The BC-0101 Liberator Sigma II Buoyancy Compensator is a heavy-duty, wrap-around jacket Style BC that utilizes TUSA's Advanced Weight Loading System and Ultimate Stabilizing Harness, which ensures security and stability. With its two large, double zippered pockets with mesh drainage, you can maximize utility and function. TUSA's Advanced Weight Loading System (AWLS) allows the diver to insert weights into the weight-cartridges and loading them easily into the front of the BC jacket. Additionally, with weight distribution to the shoulder area, the weighted-down feeling that is traditionally associated with weight belts is eliminated. Weight cartridges can accommodate from 8 lbs. (3.63 kg) to 10 lbs. (4.54 kg) of weight in each cartridge and two rear trim pockets can hold up to 4 lbs. (2 kg) in each non-releasable pocket. The AWLS weight cartridges are easy to release in an emergency, but the safety lock makes sure that they do not release accidentally.
The key to comfort with the Liberator Sigma II BCD is its Independent Harness System (IHS). The IHS isolates the BC jacket's harness from the air cell, tightly supporting the tank even with changes in air cell inflation/deflation. The IHS prevents tank slippage and eliminates any gaps between the tank and your back. The Liberator Sigma II BCD uses TUSA's next generation IHS featuring an Integrated-Carry-Handle, additional adjustability to dial in a perfect fit and a neutrally buoyant construction allowing the diver to shed the lead removing approximately 2 lbs. (1 kg) of lead from their system. TUSA's Ultimate Stabilizing Harness (USH) completely-eliminates tank roll and delivers an amazing fit. The USH securely holds the air cylinder in place with optimally placed rails and brings the tank closer to the body increasing tank control while reducing weight.
The RITETITE buckle is a 2-position cam strap for quick and easy adjustment. While the strap is being looped through the buckle, the buckle stays in place without needing to be held. This allows for more control and stability. This feature is part of all TUSA BCJ's. The BCD has an adjustable sternum strap for maximum comfort. The W.S.S. integrates the adjustable shoulder harness system with the rear stabilizing plate and cummerbund to effectively unload the hips while ensuring a snug fit. BCD is made from durable 500-Cordura nylon with an internal urethane laminated air cell. BCD has, 2-large zippered pockets for storage of accessories. Torso adjustable shoulder straps provide excellent comfort and adjustable waist strap with cummerbund provides precise adjustment of harness. All straps are equipped with squeeze-style" side-release buckles for easy donning and doffing. Buoyancy is controlled by TUSA's patented O.P.E.V. Quick inflate/Deflate System. Trimming buoyancy is easy with 2-dump/overpressure relief valves. BCD provides 18 lbs. to 46 lbs. (8.16 kg to 20.9 kg) of lift depending on the BCD size. Accessory attachment is made easy with 1-stainless-steel D-ring and 4-resin D-rings. BCD comes with an owner's manual and a 3/8" threaded low-pressure (LP) hose.
