Jim, That's not it -- they just dont understand that its not needed. They dont understand partial pressures, they dont understand that you dont need a hypoxix mix for a 250 fsw dive, you don't need convoluted buffonery. It's just one more piece of junk on an already overweight rig. Now if you want to step it up a stroke notch -- check out all of the "remote isolators" that are typically found with the pony. regards, jds At 05:37 PM 8/16/1999 -0400, Jim Cobb wrote: >Bill- > >I think that the main rational on using the travel air pony is to >"conserve" your backgas trimix so you will have enough left to do a air >top for the next dive.
