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 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 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 illness (DCI) 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 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.

4 Diving

• 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.

Dive Modes

The Descent Mk1 device supports six dive modes. Each dive mode has four phases: dive pre-check, surface

display, in-dive, and post-dive.

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

displays simplified in-dive data, and 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, page 7). 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, page 7).

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.

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, page 8).

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 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.

UP Key: Allows you to disable the UP button during dive activities to prevent inadvertent button presses.

NOTE: This setting is disabled by default.

Deco Lockout: Allows you to disable the decompression lockout feature. This feature prevents single-gas and

multi-gas 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.

Time to surface (TTS): The estimated amount of time it will take to ascend to the surface, including

decompression and safety stops.

detergent, such as dishwashing liquid.

NOTE: Using too much detergent may damage the heart rate monitor.

• Do not put the heart rate monitor in a washing machine or dryer.

• When drying the heart rate monitor, hang it up or lay it flat.

Running Dynamics

You can use your compatible Descent device paired with the HRM-Run

™

accessory or other running dynamics

accessory to provide real-time feedback about your running form.

The running dynamics accessory has an accelerometer that measures torso movement in order to calculate six

running metrics.

Cadence: Cadence is the number of steps per minute. It displays the total steps (right and left combined).

Vertical oscillation: Vertical oscillation is your bounce while running. It displays the vertical motion of your

torso, measured in centimeters.

Ground contact time: 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: 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: Stride length is the length of your stride from one footfall to the next. It is measured in meters.

Vertical ratio: Vertical ratio is the ratio of vertical oscillation to stride length. It displays a percentage. A lower

number typically indicates better running form.

40 Heart Rate Features

Training with Running Dynamics

Before you can view running dynamics, you must put on a running dynamics accessory, such as the HRM-Run

accessory, and pair it with your device (Pairing Your Wireless Sensors, page 83). If your Descent Mk1 was

packaged with the accessory, the devices are already paired, and the Descent Mk1 is set to display running

dynamics data screens.

1 Select an option:

• If your running dynamics accessory and Descent Mk1 device are already paired, skip to step 7.

• If your running dynamics accessory and Descent Mk1 device are not already paired, complete all the steps

in this procedure.

2 Hold MENU.

3 Select Settings > Activities & Apps.

4 Select an activity.

5 Select the activity settings.

6 Select Data Screens > Add New.

7 Select a running dynamics data screen.

NOTE: The running dynamics screens are not available for all activities.

8 Go for a run (Starting an Activity, page 22).

9 Select UP or DOWN to open a running dynamics screen to view your metrics.

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 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.

Heart Rate Features 41

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

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 color 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

whether it is positioned at the chest (HRM-Pro

™

, HRM-Run, or HRM-Tri accessories) or at the waist (Running

Dynamics Pod accessory).

Tips for Missing Running Dynamics Data

If running dynamics data does not appear, you can try these tips.

• Make sure you have a running dynamics accessory, such as the HRM-Run accessory.

Accessories with running dynamics have on the front of the module.

• Pair the running dynamics accessory with your Descent device again, according to the instructions.

• If you are using the HRM-Pro accessory, pair it with your Descent device 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.

42 Heart Rate Features

Performance Measurements

These performance measurements are estimates that can help you track and understand your training activities

and race performances. 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. For more information, go to www.garmin.com

/physio.

NOTE: The estimates may seem inaccurate at first. The device 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.

Recovery time: The recovery time displays how much time remains before you are fully recovered and ready for

the next hard workout.

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.

Predicted race times: Your device uses the VO2 max. estimate and published data sources to provide a target

race time based on your current state of fitness. This projection also presumes you have completed the

proper training for the race.

HRV stress test: The HRV (heart rate variability) stress test requires a Garmin chest heart rate monitor. The

device records your heart rate variability while standing still for 3 minutes. It provides your overall stress

level. The scale is 1 to 100, and a lower score indicates a lower stress level.

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.

Functional threshold power (FTP): The device uses your user profile information from the initial setup to

estimate your FTP. For a more accurate rating, you can conduct a guided test.

Lactate threshold: Lactate threshold requires a chest heart rate monitor. Lactate threshold is the point where

your muscles start to rapidly fatigue. Your device measures your lactate threshold level using heart rate data

and pace.

Training Status

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.

44 Heart Rate Features

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. The trail run and

indoor run activities do not generate a VO2 max. estimate in order to preserve the accuracy of your fitness level

trend.

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, page 44).

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 athletic performance and

should increase as your level of fitness improves. The Descent Mk1 device requires wrist-based heart rate or a

compatible chest heart rate monitor to display your VO2 max. estimate. The device 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 device, your VO2 max. estimate appears as a number, description, and position on the color gauge. On

your Garmin Connect account, you can view additional details about your VO2 max. estimate, including your

fitness age. Your fitness age gives you an idea of how your fitness compares with a person of the same gender

and different age. As you exercise, your fitness age can decrease over time.

46 Heart Rate Features

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 140 bpm. 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.

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.

Viewing Your Predicted Race Times

For the most accurate estimate, complete the user profile setup (Setting Up Your User Profile, page 51), and set

your maximum heart rate (Setting Your Heart Rate Zones, page 52).

Your device uses the VO2 max. estimate (About VO2 Max. Estimates, page 45) and published data sources to

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, telling you how

the activity has improved your fitness. Training Effect is determined by your user profile information, heart rate,

duration, and intensity of your activity.

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 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.

It is important to know that your Training Effect numbers (from 0.0 to 5.0) may seem abnormally high during

your first few activities. It takes several activities for the device to learn your aerobic and anaerobic fitness.

You can add Training Effect as a data field to one of your training screens to monitor your numbers throughout

the activity.

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.

48 Heart Rate Features

Viewing Your Heart Rate Variability and Stress Level

This feature requires a Garmin chest heart rate monitor. Before you can view your heart rate variability (HRV)

stress level, you must put on a heart rate monitor and pair it with your device (Pairing Your Wireless Sensors,

page 83). If your Descent Mk1 device was packaged with a heart rate monitor, the devices are already paired.

TIP: Garmin recommends that you measure your stress level at approximately the same time and under the

same conditions every day.

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, page 45).

Viewing Your Performance Condition

This feature requires wrist-based heart rate or a compatible chest heart rate monitor.

2 Go for a run or ride.

After 6 to 20 minutes, your performance condition appears.

3 Scroll to the data screen to view your performance condition throughout the run or ride.

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, page 52).

Heart Rate Features 49

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, page 53) 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.

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.

Acquiring Satellite Signals

The device may need a clear view of the sky to acquire satellite signals. The time and date are set automatically

based on the GPS position.

1 Go outdoors to an open area.

The front of the device should be oriented toward the sky.

2 Wait while the device locates satellites.

It may take 30–60 seconds to locate satellite signals.

Improving GPS Satellite Reception

• Frequently sync the device to your Garmin account:

◦ Connect your device to a computer using the USB cable and the Garmin Express application.

◦ Sync your device to the Garmin Dive app using your Bluetooth enabled smartphone.

◦ Connect your device to your Garmin account using a Wi‑Fi wireless network.

While connected to your Garmin account, the device downloads several days of satellite data, allowing it to

quickly locate satellite signals.

• Take your device outside to an open area away from tall buildings and trees.

• Remain stationary for a few minutes.

The temperature reading is not accurate

Your body temperature affects the temperature reading for the internal temperature sensor. To get the most

accurate temperature reading, you should remove the watch from your wrist and wait 20 to 30 minutes.

You can also use an optional tempe external temperature sensor to view accurate ambient temperature

readings while wearing the watch.

90 Troubleshooting

Maximizing the Battery Life

You can do several things to extend the life of the battery.

• Reduce the backlight timeout (Changing the Backlight Settings, page 82).

• Reduce the backlight brightness.

• Use UltraTrac GPS mode for your activity (UltraTrac, page 74).

• Turn off Bluetooth wireless technology when you are not using connected features (Connected Features,

page 31).

• When pausing your activity for a longer period of time, use the resume later option (Stopping an Activity,

page 22).

• Turn off activity tracking (Turning Off Activity Tracking, page 55).

• Use a watch face that is not updated every second.

For example, use a watch face without a second hand (Customizing the Watch Face, page 78).

• Limit the smartphone notifications the device displays (Managing Notifications, page 32).

• Stop broadcasting heart rate data to paired Garmin devices (Broadcasting Heart Rate Data to Garmin Devices,

page 38).

• Turn off wrist-based heart rate monitoring (Turning Off the Wrist-based Heart Rate Monitor, page 39).

NOTE: Wrist-based heart rate monitoring is used to calculate vigorous intensity minutes and calories burned.

Activity Tracking

For more information about activity tracking accuracy, go to garmin.com/ataccuracy.

My daily step count does not appear

The daily step count is reset every night at midnight.

If dashes appear instead of your step count, allow the device to acquire satellite signals and set the time

automatically.

My step count does not seem accurate

If your step count does not seem accurate, you can try these tips.

• Wear the device on your non-dominant wrist.

• Carry the device in your pocket when pushing a stroller or lawn mower.

• Carry the device in your pocket when actively using your hands or arms only.

NOTE: The device may interpret some repetitive motions, such as washing dishes, folding laundry, or

clapping your hands, as steps.

The step counts on my device and my Garmin Connect account don't match

The step count on your Garmin Connect account updates when you sync your device.

1 Select an option:

• Sync your step count with the Garmin Connect application (Using Garmin Connect on Your Computer,

page 34).

• Sync your step count with the Garmin Connect app (Manually Syncing Data with Garmin Connect, page 34).

2 Wait while the device syncs your data.

Syncing can take several minutes.

NOTE: Refreshing the Garmin Connect app or the Garmin Connect application does not sync your data or

update your step count.

Troubleshooting 91

The floors climbed amount does not seem accurate

Your device uses an internal barometer to measure elevation changes as you climb floors. A floor climbed is

equal to 3 m (10 ft.).

• Avoid holding handrails or skipping steps while climbing stairs.

• In windy environments, cover the device with your sleeve or jacket as strong gusts can cause erratic

readings.

My intensity minutes are flashing

When you exercise at an intensity level that qualifies toward your intensity minutes goal, the intensity minutes

flash.

Exercise for at least 10 consecutive minutes at a moderate or vigorous intensity level.
