  • 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. ... show more

  • 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.

  • Exceeded my expectations when I upgraded from a MK1
Style: Mk3i Color: Black Titanium
I’ve had a Mk1 which has served me well. This watch has a bigger, brighter screen, and so many more features. Wear it scuba, golf (excellent) and road biking. Best is the morning health report!

  • 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. ... show more

  • 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 ... show more

  • Just wow!
Style: Mk3i Color: Black
The media could not be loaded. For my very first smartwatch I am 100% confident I chose correctly. This thing has soo much built into it, it's gonna take me a good week to learn it. Taking it diving Sunday. The brightness and color screen alone will outshine my vyper novo. Also picked up the T2 sonar transceiver, I feel excited like a kid with a new toy! Will update after I get it wet. Update: this is the best dive computer I have ever used, clear and easy to read under water, vibration for alerts is awesome, alerted me at 1500psi which my other computer did not, clear color notification when safety stop is cleared, alerts when depending or ascending too fast! Man have I been missing out. If you don't own this, you should!!! Also super easy to use, I thought it was gonna be a learning process, but I was wrong, extremely user friendly. ... show more
