    • Great Multi-Purpose Device
Style: Mk3 Color: Fog Gray
This is a great dive computer if you want a device that you can also use for activities other than diving. It is bright and very readable under water, and you can customize the different screens to suit your needs. My main complaint is that you have to remember to manually start a “dive” activity if you want it to capture your GPS coordinates before the dive, and I haven’t been able to get it to capture the coordinates at the end of dives (perhaps I just need to hold it out of the water or set the end dive delay for longer so that it ends when I’m back on the boat). If you start a dive without manually selecting the activity, the watch will automatically go into dive mode… it just won’t have gotten the GPS position beforehand. Your data syncs to the Garmin Dive app, which is okay but could be better. Annoyingly, it seems to save data to the cloud, not to your device, so you need an internet connection to view your dive log. As an out-of-water watch, it’s a little bulky but not out of line with Garmin’s higher end sports watches. I’ve used it for walking, running, swimming, and sleep tracking. It comes with regular length straps for normal wear as well as a longer strap for diving, and it’s really easy to snap them on and off to change between the two. Garmin also offers a large line up of different colors and styles. It’s relatively easy to customize the watch face designs and add / remove data. Battery life is respectable. ... show more

    • High-Performance Dive Watch with Unmatched Versatility and Safety Features
Style: Mk3i Color: Black Titanium
Review Image by Terry Terry
Review Image by Terry Terry
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

    • 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!

    • 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

    • 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
