damageddiver:It has been said that checking your computer into an un-pressurized compartment for a long period of time can damage the accuracy of the depth gauge?
Where would you find anywhere unpressurised ? Certainly no modern aircraft runs like that unless its broken in which case the health of your computer will be the last thing on your mind.
Short of sticking your depth gauge in a vacuum chamber for the hell of it i cant see a problem.
