There are a few mountain lakes that I want to explore that are at about 400-500m above sea level.
My dive computer's have altitude settings for diving at altitude;
A0 = sea level to 700m
A1 = 700m to 1500m
A2 = 1500m to 2400m
A3 = 2400m to 3700m
The A0 setting confuses me. If "altitude diving" is diving at heights above 300m then shouldn't A0 = sea level to 300m?
I looks to me like I should leave the computer in A0 for these lakes, But if I do it would just use the normal algorithm for sea level. It would be no different to me diving at 0m then flying straight up to 400m altitude?
Or do my computers (Mares Puk pro and Suunto Octopus 2) have an altimeter that know how high I'm starting from and make corrections? There is nothing in the manuals I could find that indicates that this would be the case and if it was, whats the point of setting the A0,A1,A2,A3?
