As a few have mentioned already, the Apollo Bio Tank Lock Band is a real quality product like everything else from Apollo Sports. If you have any sort of difficulty at all with conventional tank straps, the Bio Lock might very well be the answer for you. Its worth giving it a try. We have a divemaster here at the shop that uses them on a Dive Rite Transpac, and i know for sure that he wouldn't use anything else. It is a very quick process to cinch the tank down tight with the Bio Lock, and its not going anywhere once its locked in.
