Notice that all valve knobs are not blocked by hoses or regs so they will be easy to find and manipulate. The right post has two hoses running off of it. 1) Green Protector is the long hose. It is on the turret and can rotate around give an OOA diver maximum hose length. 2) Blue Protector is the BC inflator. The left post has 3 hoses running off of it. 1) Blue Protector is dry suit inflator. (Until Argon) 2) Big Black protector is the short hose. The hose is angled to take up extra slack until it is needed. 3) Little Black protector is the HP guage. Guage clips onto left hip Dring.
