Garmin Mk3i Dive Computer and Multisport GPS Smartwatch: Advanced, watch-style dive computer with 1.4” AMOLED display
Meet the Garmin Descent™ Mk3i—not just a dive computer, but a rugged, do-it-all companion for those who take their underwater adventures seriously. With its eye-popping 1.4” AMOLED display and a sapphire lens that laughs in the face of scratches, this beast is ready to plunge up to 200 meters without breaking a sweat. And here’s the kicker: thanks to SubWave™ sonar tech, you can chat (well, sort of) with up to seven other divers using preset messages, all while keeping tabs on tank pressures and depth. Pair it with the Descent™ T2 transceiver, and you’re basically the James Bond of diving.
But wait, there’s more (because of course there is):
- Ever fumbled in the dark? The built-in LED flashlight adjusts to your needs, because nobody likes a blinding light when they’re trying to read a compass.
- The dive readiness tool is like having a personal dive coach, minus the pep talks. It checks if you’re actually fit to dive today—because sometimes last night’s pizza party wasn’t the best idea.
- With DiveView™ maps, you’ve got over 4,000 dive sites at your fingertips, complete with bathymetric depth contours. It’s like Google Maps, but for finding Nemo.
- Multi-band GPS and ABC sensors ensure you won’t get lost (unless you want to).
- Store up to 200 dives in the dive log—perfect for reliving your underwater escapades or proving you actually did that deep dive.
- And because surface life matters too, it’s packed with sports apps and 24/7 health monitoring. Because why not?
