Amazing watch
on April 2, 2026
Posted by: BATTLEBUDDY101st
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

AMAZING FEATURES! Totally worth the price!

Super powerful device! Much more full featured than I even expected! So much relevant important outdoor data whether it’s tides, elevation, diving depth, etc., and NO Subscription. Love it! The map is incredibly clear and easy to read even for my 62-year-old eyes. Yes, it’s pricey But you get what you pay for.

Overall a great watch. Primarily use as a dive computer, which I give 4 stars since the T2 transmitter is always failing to update, and constantly drops communication with the watch despite my hand position never changing. Frustrating and sincerely hope that Garmin can fix in future updates.

I purchased this about a month ago and am very happy with it so far. I have not had a chance to dive with it yet but it is great for tracking pool and other work outs so far

As a dive computer I cannot imagine it being beat. I love it for golf and for biking. It does a good job of traking sleep and other health details. I wear it almost every minute of every day.

Garmin Descent Mk3i — A Game‑Changer for Serious D
on January 17, 2026
Posted by: Vet-Diver
The Garmin Descent Mk3i is easily one of the most impressive dive computers on the market today. Garmin took everything divers loved about the previous Descent models and elevated it with smarter tech, sharper visuals, and features that genuinely enhance safety, awareness, and enjoyment underwater.

Beautiful Watch

I've actually only had the watch about 2 weeks and that is why I'm giving it 4 stars instead of five. The one thing Garmin could do that would help immensely is the addition of a quick start fundamentals guide included in the box. Garmin assumes everyone is capable of finding all the information for functions of this watch thru the App and Websites but I found that the basic startup was just a little confusing. I've owned an Apple Watch prior so I had some understanding of basic setup. This watch blows Apple right out of the water with its bright easy to read face and functionality with buttons and touchscreen. I"m still learning about its different features and operation, but so far I couldn't be happier about its performance. I did add an App to referee soccer matches and that was the main reason for buying the watch so far is working great. I hope to get an opportunity to check out some of the scuba diving features this summer.
