For divers who use argon gas for drysuit inflation or carry a small bottle of spare air, our Argon Bottle Mount carries one 6-cubic foot or one 13-cubic foot tank. Designed to attach along 1-inch (2.54 cm) D-rings of the TransPac backplate or along perimeter holes of aluminum or steel backplates, the Argon Bottle Mount can be attached to either side of the backplate and behind the diver"s arm. A quick release buckle allows the bottle to be removed, if necessary, during a dive.
