Advanced Weight Loading System (A.W.L.S.)
TUSA's patented Advanced Weight Loading System (A.W.L.S.) allows the diver to insert weight into both left and right weight cartridges eliminating the need for a weight belt. Rear trim pockets combine with the A.W.L.S. to optimally balance the weight load on each TUSA integrated BC jacket.

Independent Harness System
The Independent Harness System isolates the BC jacket's harness from the air cell, tightly supporting the tank even with changes in air cell inflation/deflation. The I.H.S. prevents tank slippage and eliminates any gaps between the tank and your back.

RiteTite Buckle
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.

Ultimate Stabilizing Harness (U.S.H.)
TUSA's Ultimate Stabilizing Harness completely eliminates tank roll and delivers an amazing fit. The U.S.H. 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.

Waist Support System (W.S.S.)
The Waist Support System significantly enhances comfort and fit by dispersing the weight load around the hips. 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.
