It might be interesting to look at the failure rate of air integrated dive computers when they were first introduced and compare that to the current failure rate. We must remember that this is a relatively new technology here. You know, this whole thing reminds me of when the scuba industry first went from dead reckoning available air to the "J" valve reserve system to the submersible pressure gauge. Seems to me that there was an outcry concerning the reliability of the SPG and that it was a new and un-necessary piece of equipment. Maybe history is about to repeat itself. :~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~:~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~: :Patrick Murphy : murphy@un*.sl*.un*.co* : :Unisys, Government Systems Division : "A common mistake that people make : :McLean, VA : when trying to design something com- : :(703) 847-2545 : pletely foolproof is to underestimate: : Opinions expressed are mine alone : the ingenuity of complete fools." : ~~~~~~~~~~~~~~~~~~~The score: Opinions-3 A**holes-1~~~~~~~Douglas Adams~~~~~
