I was trying to say that some computers allow you to select the ambient pressure to be displayed in either fresh- or seawater calibration.

Ah, gotcha. Ok.

Totally agreed. These two threads are really just all mental mastu....uhh, better stop there....got Jocelyn Elders in trouble.

Didn't make any sense to me. Can anyone explain?
