This is a classic situation of divers doing something on single tanks that they should not have been doing. Through no coercion on my part, these divers realized that there is a better way and figured it out, all by themselves, that the pony stuff had to go. Why are we so behind the times up here? Jim >> DUUUU_UUUUUUH, Everyone, if they stay diving......a good if......evolves from pony to doubles.......EVERYONE IF THEY STAY DIVING........and also, do not forget that many of the concepts that are taken for granted today simply hadnt been worked out yet six years ago...... all of us have done that .......no one is saying that doubles are the inferior product......simply that the reality of people diving with singles needs to be recognized and up here in open ocean conditions and diving on wrecks often in not great vis, a pony as a completely redundant, emergency only, air source is a valuble tool.... This argument that the single 80 on its own is perfectly adequate should,, SHOULD, the diver pay proper attention to air consumption and never get totally hung up somewhere and never have an equipment failure or never have to aid someone else... and that thousands of dives are conducted like this all the time, so why bother.... well, its kinda like me always taking my tanks back to the shop with 1500-2000 pounds in them and being busted by the fill guys..... That air or gas is there for me for the time that I or someone else is in some kind of trouble and am going to need it...... Most thankfully it hasnt happend yet, but on that day that it does, I will have a margin of time to hopefully be able to cope with whatever Murphy and Posiedon choose to throw at me.... This life can all to easily be extingushed through not enough air, so why shouldnt I carry it with me..... -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
