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.
• 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 sickness (DCS) 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 DCS 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 DCS. 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 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. You should also stay with
others for an extended time after a dive, because the potential onset of decompression sickness (DCS) may
be delayed or triggered by surface activities.
• 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 DCS.
• 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 DCS.
• Disabling the deco lockout feature on the device can result in an increased risk of DCS, 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.
4 Diving
Dive Modes
The Descent G1 device supports six 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, page6). The surface phase shows the data screens for the dive mode (Dive Data Screens,
page8). 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, page19).
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.
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.
Diving 5
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, page7). 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 allows you to set a custom gradient factor.
NOTE: Make sure you understand gradient factors before entering a custom level of conservatism.
Water Type: Allows you to select the water type.
PO2: Sets the partial pressure of oxygen (PO2) thresholds, in bar, for decompression, warnings, and critical
alerts (Setting PO2 Thresholds, page7).
Alerts: Allows you to set tone, vibration, or silent alerts for depth and time. You can enable different alerts for
different dive modes.
Apnea Surf. Alert: Allows you to set alerts for apnea surface intervals.
Safety Stop: Allows you to change the safety stop duration.
Last Deco Stop: Allows you to set the depth of the final decompression stop.
End Dive Delay: Allows you to set the length of time before the device ends and saves a dive after surfacing.
CCR Setpoints: Allows you to set high and low PO2 setpoints for closed-circuit rebreather (CCR) dives (Setting
CCR Setpoints, page8).
Backlight: Allows you to adjust the backlight settings for dive activities. You can enable the backlight
throughout the dive or only when you are at depth.
Heart Rate: Allows you to enable or disable a heart rate monitor for dives. The Stored Strap Data option allows
you to enable a chest heart rate monitor, such as the HRM-Swim
™
or HRM-Tri
™
device, 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.
Double Tap to Scroll: Allows you to double tap the device to scroll through the dive data screens. If you notice
accidental scrolling, you can use the Sensitivity option to adjust the responsiveness.
UP Key: Allows you to enable or disable the UP button during dive activities to prevent inadvertent button
presses.
Silent Diving: Allows you to disable all tones and vibrations for alerts during dive activities.
No-Fly Time: Allows you to set the no-fly countdown timer mode (No-Fly Time, page8).
Deco Lockout: Allows you to disable 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 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.

Swim Terminology
Length: One trip down the pool.
Interval: One or more consecutive lengths. A new interval starts after a rest.
Stroke: A stroke is counted every time your arm wearing the device completes a full cycle.
Swolf: Your swolf score is the sum of the time for one pool length and the number of strokes for that length.
For example, 30 seconds plus 15 strokes equals a swolf score of 45. For open water swimming, swolf is
calculated over 25 meters. Swolf is a measurement of swimming efficiency and, like golf, a lower score is
better.

bike or indoor trainer. GPS is turned off for indoor activities (Activities and App Settings, page38).
When running or walking with GPS turned off, speed, distance, and cadence are calculated using the
accelerometer in the watch. The accelerometer is self-calibrating. The accuracy of the speed, distance, and
cadence data improves after a few outdoor runs or walks using GPS.
TIP: Holding the handrails of the treadmill reduces accuracy.
When cycling with GPS turned off, speed and distance data are not available unless you have an optional sensor
that sends speed and distance data to the watch, such as a speed or cadence sensor.

These estimates are provided and supported by Firstbeat Analytics
™
. For more information, go to garmin.com
/performance-data/running.
NOTE: The estimates may seem inaccurate at first. The watch requires you to complete a few activities to learn
about your performance.
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, page53).
Predicted race times: Your watch uses the VO2 max. estimate and your training history to provide a target race
time based on your current state of fitness (Viewing Your Predicted Race Times, page54).
Performance condition: Your performance condition is a real-time assessment after 6 to 20 minutes of activity.
It can be added as a data field so you can view your performance condition during the rest of your activity. It
compares your real-time condition to your average fitness level (Performance Condition, page54).
Functional threshold power (FTP): The watch uses your user profile information from the initial setup to
estimate your FTP. For a more accurate rating, you can conduct a guided test (Getting Your FTP Estimate,

Lactate threshold: Lactate threshold requires a chest heart rate monitor. Lactate threshold is the point where
your muscles start to rapidly fatigue. Your watch measures your lactate threshold level using heart rate data
and pace (Lactate Threshold, page55).
About VO2 Max. Estimates
VO2 max. is the maximum volume of oxygen (in milliliters) you can consume per minute per kilogram of body
weight at your maximum performance. In simple terms, VO2 max. is an indication of cardiovascular strength
and should increase as your level of fitness improves. The Descent G1 watch requires wrist-based heart rate or
a compatible chest heart rate monitor to display your VO2 max. estimate. The watch has separate VO2 max.
estimates for running and cycling. You must run either outside with GPS or ride with a compatible power meter
at a moderate level of intensity for several minutes to get an accurate VO2 max. estimate.
On the watch, your VO2 max. estimate appears as a number and description. On your Garmin Connect account,

Lactate Threshold
Lactate threshold is the exercise intensity at which lactate (lactic acid) starts to accumulate in the bloodstream.
In running, it is the estimated level of effort or pace. 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 10k 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, page79). You can turn on the Auto Detection feature to automatically record your
lactate threshold during an activity.
Appearance 55
Performing a Guided Test to Determine Your Lactate Threshold

to accept or decline the estimate.
Training Status
These measurements are estimates that can help you track and understand your training activities. The
measurements require a few activities using wrist-based heart rate or a compatible chest heart rate monitor.
Cycling performance measurements require a heart rate monitor and a power meter.
These estimates are provided and supported by Firstbeat Analytics. For more information, go to garmin.com
/performance-data/running.
NOTE: The estimates may seem inaccurate at first. The watch requires you to complete a few activities to learn
about your performance.
Training status: Training status shows you how your training affects your fitness and performance. Your
training status is based on changes to your training load and VO2 max. 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, page53). 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, page57).
Training load: Training load is the sum of your excess post-exercise oxygen consumption (EPOC) over the last 7
days. EPOC is an estimate of how much energy it takes for your body to recover after exercise (Training Load,
page57).
Training load focus: Your watch analyzes and distributes your training load into different categories based on
the intensity and structure of each activity recorded. Training load focus includes the total load accumulated
per category, and the focus of the training. Your watch displays your load distribution over the last 4 weeks
(Training Load Focus, page58).
Recovery time: The recovery time displays how much time remains before you are fully recovered and ready for
the next hard workout (Recovery Time, page59).
56 Appearance
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 training load and VO2 max. over an extended time period. You can use your training
status to help plan future training and continue improving your fitness level.
Peaking: Peaking means that 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.
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.
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.
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.
Unproductive: Your training load is at a good level, but your fitness is decreasing. Your body may be struggling
to recover, so you should pay attention to your overall health including stress, nutrition, and rest.
Detraining: Detraining occurs when you are training much less than usual for a week or more, and it is affecting
your fitness level. You can try increasing your training load to see improvement.
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.
No Status: The device needs one or two weeks of training history, including activities with VO2 max. results
from running or cycling, to determine your training status.
Tips for Getting Your Training Status
The training status feature depends on updated assessments of your fitness level, including at least two VO2
max. measurements per week. Your VO2 max. estimate is updated after outdoor runs or rides with power during
which your heart rate reached at least 70% of your maximum heart rate for several minutes. 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, page38).
To get the most out of the training status feature, you can try these tips.
• At least two times 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 device for one week, your training status should be available.
• Record all of your fitness activities on this device, or enable the Physio TrueUp feature, allowing your device
to learn about your performance (Syncing Activities and Performance Measurements, page91).
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 G1 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.
Training Load
Training load is a measurement of your training volume over the last seven days. It is the sum of your excess
post-exercise oxygen consumption (EPOC) measurements for the last seven days. The gauge indicates whether
your current load is low, high, or within the optimal range to maintain or improve your fitness level. The optimal
range is determined based on your individual fitness level and training history. The range adjusts as your
training time and intensity increase or decrease.
Appearance 57
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.
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, page58). 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 sec) 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 TE and Anaerobic TE as data fields to one of your training screens to monitor your
numbers throughout the activity.

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.
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 two VO2 max. measurements each week (About VO2 Max. Estimates, page53).

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, page80) 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.

Color Gauges and Running Dynamics Data
In the Garmin Connect activity, the running dynamics data displays as colored graphs. The color zones are
based on percentiles and show you how your running dynamics data compare to those of other runners.
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 www.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
NOTE: In the Garmin Connect activity, the running dynamics data displays as colored graphs.
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.
114 Appendix
Vertical Oscillation and Vertical Ratio Data
NOTE: In the Garmin Connect activity, the running dynamics data displays as colored graphs.
The data ranges for vertical oscillation and vertical ratio are slightly different depending on the sensor and
whether it is positioned at the chest (HRM-Pro, HRM-Run
™
, or HRM-Tri accessories) or at the waist (Running
Dynamics Pod accessory).
