Garmin does it again
I have quite a few Garmin products: cycling computer, radar, and newest to the quiver: the Descent G2 Dive watch. I am new to diving - and having something reliable for autonomous adventures is very important. The functionality of this watch underwater surpasses expectations and I feel confident knowing that it's a reliable, accurate and easy to use watch when it matters most. It uses the same readiness score from other products (using heart rate and HRV) to provide a dive readiness score that is helpful in decision making. You can fully customize this watch and set it and forget it. I plan on getting a lot of mileage with this dive watch and am grateful to be armed with everything I need to descend and ascend safely.

Underwhelming
In all honesty I bought this because I wanted an upgraded dive computer but this offered features like my cheap Fitbit. While I haven’t had a chance to use it for diving, I wish now I would have spent half the money for a dive computer and just kept my Fitbit. It is what it is but I will not recommend buying this if you want to keep track of your fitness.

Ok so far
Still getting used to the G2. Will go on first dive later this month. Meanwhile, I've looked for a way to allow text messages to come through, but no other outside media like Facebook or Emails. No luck so far.
Great watch decent dive computer
So I have only had this for like a week or so. Only used it so far in a pool doing skills refresher. Can't wait to use it shortly on a "teal" dive.
Great first Dive Computer / Watch
This is the first dive computer I have ever had. It covers most of the basics that you want in a dive computer for the price.
