The KOAH Euro OT (open track) is complete and outfitted to take down anything in its reach. Slim, sleek, and weight ballasted this speargun is sure to set the bar in performance. Equipped with a 9/32 poured enclosed track, two 5/8 bands, a reverse trigger mechanism for an additional two inches of band stretch and an aggressive rake (angle) handle to even out the weight of having the entire stock in front of you. The muzzle and side channels were designed to pull the inner band close to the shaft, down the length of the speargun to create lateral band pull which greatly reduces recoil. Guns are measured from the front of the Trigger mechanism to the tip of the muzzle. Total stock (from gun butt to tip of muzzle) is as follows… 90cm , 100cm.
