On the tek trip I did to Truk on the Agressor we did a different wreck every day for seven days, two dives a day, to depths that would be described here as being in trimix range. Sometimes followed by a night dive. If you're going to provide gas for this kind of trip you're going to have to double your estimate. The wrecks vary in size from large to really large and if you're planning to do trimix bounce dives on a single tank you're not going to see much. Then you really would be just wasting your time and money. You would be better off just doing the sport range stuff. Sport divers on the "Thorfin" were doing as many as seven dives a day. They'd be seeing a lot more and getting more out of their trip at a lot less expense and effort than some single tank trimix bounce divers. If you're going to go to all the time and expense of sending helium to Chuuk you might as well send a ton and do the tek wrecks right or you really are just wasting you're time. ajmarve@ba*.ne* wrote: > well that assumes all 14 dives require helium, and i am now hearing that only a couple > of the dives are this deep, so if anything i need to revise my estimate downward, which > just makes the final dollar figure even lower. > > if you want to go hand to hand with the list on why independents are stupidity, be my > guest. i will not be diving such a rig in the immediate future< like, ever.>. > > in any event, why on earth would you need double 80's for a non penetrating dive in near > perfect conditions? are we not diving in a buddy team? are we doing extreme exposures in > middle of Pacific, 14 hours from a chamber? 15 to 20 min bottom times would lead to a > runtime compatible with backgas deco w a single 80. bring a 40 of 50/50 to deco and you > should be able to stay w/in thirds for chirstsake. > > you know the more i think about this, the more reasons i see to not dive this site with > these people, who obviously have little regard for anything besides the money people pay > them. > > perhaps if the checks had to clear customs at the airport before they got paid they > could figure it out. > > Al Marvelli > > I would bring my own manifold. > > conversely what type of brain disfunction does one have to have to need two 80's > > Scott Stitt wrote: > > > Al > > Your math looks reasonable enough except for one possible problem.
