A.W.L.S. (Advanced Weight Loading System)
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.

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.

Independent Harness System (I.H.S.)
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.

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.


Service and Repair (BCJ)

Q: Can I get replacement AWLS pockets for my BCJ?
Yes, replacement Velcro and mechanical AWLS integrated weight pockets are available, please contact your TUSA authorized retailer.

Q: My BCJ bladder is leaking air or has been punctured, can it be patched?
Your BCJ will have to be evaluated to determine if the size and location of the puncture can be repaired. Please contact your local authorized TUSA retailer.

Q: What is the proper care and maintenance of my BC?
Rinse the outside and inside of the BCJ with warm fresh water thoroughly to stop the formation of salt crystals on vital components. This should be done as soon as possible post-dive and prior to allowing your BCJ to dry. Once rinsed, line dry completely and store partially inflated in a cool dry place away from heat, electric motors and other sources of ozone. To maintain the BCJ, annual service/inspection by an Authorized TUSA retailer is required. This is also a prerequisite to retain the warranty.
