TUSA Liberator Sigma II BCD with IR3

TUSA Liberator Sigma II BCD

A heavy duty, wrap around jacket style BC.

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. 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.


  • Ultimate stabilizing harness
  • 2 large double zippered pockets
  • A.W.L.S. Advanced Weight Loading System
  • 2 dump valves (OPEV + 1)
  • 1 stainless steel and 4 resin D-rings
  • 500D cordura nylon
  • Quick inflate/deflate system
TUSA IR-3 Duo-Air Alternate Inflation Regulator

A downstream backup regulator that also provides you with easy to operate buoyancy control.

The IR-3 is positioned at the end of the buoyancy compensator hose, the ideal location for quick, efficient use. Because you use it as your power inflator, you always know where it's located (that's a priceless advantage in an emergency). Plus, the IR-3 cuts down on hose clutter because the same hose is used to supply both the power inflator and the backup regulator. The regulator features a dependable downstream demand valve mechanism.


  • Combination of octopus regulator and power inflator
  • Classic downstream regulator valve
  • Air balanced power inflator valve
  • Single hose configuration
  • Nitrox compatible to 40%
  • Inflator integrated secondary air source
  • Increased safety in out of air emergencies
  • Self flushing mechanism
  • One button purge function
