IT's been an issue for a while....
I was diving with a buddy of mine a few years back and he was using an "air integrated" dive comp - the type that has a transponder that you fix to a spare port on the tank regulator - as we were exiting the water another pair were going in, one of whom had an identical model computer to my mate.
As we passed each other both computers beeped as the transponders switch between the divers... so the guy coming out suddenly thought he had a full tank, and the guy going in appeared to have not much above 50bar left (i.e emergency reserves). This was reported to Suunto and the reply back was its a 40000 to 1 chance so would do nothing about it.
