The Garmin Mk3I is a Great watch with amazing upgrades if compared with the MK2i. I already has the MK2i and upgraded to the 3 and is way better.

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
on August 12, 2026
Posted by: Desend160
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.
