High-Performance Dive Watch with Unmatched Versatility and Safety Features
Style: Mk3i
Color: Black Titanium
I recently took the Mk3i with me to the Philippines for diving, and it exceeded my expectations. The battery life is outstanding, and it performed flawlessly during my SCUBA dives. I paired it with the wireless air pod for my tank, which allowed me to monitor my air supply or track a less experienced diver—an excellent safety feature, even though the pods are a bit pricey. I opted for the larger model with a built-in flashlight, which I initially thought I wouldn’t use but now rely on all the time. The red light mode is especially useful for staying visible when walking on dark streets at night. With so many features packed into this watch, it’s a top-tier dive computer and more. The only small downside is that the buttons can be too easily pressed, but it's not a deal-breaker. If you can invest in it, I highly recommend it for its versatility, durability, and safety-enhancing features.

The best of both worlds
Style: Mk3i
Color: Black/Pebble Gray
The Garmin mk3i 51 mm is my go to watch for fitness training and scuba diving. I've tested the watch for a month. Gym workouts several times a week, and multiple dives to around 85 feet. It's very durable in both. With a minor scratch on the glass. I recommend putting a screen protector on it when you first get the watch. Value for the money? Yes if you are in need of a fitness tracker and dive computer. You get the best of both worlds. 100% yes! Buy this watch if you are very active in and out of the water. You'll never use all it has to offer, but you'll have room to grow and change your outdoor life style.

chose this over fenix 8
Style: Mk3i
Color: Black
I've worn a Garmin watch for more than a decade, starting with the forerunner 920xt, fenix 5, 6, epix 2. the consolidation of all my health stats and activities in one place and the amount of detail is unmatched by any other tracker I chose the descent because I'm getting into diving. at first I thought the fenix 8 was right for me but the air integration is a must. helps you track your air consumption in much more detail (see the reviews for the descent t2 transmitter) the fenix 8 is also limited to recreational depths, and if you remotely think you might want to get into tec diving or deeper depths, you need the descent as someone who also tracks all runs, bike rides, hikes, workouts etc, the descent is the closest thing to the perfect daily companion the only minor downside is that the screen is not quite as large as dedicated high end dive computers like the shearwaters, but all the functionality is there

Informative
Style: Mk3i
Color: Black
The watch is great. Has so many features I’ll probably never use. But the diving portion paired with the t2 was exactly what I was looking for.

Great for groups
Style: Mk3i
Color: French Gray
Great dive computer. Pros.: GPS; Haptic; Integrated air; Transmitter with no valve; Messages with other divers; Share info with other divers (essential for my, I dive with my family). Cons.: The "sonar" used to communicate does an annoying sound. I prefer my Sheerwater Teric screen customization, maybe I just didn't find the right screen mode. The GPS doesn't automatically input the dive location.
