About Tusa Liberator Sigma II BCD, Black (BCJ-0101)

The Highly-Anticipated 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 8lbs (3.63kg) to 10lbs (4.54kg) of weight in each Cartridge and two Rear Trim Pockets can hold up to 4lbs (2kg) 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 a Internal Urethane Laminated Air Cell. BCD has, 2-Large Zippered Pockets. 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 18lbs to 46lbs (8.16kg to 20.9kg) 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, 3/8" Threaded Low Pressure (LP) Hose and is covered by a 12 month limited warranty.

    Comments about Tusa Liberator Sigma II BCD, Black (BCJ-0101):

    This is my second BCD. My first was a travel BC, which I was not happy with. I added the APA inflator/deflator to this BC, which takes the whole experience up a notch. The fit was great, and the construction seems very solid. I did 7 dives recently in St Thomas, and I can't imagine ever needing anything more in a BC. I am 5' 10" 195lbs, and the "Large" fits well with room for adjustment up and down depending on level of protection. And of course, LP's pricing and delivery was great, as usual.

      Comments about Tusa Liberator Sigma II BCD, Black (BCJ-0101):

      I bought this as an economical start to outfitting myself with equipment. This is a very comfortable bc that allows for a full range of motion. If I could change one thing, it'd be to make the weight pockets bigger. I only use 3lbs (each side), but a bigger soft weight might not fit.

      Jonathan K  You don't have any info about this BCD. What's the difference between this and the BCJ-3200? Which would you recommend?
      Jonathan K  It seems to me from the photos that the BCJ-0101 has more D-rings and fasteners, or is that just my imagination?
