Garmin’s new Descent Mk3 series dive computers have 200-meter dive ratings, bright AMOLED displays and a built-in flashlight

Pair Descent Mk3i with the new Descent T2 transceiver for diver communication, Diver Assistance and tank pressure monitoring

Singapore, 15 November 2023 – Garmin Singapore today announced the Descent Mk3 series watch-style dive computers and Descent T2 transceiver with enhanced SubWave™ sonar technology that – through a soon-to-be-released software update – will add diver-to-diver messaging and Diver Assistance1 to tank pressure monitoring.

Purpose-built with a dive-first approach to design, the Descent Mk3 series comes in two sizes – 43mm and 51mm – with air integration options on both and feature a vibrant touchscreen AMOLED display, a 200-meter dive-rated case with metal leakproof buttons that are fully operational at that depth, and up to 48 hours of battery life in dive mode².

The 51mm Descent Mk3i also comes with a built-in LED flashlight for greater visibility in low-light conditions—even underwater. With tools like multiple dive modes, DiveView™ maps and dive readiness score, plus Garmin’s suite of health, fitness and connected features, the Descent Mk3 series helps divers make the most of their adventures above and below the surface.

“From recreational to technical and every dive in between, the Descent Mk3 series and Descent T2 transceiver add innovative new features to help you explore deeper waters. One of those being enhancements to our SubWave sonar technology, which now makes it possible to communicate with other divers and even request assistance from nearby divers when help is needed—right from the wrist. This, coupled with air integration, DiveView maps and dive readiness tools help make these premium dive computers an essential part of your dive kit.” – Mr. Scoppen Lin, Assistant General Manager, Garmin Asia.

Dive in

Designed by divers for divers, the Descent Mk3 series is ready for the next excursion with dive modes for single and multiple gas dives (including nitrox and trimix), gauge, apnea, apnea hunt and closed-circuit rebreather. Divers can customize additional data screens for each dive mode or choose a simplified dive screen with larger text to make it easier to see critical diving data. New DiveView maps offer bathymetric depth contours and more than 4,000 preloaded dive sites worldwide to help locate specific sites like shipwrecks, identify hotspots for spearfishing and more. Built-in sensors – like an altimeter, barometer, compass and even an underwater compass – help navigate a dive and surface GPS helps track entry and exit points on the surface. Divers can also use the variometer tool to monitor their freedive descent and ascent rates through tone and vibration feedback. Before diving in, users can check nearby tide conditions from their watch4 and use the reference point tool for surface navigation to a target dive site. Following a dive, the dive log lets users review data, track gear, take notes and share details via the Garmin Dive smartphone app.

Beyond the dive

Doubling as a premium multisport GPS smartwatch, the Descent Mk3 series includes dozens of preloaded activity profiles for trail running, swimming, hiking, golfing and more so users can track the ways they move. Premium fitness features5 like VO2 max, daily suggested workouts for running and cycling, endurance score and hill score can help users stay fit for their next dive while wellness insights like sleep monitoring, sleep score, Pulse Ox and Jet Lag Adviser can help users understand their body better.

Whether out exploring a new destination, or staying closer to home, the Descent Mk3 series has navigation and orientation features to help every step of the way. Preloaded TopoActive maps from around the world can help keep explorations on track while SatIQ technology can help provide superior positioning accuracy with multi-band GPS while optimizing battery life. Create or find existing courses in the Garmin Connect app and get turn-by-turn directions right from the watch, or enter a desired distance and get round-trip route suggestions that use TrendLine routing to find the best local paths.

Packed with connected features, the Descent Mk3 series lets divers: receive smart notifications; download songs from Spotify, Deezer or Amazon Music (premium subscription required) for phone-free listening; workout with greater peace of mind with incident detection and assistance; and more.
