Cobra 3 sucks?

I've never had any problems with mine after 3 years and hundreds of dives. I do however have a problem with DM5 software "Where is the thank size setting and start and end pressures"?

Regarding the Cobra 3 compass, it's important to do the calibration. In my experience the only way I could get the compass to calibrate was to set the computer on a wooden table and rotate it there; if I tried to do the calibration while holding it in my hand and turning around, it would never work as it would presumably tilt too much in my hands while rotating it around.
