Scootering the bottle causes much less drag if placed as low on the tanks as possible. If it is sticking up level with the necks or higher, it slows you dowm. This is all relative - every fpm counts over a long distance. Even not having to stop to change stage bottles adds an effective 20 fpm , something that takes about 5 more pounds of thrust to equal, or a big reduction in drag, as in the difference between a drysuit and a wetsuit. The difference of five pounds of thrust is the difference between one of my scooters and a stock Mako. If I wind a motor for five more pounds of thrust than that, if draws 10 more amps of current, which cuts the burn time almost in half. This shows you how important efficiency and drag can be over distance, as proved by the usdct at Wakulla. Their longest penetration ( by the two Brits - the other strokes could not get to first base) took over five hours to do what we did in 185 minutes, and we were on open circuit, and had to change stages - seven times, and we pulled them all out with us. When we do that same dive on the Halcyon, where there is no changing stages and we are not pulling a bunch of bottles, we cover that portion of the dive in 120 minutes. Of course we are not preoccupied with staying alive , we are enjoying the cave. Doing it their way is like being blindfolded bareass in a box of rattlesnakes. We don't so this to save on deco - we do it to save face. Only a stroke would ride around in a cave looking like a train wreck . Actually , the quicker and more consistently you do it, the safer it is. Charles Ayash wrote: > > I have just over 20 dives with the Halcyon Argon straps > and they work just fine.
