Two huge features stood out to me when I picked up the Petrel. 1) The AA battery option makes my save-a-dive kit much easier to maintain. I use rechargeable AA’s which further decreases my cost of having to replace. 2) The 1000 hour memory is amazing. I use this computer for work and play, but being able to record every dive makes sure I am covered and backed up if there are ever any questions or issues with work. Diving with the computer is beautiful and easy. The large and bright screen never leaves me guessing on my air or dc times.
