One of the biggest drawbacks to the Descent G1 is that it is not air-integrated. This is a marked contrast to what can be found in the older Mk2 models. But despite the lack of air integration, the sheer amount of profiles available in the app that cover a wide range of gas choices is very impressive. You can either choose to do a standard descent or rapid descent for the more technically advanced. There is also a range of features that allow for easier dives when you are hunting quarry, such as the apnea feature that allows you to set everything to vibrate. The Descent G1 is a more affordable dive watch, but it does come with a strong wave of diving innovation as well.
