So whats the real difference?

[7ftDiver]

I am a new diver and am purchasing my first set of gear. I am trying to decide on what type of computer to get. I live in the north east so alot of my diving will be in this area. My question is "what is the difference between the air interated computers and the non-air intergrated units. I know the simple things like more accurate pressure and air time left. But other than that is there a real difference? any help is appreciated. thanks in advance

When it's working, the air integrated computer tells you how much pressure is left in your tank. The non air integrated computer or the air integrated computer that has failed has no way of knowing that information

air-integrated means that the computer keeps track of how much air you have
used and projects how much time you have left

if a computer is not air-integrated, you have to keep track of your air separately
via a pressure gauge.

you pay more for an air-integrated computer.

personally, i can keep track of my air just fine with a pressure gauge, so i use
a cheap (Aeris Atmos 2) computer that does everything i need it to do.
