These Wing BCDs with Double Tank design are ideal for those divers who want to be sure that they will have excellent buoyancy control. This bladder provides one-way air flow between the two tanks and reduces the risk of a diver losing his/her trim while switching tanks. The 50lb double tank also provides excellent buoyancy compensation, as well as support. Inside this bladder is a 420D nylon inner bladder and 1050D Cordura Outer Shell. This strong and durable donut bladder twin tank measures 16x15x11 inches.
The Wing BCDs for Double Tank/Twin Cylinders is evocative, to say the least, but that's why you're drawn to it in the first place.
