Randy, the point of balancing the rig for the dive is lost on this
discussion. With aluminum and a wetuit, the weight should be removeable,
as in a weightbelt, so that one can get up in a bad situation. The point
of "simplicity" lies in not complictating the rig with multiple bc's,
and therefor adding more problems while trying to solve a self-inflicted
problem (using the wrong tanks).
We ( WKPP) do NOT use integrated weight nor do we use steel backplates
with almuminum when diving wet in the ocean. If we are using a drysuit
and aluminum, then the integrated v weight and the steel plate can ofset
the suit, but then the problem is that if you take the tanks off in the
water to clip off to a tag line in rough weather, they are at risk of
being lost. I would rather lose a weightbelt.
Steel should only be used with a drysuit, but then steel on a boat is a
problem walking around in rough weather and for the reason mentioned
above, and is totally unnecessary . The extra gas in 104's for instance,
is only equal to one more aluminum 80. Take a stage bottle if more gas
is needed, but then what kind of moron is going to incur that kind of
decompression liability in the open ocean? I can see taking a stage and
doing the whole dive on the stage , preserving the backgas for emergency
and or for more dives, but if not to offset hoovery or excessive
exposure - neither is too smart.
Aluminum doubles are negative 6 full of air, roughly half of that with
50% helium, positive 6 empty. The weightbelt used depends on the
person's overall buoyancy and on whether or not that person is using a
droppable canister light ( itself usually 6 pounds negative in salt
water).
The total rig should be balanced for the full range of gas use, and
should solve all of its problems wiht a flick or the wrist, so to speak.
Only the worst irrepsonsible idiot would allow diving with a wetsuit and
steel in the ocean, and I can attest to the body searches for those who
have . This is right up there with the bottle marking stupidity that we
see out there being taught and instituionalized. Same idiots, different
stupidity.
I hope you are reading our web page wrong, if not, I will correct it. My
bet is you are following some link. I can not be responsible for the
pesonal preference or other insanity that springs up on other people's
web sites.
