Review Summary

If you do not have a dive computer and if you do not have a smartwatch, MK2 is hands down the way to go. The amount of features and options is incredible. The watch screen is less than perfect on the surface in my opinion. However, underwater the screen is fantastic. On the other hand, if you already have a smartwatch and are only looking at buying a dive computer, I would suggest Shearwater Teric might be a better option. There is no better screen in dive computers today. Period. Four-button navigation is extremely intuitive. Teric also provides more dive information. Teric, however, does not have GPS capability. Bottom line, if you want an all-in-one dive computer, get the Garmin. If you a looking for the best dive computer, give Teric a look.

Love my Garmin MK2i. I use it for everything skiing, rowing, running and of course diving. Easy to use, battery life is great as well. The only negative I might say would be that it is a little big for smaller wrists, but it is a computer with a lot of functions. I would definitely recommend to anyone who does more than diving.
