Whether you are replacing a tired canister or upgrading your O2ptima, this one gives you flexibility. It accepts the Extendair cartridge for quick, consistent swaps, or you can pack it with loose granular absorbent when that is what you have on hand or prefer to dive. Having both options in one canister means you are never stuck because the shop at your destination only carries one type. A straightforward, genuine Dive Rite part for keeping your rebreather in the water.
