More then I expected
on July 5, 2025
Posted by: Streetbob
I purchased the Garmin Decent MK3I based solely on its ability to monitor my dive buddy's depth and tank pressure at up to 10 meters. I felt the other features were the same or comparable to other brands. This dive computer is super eazy to use yet capable of serving the requirements of the most advanced tech diver. I will never find Descent inadequate but the great folks at Garmin will, I'm sure will have me wanting the next iteration. Features I was not looking for or interested in are winning me over. If you are looking for a dive computer don't make your choice with out a close look at Garmin Descent.

Amazing dive computer

My wife surprised me with this computer. I love the features. I use it for running, strength training, and diving. When diving everything is easy to use and I really like the messaging feature with sub wave. Couldn’t be more happy with purchase.

Great battery life, supports a lot of activities

The watch is super comfortable, fits pretty nicely, and is easy to put on and off. It doesn’t feel too heavy for the volume.
I use it to record my runs, my hikes, and got it to go scuba diving with but haven’t done that yet.
The heart rate monitor is pretty good, on par with most others. I got the hrm200 from garmin and it pairs nicely with it.
The battery life is phenomenal especially coming from an Apple Watch. It’s easy to forget where the charger even is. (15-20 days easily, even with daily 1h+ activity recording)
I have been enjoying their concept of body battery, it has brought some awareness to the need for rest and recover properly to me!

This thing rocks
on July 31, 2025

I’m a scuba instructor and also relatively active and the versatility in this watch is super convenient. The interface is also customizable so can adjust as you like. I can’t read analog clocks so the digital option with my heartbeat is sick. I have the titanium band so I had to take a couple digits off because I have tiny wrists but it’s super cozy and can’t even feel it there sometimes. Would buy for my kids if I had any, and would teach them Muay Thai so no one would steal it from them because this thing is cool

I have yet to dive with this watch but it was incredibly easy to set up. The battery lasts for a full 25 days however I charge it about every 10 days. Looks great and I actually like wearing it constantly.

Fantastic Dive and Everyday Watch
on August 8, 2025
Posted by: Kohle K
Having already owned the Fenix 5 and 7X, I was already a fan of the Fenix line. During a dive trip 120' down in the famous "The Pit" cenote in Tulum, my dive computer crapped out. My buddy finned by, the bright, crisp screen of his Garmin Descent Mk3i clearly visible even from several meters away. I ordered one that night!
After wearing it for a year: Fantastic screen, snappy performance, no issues syncing. A marked improvement over previous Fenix watches. Fantastic dive computer that makes it very easy to switch between gases. I use the light daily...it's no gimmick...great for both underwater as a handy light and for everyday nighttime bathroom trips. I would have ZERO hesitation recommending this. Especially if you don't already own a smartwatch and a dive computer, this is a 2-for-1 and solves both needs fantastically. Good job Garmin.

The watch that does it all
on August 25, 2025
Posted by: Cip95
I have had my MK3i for about a year and it does everything I want, need and more. I use it primarily for diving, and it has performed as well as other dive computers I have owned. I also use for mountain biking, heart rate, altitude, hiking and running. As I contiune to explore the watch features I find more and more that I love about it. great buy!!!!
