violating a deco ceiling (bending the computer) may result in it 'locking up' for 24 hrs or something stupid like that, so it can't be used for repetitive dives -- pain in the ass ss ----- Original Message ----- From: <tgunther@co*.co*> To: Jarrod Jablonski <JJ@gu*.co*> Cc: Kevin Connell <kevin@nw*.co*>; <ben@wi*.co*>; <techdiver@aquanaut.com>; <quest@gu*.co*>; <trey@ne*.co*> Sent: Tuesday, February 29, 2000 2:36 PM Subject: Re: computers? 1 depth gauge, 2 time keepers, your mother in law... > << Below is a quick Bakers on computers.
