Great battery life, supports a lot of activities
on July 13, 2025

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!

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.

More then I expected

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.

I recently bought it with the main purpose of being a dive computer, I’m starting to use more of the features and the deeper I get to know it, the more I love it. Simply amazing
