BUILT-IN LED FLASHLIGHT WORKS ABOVE OR BELOW WATER

WHAT YOU'LL LOVE

AIR INTEGRATION

Pair with our Descent T2 transceivers (sold separately) for integrated pressure monitoring on up to 8 tanks via the SubWave sonar data network.

SUBWAVE SONAR NETWORKING

Exchange preset diver-to-diver messages up to 30 meters as well as monitor tank pressures and depth for up to 8 divers within a range of 10 meters¹.

DIVE MODES

Get multiple dive modes for single and multiple gas dives (including nitrox and trimix), gauge, apnea, apnea hunt and closed-circuit rebreather.

DIVE READINESS TOOL

This Garmin first technology shows how lifestyle factors such as sleep, exercise, stress and jet lag can affect your body — to help gauge when you are best prepared to dive.

DIVEVIEW MAPS

Color maps on your wrist offer bathymetric depth contours and more than 4,000 dive sites to help you discover new places to dive and get oriented.

DIVE-FOCUSED DESIGN

With its bright 1.2” AMOLED color display, sapphire lens, 200-meter dive-rated case and leakproof metal inductive buttons, this watch is built to go deep.

A STANDARD ABOVE FOR YOUR WORLD BELOW

DIVE FEATURES

BUILT-IN LED FLASHLIGHT

See and be seen with variable light intensities and strobe modes, in or out of the water.

DIVE LOG

Store and review data, track gear, take notes — and share via the Garmin Dive smartphone app.

LONG BATTERY LIFE

Stay in the water longer with up to 66 hours in dive mode plus up to 25 days in smartwatch mode.

CUSTOMIZABLE DIVE MODES

Add additional screens for each dive mode that features the fields you want to see.

SURFACE GPS

Track your entry and exit points on the surface with advanced satellite connectivity.

Garmin Dive App

Pair the app with your Descent dive computer to automatically sync and upload your dive logs.

LUME MODE

To aid readability and help maintain night vision, an ambient light sensor gives a green luminescence to your watch face in low-light conditions.

DIVE COMPASS

Built-in ABC sensors, including an underwater compass, help navigate every part of your dive.

REFERENCE POINT

Use this GPS tool for surface navigation to a dive site, so you can drop right onto your target every time.

VARIOMETER

This tool helps you monitor your freedive descent and ascent rates through tone and vibration feedback.

BIG NUMBERS MODE

Get a simplified dive screen on your wrist, with larger text to see critical diving data.

TIDE DATA

Stay up to date on ocean conditions by pairing your Descent device with your compatible smartphone.

INREACH DEVICE COMPATIBLE

Pair with inReach devices² and the inReach dive case for satellite messaging off-grid.

NDL AWARE DEPTH METRICS

Extend your bottom time with NDL Aware depth metrics that work in real time to show how specific depth changes can impact your no-decompression limit (NDL).

POST-DIVE ACTIVITY GUIDANCE

Physical fitness is important for divers, but exercising shortly after a dive can increase the risk of decompression sickness. Post-dive activity guidance alerts you when it may be a good idea to postpone your training due to a recent dive.

SIDEMOUNT TANK SWITCH GUIDANCE

When diving with sidemounted tanks, receive visual guidance on your compatible Descent dive computer paired with a Descent T2 transceiver as a reminder to switch tanks at a preset pressure value. This allows you to keep tank buoyancy balanced and properly manage a redundant gas supply throughout your dive.
