Ton of options
on January 5, 2026
Posted by: JWalje
I really like all of of the options available, and learning how to use them takes time. I would really like to have the option of a smaller band than the 20 mm as it is still too big and am unable to find anything smaller that will fit my wrist.

Love!

I bought this a few weeks ago and I’m still figuring it out so far it’s amazing, except I cannot get my text messages from my phone on my watch. It will ring from my phone calls, but no text messages.

Great features but no connectivity to SSI app
on August 8, 2025
Posted by: Bayleeness
I purchased this mainly due to the smartwatch + dive computer capabilities.
Its hard to forget your dive computer when its already on your wrist!
I also love the connectivity with the InReach Mini! This produces an added safety feature for ocean dives!
As i swim and do other exercises, the other sports/workout features are an added plus.
I love the air integration with the transmitter as well!
The only thing that disappoints me is thr lack of connectivity with the SSI dive app.
Other brands have easy bluetooth uploading into the SSI app, which makes logging your dives for SSI certifications and awards a breeze. I ended up buying a cheap extra dive computer to accomplish the uploads to the SSI app. In my opinion, this is not something you should have to do after spending so much on the MK3i.
I have not yet used the underwater communication or maps yet on this watch but am excited to test out those capabilitiee on an upcoming boat dive trip!

Fantastic. It's more than just a dive watch

My husband bought this for for after I completed my advanced course. At first it seemed difficult to use. But on my first dive trip it was terrific. It's really easy and I love all the features

Smaller size than Mk2i
on May 14, 2025

Great watch smaller with better features battery life is less but acceptable. Didn't love the fact that Garmin is starting to charge for maps and extra fitness app features.

Not really what I expected
on April 27, 2025
Posted by: Chrisdjahn
I'm quite disappointed from the Mk3i. So far after unboxing and using it for about 1h
Nothing really works from the beginning. Compass calibration always errors.
Wpa3 for WiFi is not supported
The software looks edgy. And when you scroll, it just looks weird, the text looks cut of on the left side. Like it's using a 3rd party software that is not made for this Watch.
The settings are super confusing. Not intuitive at all.
I have sync problems to pretty much every single device.
Doesn't really work with the SSI ap either.
The charging clip is annoying too. It would be great if the clip itself had a USB C port instead of a cable attached. So I could use any charger.
That's so far and I haven't even been diving with it.

The Mk3i is where it’s at!

I got this for my birthday! It’s replacing my Mk2 and I love it! The size 43 and the gray color with gold accents! It’s a great dive watch and sport watch all in one!
