies or confusion before diving with the device.
Always remember that you are responsible for your own safety.
• There is always a risk of decompression illness (DCI) for any dive profile even if you follow the dive plan
provided by the dive tables or a diving device. No procedure, diving device, or dive table will eliminate the
possibility of DCI or oxygen toxicity. An individual's physiological make up can vary from day to day. This
device cannot account for these variations. You are strongly advised to remain well within the limits provided
by this device to minimize the risk of DCI. You should consult a physician regarding your fitness before
diving.
• Always use backup instruments, including a depth gauge, submersible pressure gauge, and timer or watch.
You should have access to decompression tables when diving with this device.
• Perform pre-dive safety checks, such as checking proper device function and settings, display function,
battery level, tank pressure, and bubble checks to check hoses and connections for leaks.
• This device should not be shared between multiple users for diving purposes. Diver profiles are user specific,
and using another diver's profile can result in misleading information that could lead to injury or death.
• For safety reasons, you should never dive alone. Dive with a designated buddy, even if you have someone
monitoring your dive from the surface. You should also stay with others for an extended time after a dive,
because the potential onset of decompression illness (DCI) may be delayed or triggered by surface activities.
• Apnea diving requires appropriate training. Pool apnea diving carries many of the same risks as apnea diving
in open water. Never dive alone.
• This device is not intended for commercial or professional dive activities. It is for recreational purposes only.
Commercial or professional dive activities can expose the user to extreme depths or conditions that increase
the risk of DCI.
• Do not dive with a gas if you have not personally verified its contents and input the analyzed value to
the device. Failure to verify tank contents and input the appropriate gas values to the device will result in
incorrect dive planning information and could result in serious injury or death.
• Diving with more than one gas mixture presents a much greater risk than diving with a single gas mixture.
Mistakes related to the use of multiple gas mixtures may lead to serious injury or death.
• Always ensure a safe ascent. A rapid ascent increases the risk of DCI.
• Disabling the deco lockout feature on the device can result in an increased risk of DCI, which can result in
personal injury or death. Disable this feature at your own risk.
• Violating a required decompression stop may result in serious injury or death. Never ascend above the
displayed decompression stop depth.
• Always perform a safety stop between 3 and 5 meters (9.8 and 16.4 feet) for 3 minutes, even if no
decompression stop is required.
• For devices that support the dive readiness feature, the feature calculates dive readiness scores based on a
limited set of factors and does not measure whether or not it is safe for you to dive. It is the responsibility of
the diver to judge their own dive readiness and to plan and conduct a dive safely. Failure to do so could result
in an accident leading to serious personal injury or death.
Diving 3
Dive Modes
The Descent G2 device supports seven dive modes. Each dive mode has four phases: dive pre-check, surface
display, in-dive, and post-dive. During the pre-dive check, you can confirm the dive settings before you start
diving (Dive Setup, page5). The surface phase shows the data screens for the dive mode (Dive Data Screens,
page10). The in-dive phase shows data about the dive in progress, and other watch features, such as GPS, are
disabled (Going Diving, page14). During the post-dive review, you can view a summary of the completed dive
(Viewing the Dive Log Glance, page22).
Single-Gas: This mode allows you to dive with a single gas blend. You can set up to 11 additional gases as
backup gases.
Multi-Gas: This mode allows you to configure multiple gas blends and switch gases during your dive. You can
set the oxygen content from 5–100%. This mode supports one bottom gas, and up to 11 additional gases as
decompression or backup gases.
NOTE: Backup gases are not used in no-decompression limit (NDL) and time to surface (TTS)
decompression calculations until you activate them during a dive.
CCR: This mode for closed-circuit rebreather (CCR) diving allows you to configure two partial pressure of
oxygen (PO2) setpoints, closed-circuit (CC) diluent gases, and open-circuit (OC) decompression and backup
gases.
Gauge: This mode allows you to dive with basic bottom timer features.
NOTE: After diving in gauge mode, the device can only be used in gauge or apnea mode for 24 hours.
Apnea: This mode allows you to free dive with apnea-specific dive data. This mode has a higher data refresh
rate.
Apnea Hunt: This mode is similar to the Apnea dive mode, but tuned specifically for spearfishers. This mode
disables start and stop tones.
Pool Apnea: This mode allows you to perform a dynamic or static apnea dive in a pool with activity-specific dive
data.
Using the Pool Dive Mode
When the device is in pool dive mode, the tissue load and decompression lockout features function normally,
but dives are not saved to the dive log.
1 Hold LIGHT to view the controls menu.
2 Select .
The pool dive mode turns off automatically at midnight.
4 Diving
Dive Setup
You can customize the dive settings based on your needs. Not all settings are applicable for all dive modes. You
can also edit the settings before you start a dive.
Hold MENU, and select Dive Setup.
Gases: Sets the gas blends used in the gas dive modes (Setting Up Your Breathing Gases, page6). You can
have up to twelve gases for each gas dive mode.
Conservatism: Sets the level of conservatism for decompression calculations. Higher conservatism provides a
shorter bottom time and a longer ascent time. The Custom option sets a custom gradient factor.
NOTE: Make sure you understand gradient factors before entering a custom level of conservatism.
Auto Dive: Sets the type of dive activity that starts automatically when you begin your descent. You can use the
Snooze option to temporarily disable this feature.
Water Type: Sets the water type.
PO2: Sets the partial pressure of oxygen (PO2) thresholds, in bar, for the maximum operating depth (MOD),
decompression, warnings, and critical alerts (Setting PO2 Thresholds, page9).
Scuba Alerts: Sets custom alerts for gas dives (Custom Dive Alerts, page6).
Apnea Alerts: Sets custom alerts for apnea dives (Custom Dive Alerts, page6).
Display Settings: Customizes the data screens for each dive mode (Dive Data Screens, page10).
Safety Stop: Changes the safety stop duration.
Last Deco Stop: Sets the depth of the final decompression stop.
Apnea Discipline: Sets the discipline type for apnea diving.
End Dive Delay: Sets the length of time before the device ends and saves a dive after surfacing.
CCR Setpoints: Sets high and low PO2 setpoints for closed-circuit rebreather (CCR) dives (Setting CCR
Setpoints, page9).
Dive Shortcuts: Assigns button shortcuts for use during dives.
Advanced Settings: Customizes advanced dive mode settings (Dive Mode Advanced Settings, page5).
Dive Mode Advanced Settings
Hold MENU, and select Dive Setup > Advanced Settings.
Double Tap to Scroll: Enables a double-tap on the dive computer to scroll through the dive data screens. If you
notice accidental scrolling, you can use the Sensitivity option to adjust the responsiveness.
UP Key: Disables the UP button during dive activities to prevent inadvertent button presses.
Silent Diving: Disables all tones and vibrations for alerts during dive activities.
Heart Rate: Enables a heart rate monitor for dives. The Stored Strap Data option allows you to enable a chest
heart rate monitor, such as the HRM-Pro
™
series accessory, that stores heart rate data with the dive. You can
view chest heart rate monitor data in the Garmin Dive
™
app after you complete the dive.
Compass: Calibrates and set the north reference of the dive compass (Calibrating the Compass Manually,
page86).
No-Fly Time: Sets the no-fly countdown timer mode (No-Fly Time, page10).
Satellites: Sets the satellite system to use for dive entry and exit locations for each dive mode (Satellite Settings,
page57).
Units: Sets the distance, depth, temperature, and tank pressure units of measure for diving.
Deco Lockout: Disables the decompression lockout feature. This feature prevents single-gas, multi-gas, and
CCR dives for 24 hours if you violate a decompression ceiling for more than three minutes.
NOTE: You can still disable the decompression lockout feature after violating a decompression ceiling.

Dive Readiness
WARNING
The dive readiness feature calculates dive readiness scores based on a limited set of factors and does not
measure whether or not it is safe for you to dive. It is the responsibility of the diver to judge their own dive
readiness and to plan and conduct a dive safely. Failure to do so could result in an accident leading to serious
personal injury or death.
Your dive readiness is a score and a short message that can help you decide whether you are ready to dive. The
score is continuously calculated and updated throughout the day using these factors:
• Sleep score (last night)
• Recovery time
• Body battery
• Jet lag
• Dive history
• Sleep history (last 3 nights)
• Training status

Dive Terminology
Central nervous system (CNS): A measure of central nervous system oxygen toxicity caused by exposure to
increased partial pressure of oxygen (PO2) while diving.
Closed-circuit rebreather (CCR): A diving mode used for dives performed with a rebreather that recirculates
exhaled gas and removes carbon dioxide.
Maximum operating depth (MOD): The greatest depth at which a breathing gas can be used before the partial
pressure of oxygen (PO2) exceeds the safe limit.
No decompression limit (NDL): A dive that does not require decompression time while ascending to the
surface.
Oxygen toxicity units (OTU): A measure of pulmonary oxygen toxicity caused by exposure to increased partial
pressure of oxygen (PO2) while diving. One OTU is equivalent to breathing 100% oxygen at 1 ATM for 1
minute.
Partial pressure of oxygen (PO2): The pressure of the oxygen in the breathing gas, based on depth and oxygen
percentage.
Surface interval (SI): The amount of time that has elapsed since the completion of the last dive.
Time to surface (TTS): The estimated amount of time it will take to ascend to the surface, including
decompression stops.

Jumpmaster
WARNING
The jumpmaster feature is for use by experienced skydivers only. The jumpmaster feature should not be used
as a primary skydiving altimeter. Failure to input the appropriate jump related information can lead to serious
personal injury or death.
The jumpmaster feature follows military guidelines for calculating the high altitude release point (HARP). The
watch detects automatically when you have jumped to begin navigating toward the desired impact point (DIP)
using the barometer and electronic compass.
Jump Types
The jumpmaster feature allows you to set the jump type to one of three types: HAHO, HALO, or Static. The jump
type selected determines what additional setup information is required. For all jump types, drop altitudes and
opening altitudes are measured in feet above ground level (AGL).
HAHO: High Altitude High Opening. The jumpmaster jumps from a very high altitude and opens the parachute
at a high altitude. You must set a DIP and a drop altitude of at least 1,000 feet. The drop altitude is assumed
to be the same as the opening altitude. Common values for a drop altitude range from 12,000 to 24,000 feet
AGL.
HALO: High Altitude Low Opening. The jumpmaster jumps from a very high altitude and opens the parachute at
a low altitude. The required information is the same as the HAHO jump type, plus an opening altitude. The
opening altitude must not be greater than the drop altitude. Common values for an opening altitude range
from 2,000 to 6,000 feet AGL.
Static: The wind speed and direction are assumed to be constant for the duration of the jump. The drop altitude
must be at least 1,000 feet.
Entering Jump Information
1 Press START.
2 Select Jumpmaster.
3 Select a jump type (Jump Types, page45).
4 Complete one or more actions to enter your jump information:
• Select DIP to set a waypoint for the desired landing location.
• Select Drop Alt. to set the drop altitude AGL (in feet) when the jumpmaster exits the aircraft.
• Select Open Alt to set the open altitude AGL (in feet) when the jumpmaster opens the parachute.
• Select Forward Throw to set the horizontal distance traveled (in meters) due to aircraft speed.
• Select Crs. to HARP to set the direction traveled (in degrees) due to aircraft speed.
• Select Wind to set the wind speed (in knots) and direction (in degrees).
• Select Constant to fine-tune some information for the planned jump. Depending on the jump type, you
can select Percent Max., Safety Factor, K-Open, K-Freefall, or K-Static and enter additional information
(Constant Settings, page46).
• Select Auto to DIP to enable navigation to the DIP automatically after you jump.
• Select GO TO HARP to start navigation to the HARP.

the DIP, and a setting greater than 100% increases the drift distance. More experienced jumpmasters may
want to use smaller numbers, and less experienced skydivers may want to use larger numbers.
Safety Factor: Sets the margin of error for a jump (HAHO only). Safety factors are usually integer values of two
or greater, and are determined by the jumpmaster based on specifications for the jump.
K-Freefall: Sets the wind drag value for a parachute during freefall, based on the parachute canopy rating (HALO
only). Each parachute should be labeled with a K value.
K-Open: Sets the wind drag value for an open parachute, based on the parachute canopy rating (HAHO and
HALO). Each parachute should be labeled with a K value.
K-Static: Sets the wind drag value for a parachute during a static jump, based on the parachute canopy rating
(Static only). Each parachute should be labeled with a K value.

Heart Rate Variability Status
Your watch analyzes your wrist heart rate readings while you are sleeping to determine your heart rate variability
(HRV). Training, physical activity, sleep, nutrition, and healthy habits all impact your heart rate variability. HRV
values can vary widely based on gender, age, and fitness level. A balanced HRV status may indicate positive
signs of health such as good training and recovery balance, greater cardiovascular fitness, and resilience to
stress. An unbalanced or poor status may be a sign of fatigue, greater recovery needs, or increased stress. For
best results, you should wear the watch while sleeping. The watch requires three weeks of consistent sleep data
to display your heart rate variability status.
Color Zone Status Description
Green
Balanced Your seven-day average HRV is within your baseline range.
Orange
Unbalanced Your seven-day average HRV is above or below your baseline range.
Red
Low Your seven-day average HRV is well below your baseline range.
No color
Poor
No status
Your HRV values are averaging well below the normal range for your age.
No status means that there is insufficient data to generate a seven-day average.
You can sync your watch with your Garmin Connect account to view your current heart rate variability status,
trends, and educational feedback.
Heart Rate Variability and Stress Level
Stress level is the result of a three-minute test performed while standing still, where the Descent device
analyzes heart rate variability to determine your overall stress. Training, sleep, nutrition, and general life stress
all impact how a runner performs. The stress level range is from 1 to 100, where 1 is a very low stress state and
100 is a very high stress state. Knowing your stress level can help you decide if your body is ready for a tough
training run or yoga.
Performance Condition
As you complete your activity, such as running or cycling, the performance condition feature analyzes your pace,
heart rate, and heart rate variability to make a real-time assessment of your ability to perform compared to
your average fitness level. It is approximately your real-time percentage deviation from your baseline VO2 max.
estimate.
Performance condition values range from -20 to +20. After the first 6 to 20 minutes of your activity, the device
displays your performance condition score. For example, a score of +5 means that you are rested, fresh, and
capable of a good run or ride. You can add performance condition as a data field to one of your training screens
to monitor your ability throughout the activity. Performance condition can also be an indicator of fatigue level,
especially at the end of a long training run or ride.
NOTE: The device requires a few runs or rides with a heart rate monitor to get an accurate VO2 max. estimate
and learn about your running or riding ability (About VO2 Max. Estimates, page68).
Viewing Your Performance Condition
This feature requires wrist-based heart rate or a compatible chest heart rate monitor.

Lactate Threshold
Lactate threshold is the exercise intensity at which lactate (lactic acid) starts to accumulate in the bloodstream.
In running, this intensity level is estimated in terms of pace, heart rate, or power. When a runner exceeds the
threshold, fatigue starts to increase at an accelerating rate. For experienced runners, the threshold occurs at
approximately 90% of their maximum heart rate and between 10 km and half-marathon race pace. For average
runners, the lactate threshold often occurs well below 90% of maximum heart rate. Knowing your lactate
threshold can help you determine how hard to train or when to push yourself during a race.
If you already know your lactate threshold heart rate value, you can enter it in your user profile settings (Setting
Your Heart Rate Zones, page103). You can turn on the Auto Detection feature to automatically record your
lactate threshold during an activity.

Training Status
These measurements are estimates that can help you track and understand your training activities. The
measurements require you to complete activities for two weeks using wrist-based heart rate or a compatible
chest heart rate monitor. Cycling performance measurements require a heart rate monitor and a power meter.
The measurements may seem inaccurate at first when the watch is still learning about your performance.
These estimates are provided and supported by Firstbeat Analytics. For more information, go to garmin.com
/performance-data/running.
Training status: Training status shows you how your training affects your fitness and performance. Your
training status is based on changes to your VO2 max., acute load, and HRV status over an extended time
period.
VO2 max.: VO2 max. is the maximum volume of oxygen (in milliliters) you can consume per minute per kilogram
of body weight at your maximum performance (About VO2 Max. Estimates, page68). Your watch displays
heat and altitude corrected VO2 max. values when you are acclimating to high heat environments or high
altitude (Heat and Altitude Performance Acclimation, page75).
HRV: HRV is your heart rate variability status over the last seven days (Heart Rate Variability Status, page70).
Acute load: Acute load is a weighted sum of your recent exercise load scores including exercise duration and
intensity. (Acute Load, page73).
Recovery time: The recovery time displays how much time remains before you are fully recovered and ready for
the next hard workout (Recovery Time, page75).
Training Status Levels
Training status shows you how your training affects your fitness level and performance. Your training status is
based on changes to your VO2 max., acute load, and HRV status over an extended time period. You can use
your training status to help plan future training and continue improving your fitness level.
No Status: The watch needs you to record multiple activities over two weeks, with VO2 max. results from
running or cycling, to determine your training status.
Detraining: You have a break in your training routine or you are training much less than usual for a week
or more. Detraining means that you are unable to maintain your fitness level. You can try increasing your
training load to see improvement.
Recovery: Your lighter training load is allowing your body to recover, which is essential during extended periods
of hard training. You can return to a higher training load when you feel ready.
Maintaining: Your current training load is enough to maintain your fitness level. To see improvement, try adding
more variety to your workouts or increasing your training volume.
Productive: Your current training load is moving your fitness level and performance in the right direction. You
should plan recovery periods into your training to maintain your fitness level.
Peaking: You are in ideal race condition. Your recently reduced training load is allowing your body to recover
and fully compensate for earlier training. You should plan ahead, since this peak state can only be maintained
for a short time.
Overreaching: Your training load is very high and counterproductive. Your body needs a rest. You should give
yourself time to recover by adding lighter training to your schedule.
Unproductive: Your training load is at a good level, but your fitness is decreasing. Try focusing on rest, nutrition,
and stress management.
Strained: There is imbalance between your recovery and training load. It is a normal result after a hard training
or major event. Your body may be struggling to recover, so you should pay attention to your overall health.

Tips for Getting Your Training Status
The training status feature depends on updated assessments of your fitness level, including at least one VO2
max. measurement per week (About VO2 Max. Estimates, page68). Indoor run activities do not generate a
VO2 max. estimate in order to preserve the accuracy of your fitness level trend. You can disable VO2 max.
recording for ultra run and trail run activities if you do not want those run types to affect your VO2 max. estimate
(Activities and App Settings, page54).
To get the most out of the training status feature, you can try these tips.
• At least one time per week, run or ride outdoors with a power meter, and reach a heart rate higher than 70% of
your maximum heart rate for at least 10 minutes.
After using the watch for one or two weeks, your training status should be available.
• Record all of your fitness activities on your primary training device, allowing your watch to learn about your
performance (Syncing Activities and Performance Measurements, page98).
• Wear the watch consistently while you sleep, to continue generating an up-to-date HRV status. Having a valid
HRV status can help maintain a valid training status when you do not have as many activities with VO2 max.
measurements.
Acute Load
Acute load is a weighted sum of your excess post-exercise oxygen consumption (EPOC) for the last several
days. The gauge indicates whether your current load is low, optimal, high, or very high. The optimal range is
based on your individual fitness level and training history. The range adjusts as your training time and intensity
increase or decrease.
Training Load Focus
In order to maximize performance and fitness gains, training should be distributed across three categories: low
aerobic, high aerobic, and anaerobic. Training load focus shows you how much of your training is currently in
each category and provides training targets. Training load focus requires at least 7 days of training to determine
if your training load is low, optimal, or high. After 4 weeks of training history, your training load estimate will
have more detailed target information to help you balance your training activities.
Below targets: Your training load is lower than optimal in all intensity categories. Try increasing the duration or
frequency of your workouts.
Low aerobic shortage: Try adding more low aerobic activities to provide recovery and balance for your higher
intensity activities.
High aerobic shortage: Try adding more high aerobic activities to help improve your lactate threshold and VO2
max. over time.
Anaerobic shortage: Try adding a few more intense, anaerobic activities to improve your speed and anaerobic
capacity over time.
Balanced: Your training load is balanced and provides all-around fitness benefits as you continue training.
Low aerobic focus: Your training load is mostly low aerobic activity. This provides a solid foundation and
prepares you for adding more intense workouts.
High aerobic focus: Your training load is mostly high aerobic activity. These activities help to improve lactate
threshold, VO2 max., and endurance.
Anaerobic focus: Your training load is mostly intense activity. This leads to rapid fitness gains, but should be
balanced with low aerobic activities.
Above targets: Your training load is higher than optimal, and you should consider scaling back the duration and
frequency of your workouts.
Load Ratio
Load ratio is the ratio of your acute (short-term) training load to your chronic (long-term) training load. It's
helpful for tracking your training load changes.
Appearance 73
Status Value Description
No Status None Load ratio will be visible after 2 weeks of training.

The short-term and long-term training loads are balanced. The optimal range is
based on your individual fitness level and training history.
High 1.5 to 1.9 Your short-term training load is higher than your long-term training load.
Very High 2.0 or higher
Your short-term training load is significantly higher than your long-term training
load.
About Training Effect
Training Effect measures the impact of an activity on your aerobic and anaerobic fitness. Training Effect
accumulates during the activity. As the activity progresses, the Training Effect value increases. Training Effect
is determined by your user profile information and training history, and heart rate, duration, and intensity of your
activity. There are seven different Training Effect labels to describe the primary benefit of your activity. Each
label is color coded and corresponds to your training load focus (Training Load Focus, page73). Each feedback
phrase, for example, "Highly Impacting VO2 Max." has a corresponding description in your Garmin Connect
activity details.
Aerobic Training Effect uses your heart rate to measure how the accumulated intensity of an exercise affects
your aerobic fitness and indicates if the workout had a maintaining or improving effect on your fitness level.
Your excess post-exercise oxygen consumption (EPOC) accumulated during exercise is mapped to a range of
values that account for your fitness level and training habits. Steady workouts at moderate effort or workouts
involving longer intervals (>180 seconds) have a positive impact on your aerobic metabolism and result in an
improved aerobic Training Effect.
Anaerobic Training Effect uses heart rate and speed (or power) to determine how a workout affects your ability
to perform at very high intensity. You receive a value based on the anaerobic contribution to EPOC and the
type of activity. Repeated high-intensity intervals of 10 to 120 seconds have a highly beneficial impact on your
anaerobic capability and result in an improved anaerobic Training Effect.
You can add Aerobic Training Effect and Anaerobic Training Effect as data fields to one of your training screens
to monitor your numbers throughout the activity.
Training Effect Aerobic Benefit Anaerobic Benefit
From 0.0 to 0.9 No benefit. No benefit.
From 1.0 to 1.9 Minor benefit. Minor benefit.
From 2.0 to 2.9 Maintains your aerobic fitness. Maintains your anaerobic fitness.

Recovery Time
You can use your Garmin device with wrist-based heart rate or a compatible chest heart rate monitor to display
how much time remains before you are fully recovered and ready for the next hard workout.
NOTE: The recovery time recommendation uses your VO2 max. estimate and may seem inaccurate at first. The
device requires you to complete a few activities to learn about your performance.
The recovery time appears immediately following an activity. The time counts down until it is optimal for you to
attempt another hard workout. The device updates your recovery time throughout the day based on changes in
sleep, stress, relaxation, and physical activity.
Recovery Heart Rate
If you are training with wrist-based heart rate or a compatible chest heart rate monitor, you can check your
recovery heart rate value after each activity. Recovery heart rate is the difference between your exercising heart
rate and your heart rate two minutes after the exercise has stopped. For example, after a typical training run,
you stop the timer. Your heart rate is 140bpm. After two minutes of no activity or cool down, your heart rate
is 90 bpm. Your recovery heart rate is 50 bpm (140 minus 90). Some studies have linked recovery heart rate to
cardiac health. Higher numbers generally indicate healthier hearts.
TIP: For best results, you should stop moving for two minutes while the device calculates your recovery heart
rate value.
NOTE: Your recovery heart rate is not calculated for low-impact activities, such as yoga.
Heat and Altitude Performance Acclimation
Environmental factors such as high temperature and altitude impact your training and performance. For
example, high altitude training can have a positive impact on your fitness, but you may notice a temporary
VO2 max. decline while exposed to high altitudes. Your Descent G2 watch provides acclimation notifications
and corrections to your VO2 max. estimate and training status when the temperature is above 22ºC (72ºF) and
when the altitude is above 800 m (2625 ft.). You can keep track of your heat and altitude acclimation in the
training status glance.
NOTE: The heat acclimation feature is available only for GPS activities and requires weather data from your
connected phone.
Pausing and Resuming Your Training Status
If you are injured or sick, you can pause your training status. You can continue to record fitness activities,
but your training status, training load focus, recovery feedback, and workout recommendations are temporarily
disabled.
You can resume your training status when you are ready to start training again. For best results, you need at
least one VO2 max. measurement each week (About VO2 Max. Estimates, page68).

Pairing Your Wireless Sensors
Before you can pair, you must put on the heart rate monitor or install the sensor.
The first time you connect a wireless sensor to your watch using ANT+ or Bluetooth technology, you must pair
the watch and sensor. If the sensor has both ANT+ and Bluetooth technology, Garmin recommends that you
pair using ANT+ technology. After they are paired, the watch connects to the sensor automatically when you
start an activity and the sensor is active and within range.
1 Bring the watch within 3m (10ft.) of the sensor.
NOTE: Stay 10m (33ft.) away from other wireless sensors while pairing.
2 Hold MENU.
3 Select Sensors & Accessories > Add New.
TIP: When you start an activity with the Auto Discover option enabled, the watch automatically searches for

• Select your sensor type.
After the sensor is paired with your watch, the sensor status changes from Searching to Connected. Sensor
data appears in the data screen loop or a custom data field. You can customize the optional data fields
(Customizing the Data Screens, page53).
Heart Rate Accessory Running Pace and Distance
The HRM-Fit and HRM-Pro series accessories calculate your running pace and distance based on your user
profile and the motion measured by the sensor on every stride. The heart rate monitor provides running pace
and distance when GPS is not available, such as during treadmill running. You can view your running pace and
distance on your compatible Descent watch when connected using ANT+ technology. You can also view it on
compatible third-party training apps when connected using Bluetooth technology.
The pace and distance accuracy improves with calibration.
Automatic calibration: The default setting for your watch is Auto Calibrate. The heart rate accessory calibrates
each time you run outside with it connected to your compatible Descent watch.
NOTE: Automatic calibration does not work for indoor, trail, or ultra run activity profiles (Tips for Recording
Running Pace and Distance, page90).
Manual calibration: You can select Calibrate & Save after a treadmill run with your connected heart rate
accessory (Calibrating the Treadmill Distance, page36).
Tips for Recording Running Pace and Distance
• Update your Descent watch software (Product Updates, page120).
• Complete several outdoor runs with GPS and your connected HRM-Fit or HRM-Pro series accessory. It's
important that your outdoor range of paces matches your range of paces on the treadmill.
• If your run includes sand or deep snow, go to the sensor settings, and turn off Auto Calibrate.
• If you previously connected a compatible foot pod using ANT+ technology, set the foot pod status to Off, or
remove it from the list of connected sensors.
• Complete a treadmill run with manual calibration (Calibrating the Treadmill Distance, page36).
• If automatic and manual calibrations don't seem accurate, go to the sensor settings, and select HRM Pace &
Distance > Reset Calibration Data.
NOTE: You can try turning off Auto Calibrate, and then manually calibrate again (Calibrating the Treadmill
Distance, page36).
Running Dynamics
Running dynamics is real-time feedback about your running form. Your Descent watch has an accelerometer to
calculate five running form metrics. For all six running form metrics, you must pair your Descent watch with the
HRM-Fit, HRM-Pro series accessory, or other running dynamics accessory that measures torso movement. For
more information, go to garmin.com/performance-data/running.
90 Sensors and Accessories
Metric Sensor Type Description
Cadence
Watch or compatible
accessory
Cadence is the number of steps per minute. It displays the total
steps (right and left combined).
Vertical oscil
lation
Watch or compatible
accessory
Vertical oscillation is your bounce while running. It displays the
vertical motion of your torso, measured in centimeters.
Ground contact
time
Watch or compatible
accessory
Ground contact time is the amount of time in each step that you
spend on the ground while running. It is measured in milliseconds.
NOTE: Ground contact time and balance are not available while
walking.
Ground contact
time balance
Compatible accessory
only
Ground contact time balance displays the left/right balance of your
ground contact time while running. It displays a percentage. For
example, 53.2 with an arrow pointing left or right.
Stride length
Watch or compatible
accessory
Stride length is the length of your stride from one footfall to the next.
It is measured in meters.
Vertical ratio
Watch or compatible
accessory
Vertical ratio is the ratio of vertical oscillation to stride length. It
displays a percentage. A lower number typically indicates better
running form.
Tips for Missing Running Dynamics Data
This topic provides tips for using a compatible running dynamics accessory. If the accessory is not connected
to your watch, the watch automatically switches to wrist-based running dynamics.
• Make sure you have a running dynamics accessory, such as the HRM-Fit or HRM-Pro series accessory.
• Pair the running dynamics accessory with your watch again, according to the instructions.
• If you are using an HRM-Fit or HRM-Pro series accessory, pair it with your watch using ANT+ technology,
rather than Bluetooth technology.
• If the running dynamics data display shows only zeros, make sure the accessory is worn right-side up.
NOTE: Ground contact time and balance appears only while running. It is not calculated while walking.
REMEMBER: Ground contact time balance is not calculated with wrist-based running dynamics.
Running Power
Garmin running power is calculated using measured running dynamics information, user mass, environmental
data, and other sensor data. The power measurement estimates the amount of power a runner applies to the
road surface, and it is displayed in watts. Using running power as a gauge of effort may suit some runners
better than using either pace or heart rate. Running power can be more responsive than heart rate for indicating
the level of effort, and it can account for the uphills, downhills, and wind, which a pace measurement does not
do. For more information, go to garmin.com/performance-data/running.
Running power can be measured using a compatible running dynamics accessory or the watch sensors. You
can customize the running power data fields to view your power output and make adjustments to your training
(Data Fields, page124). You can set up power alerts to be notified when you reach a specified power zone
(Activity Alerts, page56).
Running power zones are similar to cycling power zones. The values for the zones are default values based on
gender, weight, and average ability, and may not match your personal abilities. You can manually adjust your
zones on the watch or using your Garmin Connect account (Setting Your Power Zones, page104).

About Heart Rate Zones
Many athletes use heart rate zones to measure and increase their cardiovascular strength and improve their
level of fitness. A heart rate zone is a set range of heartbeats per minute. The five commonly accepted
heart rate zones are numbered from 1 to 5 according to increasing intensity. Generally, heart rate zones are
calculated based on percentages of your maximum heart rate.
Fitness Goals
Knowing your heart rate zones can help you measure and improve your fitness by understanding and applying
these principles.
• Your heart rate is a good measure of exercise intensity.
• Training in certain heart rate zones can help you improve cardiovascular capacity and strength.
If you know your maximum heart rate, you can use the table (Heart Rate Zone Calculations, page104) to
determine the best heart rate zone for your fitness objectives.
If you do not know your maximum heart rate, use one of the calculators available on the Internet. Some gyms
and health centers can provide a test that measures maximum heart rate. The default maximum heart rate is
220 minus your age.
102 User Profile
Setting Your Heart Rate Zones

Color Gauges and Running Dynamics Data
The running dynamics screens display a color gauge for the primary metric. You can display cadence, vertical
oscillation, ground contact time, ground contact time balance, or vertical ratio as the primary metric. The color
gauge shows you how your running dynamics data compare to those of other runners. The color zones are
based on percentiles.
Garmin has researched many runners of all different levels. The data values in the red or orange zones are
typical for less experienced or slower runners. The data values in the green, blue, or purple zones are typical
for more experienced or faster runners. More experienced runners tend to exhibit shorter ground contact times,
lower vertical oscillation, lower vertical ratio, and higher cadence than less experienced runners. However, taller
runners typically have slightly slower cadences, longer strides, and slightly higher vertical oscillation. Vertical
ratio is your vertical oscillation divided by stride length. It is not correlated with height.
Go to garmin.com/runningdynamics for more information on running dynamics. For additional theories and
interpretations of running dynamics data, you can search reputable running publications and websites.

Ground Contact Time Balance Data
Ground contact time balance measures your running symmetry and appears as a percentage of your total
ground contact time. For example, 51.3% with an arrow pointing left indicates the runner is spending more time
on the ground when on the left foot. If your data screen displays both numbers, for example 48–52, 48% is the
left foot and 52% is the right foot.
Color Zone
Red Orange Green Orange Red
Symmetry Poor Fair Good Fair Poor
Percent of Other Runners 5% 25% 40% 25% 5%
Ground Contact Time Balance >52.2%L 50.8–52.2%L 50.7%L–50.7%R 50.8–52.2%R >52.2%R
While developing and testing running dynamics, the Garmin team found correlations between injuries and
greater imbalances with certain runners. For many runners, ground contact time balance tends to deviate
further from 50–50 when running up or down hills. Most running coaches agree that a symmetrical running
form is good. Elite runners tend to have quick and balanced strides.
You can watch the gauge or data field during your run or view the summary on your Garmin Connect account
after your run. As with the other running dynamics data, ground contact time balance is a quantitative
measurement to help you learn about your running form.

Vertical Oscillation and Vertical Ratio Data
The data ranges for vertical oscillation and vertical ratio are slightly different depending on the sensor and
