Incredible!!!!
on March 22, 2025
Posted by: Brad N
As an endurance athlete and data dude, I have been a HUGE Garmin fan for a long, long time! I am also a diver that depends on data for safety, so this was a no brainer!!! It does everything but put on my fins and clear my mask! Just an amazing, do everything computer on my arm! On a side note, this has the built-in flashlightI, (as does my FX7 Sapphire Solar) and once you have a flashlight on your arm you may never go back!

Great addition to my dive locker.

I’m a diving professional who enjoys a very active lifestyle. My last watch was a Garmin Fenix 5s and loved it. After almost 6 years I decided to upgrade to this one. It did not disappoint. It does everything my Older Fenix did plus my diving activities and new health analytics. I’m very happy with my new watch.

Not overly impressed so far

I haven't used it for diving yet, just smart watch mode so far. Display is nice and bright and battery life is as advertised. The inductive buttons on the other hand are hit and miss at best, Sometimes they work. Sometimes it takes multiple presses to get what I want. I question the long term reliability.

Mk3i 51mm

So far so good. I've only had it for a few weeks and this thing is awesome. If you ever choose to get into any other diving this watch will have you covered. Definitely worth the money. My only negative is for how much you pay i wish it included the heart monitor ekg tech but still worth it.

Best Dive Computer Ever!
on February 27, 2025

I’ve been diving for 30 years and have seen dive computers become common. Having used almost every watch computer that came, out I can confidently say there isn’t another one to match the Descent Mark 3i. Get it from a dive shop and they will show you all the amazing features it offers

All I’ve wanted and more

I had the MK1 one, but I covered it when the MK2 came out…The MK3 is the dream machine!
Extremely bright screen, the ability to change your gas underwater (I accidentally had mindset as air and I was able to correct/switch it on the fly) was the best!! I may just get rid of my primary integrated computer and use this full-time! But for now it’ll remain my super pack up time depth monitor.

Incredible battery life
on February 25, 2025
Posted by: Philip23842
I upgraded from a Samsung watch 44mm the battery life on the garmin is incredible. The health tracking is also so much better than the Samsung. I went diving with my local dive shop and the owner was asking about it and now he is looking into being a seller of garmin. I can't wait to get a T2 transponder to try it out with the watch.
