i had a problem with mine a few days ago.....a bunched of fudged numbers and it was 1000ft off on the ride to altitude
last week. thank god i noticed....i always cross check my audible with the altimeter on my wrist. then it just showed a bunch of weird numbers and stuff. i took the batteries out......after only 40 jumps and put new ones in to no avail....still the screwy numbers. was getting ready to send it back and wham.......started working perfect and no problems since the for the money its not bad......would love a pro-track...but i only have 125 jumps and will stick with what works.
