On these real short dives you are not hitting it too hard anyway, but the correct answer is that the break regimen is taken for granted in all of my deco posts since they speed deco and make the process work, as well as make it safer and prevent damage, so I do not specifically mention them in the general schedules. As the dives get longer or more days of diving are done back to back, then you have to start making a point of it. Notice what I said to Ted Green on his second four Doria dives about starting the 50% gas ten feet shallower and starting the oxygen 2 feet shallower and splitting it into decreasing depth increments above 18 feet. If you look closely at what I say, all of the tricks are there. -----Original Message----- From: dir@po*.co* [mailto:dir@po*.co*] Sent: Monday, February 18, 2002 4:30 AM To: trey@ne*.co* Cc: scuba@md*.co*; trey@ne*.co*; techdiver@aquanaut.com Subject: Re: 220-250 foot diveRE: Andrea Doria Deco Dive would there be any time on the 30' stop breaking to backgas prior to the O2?
