Time to update my old computer. I'm a recreational diver, mostly warm water but occasionally off coast of SoCal. I haven't done nitrox yet but want the new computer to be able to handle it. Don't want wireless. Looking to spend 400-600 or in that neighborhood. I do maybe 25-30 dives a year. I have been looking at the Aeris Atmos, Oceanic Pro (very similar), and the Zeagel N2ition. I've heard pros and cons about air integrated and don't know if I want AI or not. Oceanic is local, so I can drive to the manufacture for service but don't know how important that really is. I'll take any advice you guys have. Thanks for your help...
