Rocks from 30 feet to 330 feet

The MK3i is easy to use, easy to see and covers all the bases. Though my primary use for it is diving, it is also my daily wear fitness watch for all my other activities. As an active instructor, and technical dive instructor, i heartily recommend the Mk3I to my students at all levels. From 30 feet to 330 feet the Mk3i is a solid and critical part of my dive kit!

Amazing watch

I just recently purchased this watch. My previous Garmin was a Garmin Tactix 8. Another fine watch but I needed a watch that I can take with me scuba diving. Haven't used that function yet but, the rest of the watch is amazing I received several positive comments about it while I'm out and about. Easy to use, and it looks great. Thank you

MK3i Dive Watch Initial Review

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.
