  • Dive-first design with 200-meter dive-rated case includes metal leakproof inductive buttons and multiple dive modes for recreational to technical scuba diving and freediving
  • Enhanced SubWave sonar technology provides the ability to exchange preset diver-to-diver messages up to 30 meters (available with software v.15.70 or later) as well as monitor tank pressures and depth for up to eight divers within a range of 10 meters, when paired with the Descent T2 transceiver (sold separately) for group dive support
  • A dive readiness tool, developed by Garmin, shows how lifestyle factors such as sleep, exercise, stress and jet lag can affect your body’s overall preparedness for diving — offering guidance that can help you make better-informed dive plan decisions (data presented is intended to be a close estimation of metrics tracked)
  • Multi-band GPS technology provides superior positional accuracy while you’re out on the water, and built-in ABC sensors — including an underwater compass — help navigate every part of your dive from entry to exit (GPS tracking does not work underwater)
  • Dive logs automatically sync with the Garmin Dive app downloaded to your compatible smartphone, allowing you to share and review data, track gear, post photos, take notes and more

  • Enjoy everyday wearability, and live connected with smart notifications, music storage, Garmin Pay contactless payments and more (compatible smartphone required)
  • Battery performance: up to 10 days in smartwatch mode and up to 30 hours in dive mode — so you can dive without worrying about battery life and go longer between recharges


Discover a deeper connection with the Descent™ Mk3i watch-style dive computer. It features multiple dive modes plus SubWave™ sonar technology for diver-to-diver communication via preset messages (available with software v.15.70 or later). The device also supports monitoring of tank pressures and depth for up to eight networked divers, when paired with the Descent™ T2 transceiver (sold separately). Purpose-built specifically for divers, the Descent Mk3i dive computer combines a bright 1.2” AMOLED display with scratch-resistant sapphire lens, 200-meter dive-rated case and metal leakproof inductive buttons. DiveView™ maps offer bathymetric depth contours and more than 4,000 dive sites to help you find where to dive and get oriented. Plus, a dive readiness tool, developed by Garmin, shows how lifestyle factors such as sleep, exercise, stress and jet lag can affect your body’s overall preparedness for diving — so, ultimately, you can make better-informed dive plan decisions (data presented is intended to be a close estimation of metrics tracked). This dive computer is designed to help maximize your preparation for the physical and mental challenges of diving. You can also reference ABC sensors with a 3-axis underwater compass as well as surface GPS capabilities to mark your entry and exit points.

I dive on occasion and was wanting to work on motivation for improving my health. I completed 2 dives with the watch and it performed great. More importantly it has helped me identify bad habits that was wrecking my sleep quality. I also use it to track fitness activities and it works great for that as well. Happy with the purchase.

As a dive computer, this is great. Does everything you need it to. However, I bought this watch hoping to have it take over as a daily wearable coming from Apple Watch. I already thought the music playback experience on Apple was mediocre.. But wow. Garmin takes it to another level.The UI is TERRIBLE across the board and it is not even possible to do basic things like scrubbing back and forth in a podcast. I encountered shakey Bluetooth connection while running on 3 separate pairs of headphones using Garmin. My music would often desync L&R headphones, cut in and out, or just flat-out pause for no reason. This was only when in motion. Clearly, motion (running) is too much for Garmin to handle when using wireless headphones.I was attracted to this watch because I thought it would serve as my dive computer AND my daily smartwatch. I would advise anybody to just get a much cheaper, dedicated dive computer and continue to use whatever watch you're happiest with for other activities.
