The Cayman standard barrel is manufactured in heat treated anodized anti-corrosive aluminum and features an integrated shaft guide with an external diameter of 28mm. This speargun handle is new, featuring ergonomic and mechanically innovative characteristics. The triggering mechanism is highly sensitive and extremely resistant to the traction of the slings. When grabbing the handle, the position of the hand is high in relation to the shaft, allowing quick aiming and great absorption of recoil.
