Billy, I use an analogue watch with depth and bottom time as my backup. The watch has a large second hand which can be use as a stand-in stop watch. cheers frank ----- Original Message ----- From: <billy@v3*.co*.au*> To: <techdiver@aquanaut.com> Sent: Wednesday, March 07, 2001 8:13 AM Subject: Re: Underwater timers.

Unfortunately, both of these timers only count in full minute increments. My deco program (Abyss RBGM) has 30 second intervals on it's deco stops. When I mean stopwatch, I mean just that. Something that I could start/stop and reset for each stop. This would be in addition to my bottom timer, not to replace it. >Deco stops are kind of boring and an idle mind has lots of room to wander while hanging there. Consider this: If you dive a 240fsw dive for 25 minutes, you will have 17 deco stops. If you ascend at 30fpm it would take you 20 seconds to arrive at your next stop. If you do not take this into account, then you would shorten your total recommended deco time by about 6 minutes (17stops X 0.33minutes=5.661 minutes). This is silly. Stop confusing yourself. Use run-time. rdgs billyw -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
