Wreck diving in the Solomon Islands. Twin Scuba Tanks

In remote areas of the South Pacific, it can be difficult and expensive to obtain quantities of pure oxygen. In addition, the weight limits on commercial aircraft mean that divers have to travel light and leave a lot of gear at home. Airline check-in staff are also very suspicious of 7kg steel pony bottles! The lightweight alternative is to take two regulators (yoke first stage) and stainless steel tank bands.  Two hire tanks can be bolted together and the BCD bolted to the bands.  By attaching a regulator to each tank, you have two independent scuba units. Swapping regulators from time to time ensures that you always have a secondary air supply available. Poseidon regulators can be used left-handed on the second tank because they are never upside down!
