Tim, I mentioned the use of the belt with the drysuit. While taking off the tanks in no way is a good idea in a drysuit, and in no way can compare to having your buddy untangle you, I will say that a belt with a drysuit for standard weighting must be under the harness. I use a little one for "extra" weight so I can add more gas to the suit in cold water. I can also tell you from our experience in caves taking off the tanks to deco ( keep in mind we are on a ceiling and have help from support divers ) that the weight required to keep me and JJ down in C-4 is 24 pounds. On the other hand, when you drop down in a wetsuit , no only does the suit lift go to zero, but your body is compressed in all of its spaces to such a degree that your surface buoyancy numbers are no longer even close - you are much more negative. The steel with wetsuit assholes have not found that out yet ( other than the dead ones ). Your observations about fixed weighting are none the less correct in principle, but for a non application. tim humphrey wrote: > > Steady on George, the name's not Black(or is it Bleak) nor Morin(or is it > Moron)nobody mentioned wetsuits or aluminium tanks: for the record I dive > twin 12's steel and a dry suit.
