Liberator Sigma II BCD Jacket
The highly anticipated BC-0101 Liberator Sigma II Buoyancy Compensator (BCD) is a heavy-duty wrap-around jacket-style professional diving equipment. Crafted from 500D Cordura nylon (a high-strength and wear-resistant material), the product comes in a classic black color and offers a full range of sizes from XS to XL, catering to the needs of divers with different body types. Integrating TUSA’s patented Advanced Weight Loading System and Ultimate Stabilizing Harness, it ensures both safety and stability; equipped with two large double-zippered pockets and other practical configurations, it maximizes the practicality and functionality during diving, bringing reliable and efficient underwater experience to divers.
Core Feature Highlights
- Ultimate Stabilizing Harness: Completely eliminates tank roll, firmly secures the cylinder through optimally positioned rails, brings the cylinder closer to the body, enhances cylinder control while reducing weight perception, and achieves a snug and comfortable wearing experience.
- Two Large Double-Zippered Pockets: Equipped with mesh drainage design, it combines storage capacity and drainage practicality, allowing convenient storage of diving accessories to meet the storage needs during underwater operations.
- A.W.L.S. (Advanced Weight Loading System): TUSA’s patented technology eliminates the need for a traditional weight belt, enabling divers to load weights into both left and right weight cartridges; combined with rear trim pockets, it achieves precise balanced distribution of weight load and optimizes diving balance.
- Two Dump Valves (OPEV + 1): Features efficient exhaust design, helping divers quickly adjust buoyancy and enhancing the flexibility and safety of underwater buoyancy control.
- Multi-Specification D-Rings: Includes 1 stainless steel D-ring and 4 resin D-rings, which can stably mount various diving equipment such as diving lights and cameras, expanding the scope of application.
- RiteTite Dual-Position Cam Buckle: A quick-adjust dual-position cam strap design; the buckle stays in place without being held during strap threading, enabling convenient and efficient adjustment and improving wearing stability and controllability.
- Full-Size Buoyancy Capacity: Different sizes correspond to precise buoyancy configurations, including XS-18 lbf./8.2 kgf., S-22 lbf./10.2 kgf., M-31 lbf./14.3 kgf., L-38 lbf./17.3 kgf., and XL-46 lbf./21 kgf., which can be accurately matched according to diving needs and body shape.
Core Technical Advantages
1. A.W.L.S. (Advanced Weight Loading System) – Patented Technology
This system allows divers to load weights into both left and right weight cartridges, completely abandoning the use of traditional weight belts. The rear trim pockets work in conjunction with the A.W.L.S. to achieve precise balanced distribution of weight load, ensuring that the weight load of each TUSA integrated jacket-style BCD is in an optimal balanced state, and improving the stability and comfort during diving.
2. Independent Harness System (I.H.S.)
It completely separates the BCD harness from the air cell, and can firmly secure the cylinder even when the air cell volume changes during inflation/deflation. Effectively prevents cylinder slippage and eliminates any gaps between the cylinder and the diver’s back, providing stable back support for divers and enhancing diving safety.
3. Waist Support System (W.S.S.)
By integrating the adjustable shoulder harness system, rear stabilizing plate and wrap-around waistband, it evenly distributes the weight load around the hips, significantly improving wearing comfort and fit. While effectively reducing hip pressure, it ensures a snug fit of the entire equipment and avoids equipment shaking during diving.
4. IR-3 Compatible Design
Compatible with the IR-3 integrated second-stage regulator/power inflator, it expands equipment adaptability and provides divers with more flexible equipment matching options.
