I have had analog gauges read high and low(!). One student entered the 
water for a beach dive with an _indicated_ tank pressure of approx. 2250 
psi. During the course of the 30 min dive the indicated pressure rose! 
He 'turned' the dive, commenting that he wanted to get out of the water 
before the burst disk let go! His speech was a little slured, due to his 
tounge being planted firmly in his cheek.

Obviously this was due to the needle 'sticking' on the way up.
