The next generation of Shearwater Research’s industry leading dive computers, the Perdix AI is smaller with longer battery life.  The Perdix AI represents the latest evolution of the “powerful, simple, reliable” concepts introduced in the Predator, and further refined through the Petrel 1, Petrel 2 and Perdix. 
For those familiar with Shearwater computers the interface and program will be familiar, now housed in a much slimmer body (30% smaller volume than the Petrel), and greater battery life (up to 30% longer with AA Alkaline than the Petrel 2).
