If divers are using the pony as an excuse to dive longer or for penetration than they have to go back to one of the even earlier concepts of air supply management, ie the old days rule of thirds...I know, I know, now with gas, its not thirds, but the concept is still the same....coming up on the boat with 500PSI is not a good thing.... Just cause we are carrying all this air does not mean we use it all up....a big chunk of it is meant to be a safety reserve and if you dont get that you shouldnt be putting your head underwater.... Redundancy is a vital conceptual thread that needs to run through all of ones diving.....equipment, planning, air supply....and here we go back again to time spent underwater....until someone has built up time underwater they will not get the profound need to respect very basic safety measures..... I agree totally that after a certain point in wreck diving everyone should be in doubles. Somewhere along the place where deco begins and definitely once folks begin thinking about any kind of penetration. But I really hate seeing people come out with single tanks and octopus.....it seems to me that a pony there is a huge safety factor...not thought of as 'oh boy, more bottom time' but simply a safety factor....a redundant air supply for when Murphy comes knocking...... -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
