I cannot say enough good stuff about the new Shearwater Perdix AI (Air Integrated) Dive Computer. Not only is this the best dive computer made today, but Shearwater is a company that is dedicated to diving, and the dive community. I have been diving Shearwater computers since they made their first model, the Pursuit. 

When I teach technical dive classes, in the classroom we download our dives from my Perdix AI to the Shearwater Dive Log, and look at the particulars of dive. This makes the Perdix AI an incredibly valuable learning tool, not just in my classroom, but for any diver with a laptop or desktop computer. This is also why I strongly recommend that students use a Shearwater computer, at least for class. 

The limiting factors we have to deal with while planning or executing any dive are the decompression, oxygen, and gas supply. With the Perdix AI, all of this data is available for post dive review, in detail.

As far as the Shearwater company itself, they are dedicated to helping divers better understand diving. On their website, they regularly post informative cutting edge articles written by knowledgeable experts. New articles are announced in the Newsletter, and I strongly recommend that you sign up, even if you are not diving a Shearwater. They also have YouTube videos, to help you get the most out of your dive computer. 

These are a few of the Shearwater articles, and a video that I personally like.
