The Garmin Descent™ Mk3i Wrist Dive Computer is a revolutionary device for divers and for active individuals. When divers link the Descent™ T2 transceivers (sold separately) to this air-integrated wrist dive computer, it can monitor tank pressures and depth of up to 8 divers within a 10-meter range. Coming soon, after a required update, you’ll be able to communicate underwater with preset messages to your fellow divers. Choose between multiple dive modes for single and multiple gas dives and reach an astonishing depth of 200 meters with this dive computer. With an impressive battery life and preloaded features added to enhance your diving experience, the Mk3i is designed for diverse underwater activities.
When it is time to surface, the dive computer transforms into a versatile smartwatch. Beyond its diving capabilities, this device offers health and fitness features, helping users plan and achieve wellness goals through daily suggestions and expert coaching—all conveniently accessible from their wrist. Pairing the watch with a smartphone unlocks additional perks, including music playback, contactless payments, and seamless phone notifications. The Garmin Descent™ Mk3i Wrist Dive Computer combines dive computer features and smartwatch capabilities into one rugged and stylish device.

2 out of 5 stars
The watch has a lot of beneficial features, especially the marking of locations where dives start and end. Very cool, especially when I use it for work where marking accurate locations is important. I also use it when I mtn bike and bikepack. There are some great features that I love, but I mostly wanted to point out the negative aspects because they are so critical and could lead to very dangerous situations (not trying to exaggerate), hence the 2 start review. Here are a few really frustrating issues that I hope Garmin will consider improving on their next model (which may be out.?.?): - The touch screen is easily triggered when showering, crazy enough, so the screen should be turned off when showering. Took me a while to figure it out, but during a number of showers (before I started turning the screen off) the act of the water splashing on the screen toggled through menus and actually altered settings without my knowledge. A few times it altered the tank O2 mixtures way off, PO2 setting, from salt to fresh, and NDL limits, so I luckily noticed this before my dives. This unknown change could have made for a really bad day, and I couldn't believe this top of the line watch had this issue. If Garmin could have it where you could 'lock' critical settings, that would be perfect. - The audio is terribly quiet, even out of the water. Me and my wife both were amazing how quite the alarm is along with the haptic vibrations. Add being in the water with a hood on, with the exhaust from my reg, and also being tasked loaded, I missed a number of NDL alarms along with preset timers. The haptic was easily missed and is barely felt through my 5mm suit. If Garmin could improve these critical items, I would give this watch 10 stars.
