I recently purchased a Garmin Descent Mk3i diving watch from scubaonline.de. The delivery from Germany to Ireland took 5 days. I use the watch for day-to-day health monitoring, as well as for hiking, running, walking, and diving. The watch is beautiful and stylish, with excellent battery life, and it combines all these features into one device. I am very satisfied with both the product and the customer service.

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.

As many reviews will attest, this is very likely THE ultimate fitness and diving watch combined into one package. The display took some getting used to but is fairly easy to navigate. I have now taken this watch on several small dives in very low-vis conditions and was able to day and night navigate with the depth and compass showing on one screen. I also was able to calculate air as well as NITROX diving calcs and log dives from the app over to a paper log (needed for instructor sign-off). I am still a student finishing Advanced and other certs but thus far, would recommend.

I've owned the Garmin 5x, 6x, 945 LTE and Epix Gen2. I run, hike, downhill ski, cycle and now with my MK3i I dive with my watch plus all these other things. I've used this on 10 dives so far and love it with the air integration. Wearing it all day and night allows my watch to track my dive readiness, sleep, body battery and tissue gas levels during my surface interval. Love this watch. Btw I have worn my Apple Ultra diving and it just doesn't compare.
Awsome bit of kit. Upgraded from the mk2i. Love the Amoled screen. And super nice to wear. Miles better than the mk2i. Very much in love with my purchase.
I do a lot of other activities besides Scuba diving so I decided I wanted to have a smart watch which is also a dive computer. I did a lot of research watching reviews on YouTube before I decided to invest in the Garmin MK3i. I also waited for the 51mm version to be released as the bigger screen would suit my diving a lot more than the 43mm.On receiving the smart watch the screen is looks big but also looks the part especially with the titanium strap. My boss and work colleague have the garmin watches but were so impressed when I showed them the MK3i with its functions that my work colleague is looking at buying one.It has so many functions which I am slowing learning how to use them.

I also like the garmin dive app which downloaded onto my smart phone when I linked them both together. The coloured maps on the watch look good and the light on it is quite handy.I’ve not used it for diving yet but cannot wait to try it when I’m in the Philippines in March.
I purchased the Garmin Mk3i in January for a dive trip on Maui. As a dive watch it worked flawlessly. It was one less thing not having to worry about. I didn't use the air integration yet. I have used Garmin pay and it works perfectly. I have used many of the other apps and they work well. I have yet to use many of the other features but I'm anticipating worrying free use. There is a steep learning curve to master all of the features of this watch and there are plenty of great tutorials and support if needed.
Does everything I hoped for and more. Surprisingly easy to use, brilliantly clear and informative watch faces, clear and readable even at 30m. Added bonus of multisports providing huge amounts of data for my running. Connects to apps perfectly and Aquanauts were brilliant.
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.
I bought this watch back in February after having the MK1 for 4 years and never having an issue. In March I was in a bad accident while on a motorcycle and the watch survived with a dented watch band bar and a couple small dents on the bezel. All other functions of the watch are still perfect, the screen isn’t even scratched, and with Garmin’s amazing warranty program they replaced the watch bands and bars for free. This watch is a tank and I recommend it to anybody
