New cuttlefish shape speargun with considerable mass and rigidity featuring an integrated Enclosed Track spearshaft guide. This system features three principle advantages; it keeps the shaft exiting the gun perfectly strait during the shooting phase even with double bands avoiding any possibility of so called “shaft whip”. The absence of recoil induced energy loss confers more power to the spear. Less energy is dispersed through recoil which is a typical phenomenon on open track guns. The shaft is no longer susceptible to lateral vibrations while maneuvering the gun. The outcome is more power, accuracy and range than traditional open track guns of comparable size., , The increased volume of the speargun barrel allows for an optimal balance of the gun even with 7mm shafts and double bands. This creates an agile speargun which is easily maneuverable even in the longest sizes. Cayman E.T. CAMU: The camouflage version differs from the stock version with a three-dimensional camouflage speargun barrel using «heat-transfer» technology. It includes a Match 30 reel in the 75cm and 85cm sizes and a Match 50 on the longer sizes.
