Amazing!

I adore theis watch

I wanted to focus on motivation to get healthier because I occasionally dive. I used the watch for two dives, and it worked flawlessly both times. Above all, it has aided me in recognizing negative behaviors that were severely impairing the quality of my sleep. It is also excellent for tracking the fitness activities I engage in. Satisfied with the purchase.

Amazing innovation for the Mk2

After I upgraded from the Mk1 to the Ml2, I got this when it was launched. The screen improvement is fantastic, and the problem with inadvertent button presses has been resolved.

An excellent dive computer packed with functions.

I adore this item! The manual's lack of sufficient explanation for its many functions is my sole complaint. Prior to diving, make sure not to click on any features as this could result in a 24-hour lockout from free dive mode (gauge). When all is said and done, it outperforms the Apple Watch Ultra in every aspect save text and call functionality.

It never disappoints

I consistently discover excellent options and great discounts. For years, I had purchased all of my diving equipment from Garmin. I only have positive things to say about their products and services.
