Best Dive Computer Ever!
on February 27, 2025
Posted by: WaterdogsRich
I’ve been diving for 30 years and have seen dive computers become common. Having used almost every watch computer that came, out I can confidently say there isn’t another one to match the Descent Mark 3i. Get it from a dive shop and they will show you all the amazing features it offers

All I’ve wanted and more
on February 25, 2025
Posted by: Rico Diver
I had the MK1 one, but I covered it when the MK2 came out…The MK3 is the dream machine!
Extremely bright screen, the ability to change your gas underwater (I accidentally had mindset as air and I was able to correct/switch it on the fly) was the best!! I may just get rid of my primary integrated computer and use this full-time! But for now it’ll remain my super pack up time depth monitor.

Incredible battery life
on February 25, 2025
Posted by: Philip23842
I upgraded from a Samsung watch 44mm the battery life on the garmin is incredible. The health tracking is also so much better than the Samsung. I went diving with my local dive shop and the owner was asking about it and now he is looking into being a seller of garmin. I can't wait to get a T2 transponder to try it out with the watch.

Great upgrade to an already great computer,
on February 8, 2025

I was on the fence about getting the MK3i, but really liked some of the new features and thought I would give it a try.
My MK2i is an outstanding dive computer and worked well for me as both a dive computer and smart watch. I like the idea of being able to send messages underwater but what sold me was the new, brighter display. It is truly a game changer.
Additionally, I use the Garmin InReach Mini 2 in the dive case whenever I dive. The ability to send messages when I surface, from my watch, to my family and friends was good with the MK2i; but, the interface to type in messages with the MK3i is at a whole new level.

Best Watch Ever - Hands down!
on January 13, 2025
Posted by: Stickman
I've been a Garmin watch fan for decades! When the very first G-Shock came out I was so impressed with it's ruggedness and features that I continued wearing it for years upon years! I then bought a boat and thought it was very cool to purchase a Quatix - a watch that had a trickle solar charger built right in was amazing! Now with the Descent Mk3i, I can track all of the activities I've used my watches for in the past, but NOW being a Scuba Diver who dives about 50 dives/year my dive computer (along with all of those wonderful tracking abilities of the past) are on my wrist in a beautiful screen! I love the look, the feel, and the ability of this watch - along with the battery life of 26+ days! Great job Garmin! You really knocked it our of the park with this device!

Great FAILURE!!,
on January 9, 2025
Posted by: Solares
I dive this one once, connected with the app, updated software, shut off. Five days later I tried to turn on and nothing happened. Never turn on. I follow instructions to soft reset, noting, hard reset and nothing so far. I send you a email to you and NO ANSWER.
Beyond disappointment right now.
