Hi all, just would like to start a discussion on the stability of using the above captioned for diving twins.
IMHO, when twins are attached to a backplate, you basically have 2 air-tanks bolted to the backplate's centre channel. On some designs, the sides of the backplate does not come in contact with both air-tanks. The backplate sides are only in contact with the diver's back. When a diver is horizontal in perfect trim, this results in the air-tanks being lifted off the diver's back, forcing a balancing act as the air-tanks are only being supported by the centre channel via the tank bands.
In contrast, when a diving harness(eg. DiveRite Transpac, Oxycheq A-pac, OMS IQ pack) is attached to twin tanks for diving, both tanks are in direct contact with or resting on the diver's back on both sides all the time.(This will only occur when both shoulder straps, waist band and crotch are tightened and adjusted properly) Now wouldn't it seem that a diving harness is more stable?
It's like riding on a motorcycle(backplates) vs driving a car(Diving harness) & I think that there's no doubt that a car has better stability & balance over the motorcycle.
My way of thinking may be going against the widely accepted views that a backplate is more stable over a harness. But I would like to see if there's anyone out there that share the same view as me.
