MK3i
on February 23, 2024
Posted by: Anonymous
I've had my watch for about 3 weeks. So far, I like it. I have not had the opportunity to use the dive feature yet. Battery life is awesome. Not cheap but if you're a semi serious diver. It's worth looking at when it comes to a smart/dive watch.

Even better than the Mk2i
on February 28, 2024
Posted by: MrMikeD
I've taken my first trip with the new Mk3i and love it. I dove the Mk31 and Mk2i side by side, and the Mk3i is even easier to read. There was no noticeable difference in the two computer's dive management algorithms for the dive, so that awesome. The T1 and T2 transmitters were within 3 psi of each other from start to finish, so that too is awesome. That said, the Mk3i's T2 transmitter does emit a rather high pitch pulse every 10-12 seconds which isn't great, but whatever (as long as it doesn't scare-off the fish). I was able to pair with my buddy's new Mk3i/T2 setup for air monitoring and texting, and it works as expected. I really hope Garmin soon allows us to to make-up some of our own text messages/responses (using Connect I'm guessing) because the current stock messages are rather bland and boring. I did need to rethink the altimeter settings since the computer said I was at -65.4 feet when I was sitting in the boat (see the picture), but once I switched to having it use GPS for altimeter all was well.
All in all I'm super happy with the computer and I know my son is going to love getting my current Mk2i as a gift.. :)

Great Watch and Dive Computer.

I am a scuba instructor so the biggest feature I need is obviously the dive computer. I teach diving to 330’ with rebreathers and helium. That being said I need to put my life on the line and the Garmin is my safety net. It has not do disappointed!
The screen is perfect. The battery life is long so it doesn’t need constant recharging. And the apps bring it all together.
I want to figure out how to keep the watch screen on all the time, maybe dimmed but visible. That’s probably me though and an instruction book.
I would also like to lock the right side buttons so the watch doesn’t trip over to an app by accident.
I can’t express how much I love the Descent series of watches/dive computers. I have upgraded from each one and they simply get better and better.

Great watch and features
on March 7, 2024
Posted by: JohnDLan
This is an excellent watch and well worth the investment. The only thing I wish it had was a speaker/microphone so I could accept and make calls. However, I can understand why it doesn’t.

Great BUT....

Cons
1 My PSI is just as important as my depth. The PSI font size is HORRIBLE. Large font is just bold basically. I do not wear or need glasses either. The person that designed the PSI font size and PSI display location only used this in a pool or the Carribian Islands. Never in limited/low visibility waters.
2 Propriatary charging cable works great but super inconvenient. How about wireless charging its 2024.
3 The Tank transceivers noise is like a dripping faucet in the middle of the night.
PROS
The person that engineered the battery life should get a raise.

Great watch
on March 20, 2024
Posted by: hsa1
four dives in, replacing a standalone computer. this is a great dive watch; extremely intuitive to use underwater. I also use all of the other running and cycling features and they operate extremely well, as expected from Garmin.
