  • 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

  • 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!
