Garmin Descent Mk2, Watch-Style Dive Computer, Multisport Training/Smart Features, Stainless Steel with Black Band, 010-02132-00

Worth it for the wireless air tracking! Garmin always has a great product and it’s so easy to use!

I bought 2 units for wife and I after seeing a guy rave about one on a January Jamaica diving week...We switched out from Mares Puck Pro units which had 200+ dives and no problems (1 needed battery replacement which I did). the Mares unit is very simple and accurate although we wanted something sexier and with non diving features. The Garmin Descent MK2i is a beast...It takes lots of practice to use it correctly and even figure it out as I have the Manual pdf open lots of times to learn something new or what I messed up...I dont have much to say about non-diving performance except it is Garmin and what more is needed to day?...We use as fit bits and tracking our sleep, heart rate, etc. Now for diving - We have 23 dives in St. Lucia at depths 15-115 on single gas with the T1 transmitter on both units (so dual tank readings). We love the feature of seeing your buddys air at all times and alleviates need to keep checking, plus buddy watches out for you if you focus on something else. We set these for conservative and always do a 15 safety stop for 3 minutes before surfacing. Head to head with the Mares unit they were essentially identical; Garmin is more precise in adding decimals for temperature and exact psi compared to the tank valve version, although same. We ran decompression stops on several dives and both units (actually all 4 - 2 Mares + 2 Garmin) and data was the same. We enjoy the Garmin many ways to view dive on changing the screens during the dive. Backscreen illumination is decent although not bright enough in darkness (a small cave in daytime), Id use my light anyway so no big deal. The transmitter sound is audible although not annoying and Ill see about tuning it down a bit although I may loose range. A feature I dont like is the short battery life when diving...Yeah, I know about taking off Wifi, bluetooth, functions etc, but why have to bother just for diving or anything else. I found we ran batteries to 50% after 1-1.5 days and needed to use to primitive alligator clip charger plug. We used both dive computers all week and I am not ready to go to just Garmin. After dive my tank pressure was hard to screen back to after exiting water, Mares much simpler in that one button push gave surface interval vs. garmin that needed several buttons pushed to get to the S.I. screen. At this point we like the sexy Garmin as it looks nice and we can change the watch face, changes screens and move stuff around. the sapphire crystal did not scratch and sustained several knocks against the boat and coral with no damage. The weakness in the system is the T1 transmitter that is fragile and cannot be used to lift tank (OK I got that) BUT...after wrench tightening it would loosen up after several dives and susceptible to accidentally touching or jostling it and it got loose. Garmin should give you a flat wrench of correct size for tightening as the standard wrenches dont work on the tank to transmitter distance. This is a best/worst feature with T1 - love safety issue of joint knowledge of tank pressures, dont like fragile/ease to loosen. A feature that I may not have correct now is the wifi and bluetooth communications between watch/dive computer and iPhone/computer...perhaps because we staying NoData/Airplane mode when out of the US as were were in St. Lucia. We will keep the Garmin units and work toward becoming better users...They did a good job trying to work in the dive computer...for just diving get something else (Sherwood)...if you are a workout enthusiast and love to have lots of data/stats to work with..this is your unit. Ill update this review as we get more data - lots of diving coming up..

This thing is absolutely amazing! Enormous battery life and collects data for days. The features aren’t super intuitive but after a few hours of messing around with it you are able to really zero in on how you want your watch to operate for you. It has a very large face which may look strange but it wears very well and is nice for ease of data viewed. I’m a very sensitive sleeper and I don’t even notice it’s on while sleeping. So far I’m blown away.

I’ve had my MK2i for a few months and logged 16 dives with it. The dive app with AI is amazing for logging your dives and showing a timeline of PSI per minute, depth over time, HR, pulse Ox, and water temp. It genuinely helps you be a better diver by keeping your head in the game on descent rates, ascent rates and NDL easily displayed and easily navigated. I’m a new diver with the money to spend on gear that will last a long time so I see many years of use out of this watch and transmitter and couldn’t be happier. I was on the fence because of the price but so happy I pulled the trigger.

I loved the watch, I used it on a few dives and it did great. However, the Start button fell off randomly.... Not sure how the button on the outside just fell off, but when paying this much for the watch, id expect a little better craftsmanship.

My dive buddy got the Mk2i just two weeks ago because he knew I had just gotten a Shearwater Teric.

I love the watch. I’m not getting the advertised battery life but it is still way longer than my old Apple Watch. I have only used it on two dives so far but the watch worked great and the dive app has some nice features.

I was an early adopter of the Mk1 and reliably used that for >100 dives. I also had a Fenix 6 as I loved the new features of that. This is the perfect blend. It is also amazing looking and does not feel as large or heavy as specs are due to the materials and ergonomics.

La batería dura muchísimo, el uso del reloj es muy intuitivo, las aplicaciones están increíbles y la resolución de la pantalla muy buena. Las aplicaciones de buceo y buceo sin tanque (Apnea) son bastante precisas. Además de ser un excelente computador de buceo las demás apps como golf, correr, bici, etc. Cumplen con la precisión necesaria de cada una de ellas.
