D-100 The D100 is a dual bladder tech-wing for divers requiring redundancy. The bladder is equipped with ClamRetract™ for greater volume increases and superior deflation capabilities, whilst six dump valves and two inflators with a mechanism in stainless steel makes sure that air can be inflated and deflated in a controlled and safe manner. The shape of the bladder compensates for the weight of the tank when submersed as well as giving complete freedom to move in any direction. The air passage behind the neck is narrow enough to avoid pushing the head forward or interfering with the regulator and hoses when inflated. The D100 has a wing contour which facilitates the use of double tanks - it has a greater distance between the wing legs - and the system is made for equipment with a negative weight in water that does not exceed 32 kg (70,5 lbs), with a lifting capacity of 353 N. A double, non-flex tank band is delivered with the BESEA D100 which can also be equipped with integrated weight pockets, accessory pockets, metal back plate, Q.M.R.-system™ Pinbolt kit and D-rings. 100 lbs dual bladder tech-wing Inflator with a mechanism in stainless steel Non-flex tank-band Equipped with the ClamRetract system.
