Diving this week in the Caymans and I LOVE this watch. Battery is amazing, little messages that pop up are easily read but not too much…I wear this daily as a baseball coach and love that it tracks my steps and you can cater the watch face to the best fit for you. No complaints whatsoever. Excited to get a new watch strap that is more comfortable for daily use.

Excellent dive watch

After using my Fenix 8 on a dive, I started looking at the MK3i as a possible replacement for our G2’s. The air integration is amazing and being able to track each other’s air consumption is a plus (or a minus if you are an air hog). It’s easy to read and has everything we need for diving and other sports activities.

Extremely Powerful

It tracks a tremendous amount of data and is an extremely powerful tool. The only reason it does not get 5 stars is how difficult it is to MASTER. It will take time and I am excited to get to that point t but it is not as user friendly as many other wearables even other Garmin products.

MK3i Dive Watch Initial Review
on July 10, 2026
Posted by: ScubaSteve
I bought this about a month ago in preparation for a dive trip. The functionality is impressive, covering many different activities. The online videos are helpful in initial set up and functionality regarding scuba diving. It’ll take me a while to work my way around all the functionality and all of the menus, but it’s well worth it. This is a very impressive dive watch. I completed my first dive with the watch yesterday and it matched the pressure and depth of my other Dive computer exactly. In addition, it provides a dive profile and water temp profile after each dive. Nothing but compliments for this new watch.

Loaded with functions.

Loaded with functions, but slower than FENIX. Starting up after initial power up or after sync with Garmin Connect seems to take 2-3x longer. Maybe time to update the product with a faster processor.
