When I said: > On really deep > bounce dives (where the distance between bottom and first deco stop is on > the order of 150-200 feet), change it to 2/3 instead of 1/2, and add a > third one. I meant change it to *1/3* instead of 1/2., and make the third deep stop 1/2 the distance from the 2nd deep stop to the first deco stop. I.e., Bottom is 220, first "required" stop is 40: hang out at 160 for a minute or two (220-40=180, 180/3=60; 220-60=160), then again at 120 for a minute or two (160-40=120, 120/3=40; 160-40=120), then again at 80 for a minute or two (120-40=80, 80/2=40; 120-40=80), then go on out and finish your decompression schedule. If you're worried about the extra ongassing on the deep stops, then extend your 20 and 10-foot stops by 20%. If you're using a computer (which you shouldn't be unless you're diving a Cis-Lunar or Oceanic rebreather, because there are no other computers available that account for Helium, and you shouldn't be doing a 220' dive without helium), then stay at least 20 feet deeper than the computer's ceiling, and don't ascend above 20 until the computer clears. This advice applies ONLY to deep bounce dives, where the distance between the bottom and the first deco stop is very large. I would recommend other things for different profiles. The following still applies: > If you get bent, don't sue me because it's your own damn > fault for diving in the first place. If you don't get bent, send me > monetary gifts for your appreciation.
