New Garmin Descent Mk3 & T2 Tank Transmitter Featuring Diver-Diver Messaging from 30 Meters Away

Garmin's new Descent Mk3 Series, the perfect holiday gift for divers! Improves further on the already popular Descent dive computer platform.

Garmin Descent Mk3 Series Overview

The Garmin Descent Mk3 watch-style dive computers and Descent T2 Tank Transceiver with enhanced SubWave sonar technology that – through a soon-to-be-released software update – will add diver-to-diver messaging and Diver Assistance 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 66 hours of battery life in dive mode for 51mm Descent Mk3i.

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.

New Notable Garmin Descent Mk3 features vs. Mk2

New advancements on the Descent Mk3 series make it possible to dive with greater peace of mind.

    Diver Assistance (coming soon): If a diver is in need of help, this revolutionary tool will let them request assistance right from their watch thanks to enhanced SubWave sonar technology. When using a Descent Mk3i dive computer and Descent T2 transceiver, divers will be able to send out an assistance alert to other connected divers. Nearby connected divers will then be able to see the diver’s depth and distance and monitor them until assistance is no longer required.

    Diver-to-diver messaging (coming soon): Using SubWave technology, divers with a Descent Mk3i and Descent T2 transceiver will be able to exchange preset messages with other connected divers, up to 30 meters away.
    Dive group tracking: Using air integration, keep track of where other divers are in the group. See depth and tank pressure of up to eight divers who are using a Descent T2 transceiver, up to 10 meters away.

    Dive-focused design: A 200-meter dive-rated case with a strong, scratch resistant sapphire lens operates at twice the depth of the previous generations and features metal buttons that are leakproof and fully functional at 200 meters. Plus, a bright touchscreen AMOLED display provides greater visibility—even underwater.

    Built-in LED flashlight: Available on the 51mm Descent Mk3i, an integrated LED flashlight with built-in strobe mode gives divers greater visibility in low-light conditions, above or below the water.

    Dive readiness: See how lifestyle factors like sleep, exercise, stress and jet lag can affect the body’s overall preparedness to dive. A higher readiness score may suggest it’s time to dive in while a lower score may be reason to consider using a higher conservatism setting or choose an easier dive.




              We let the Garmin Vice President of Global Consumer Sales sum it all up for you in a nut shell, we are as excited as he is about the Garmin Descent Mk3i Dive Computer! 

              “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.” –Dan Bartel, Garmin Vice President of Global Consumer Sales
