New for 2013, after extensive testing the KOAH Euro is complete and outfitted to take down anything in its reach. Slim, sleek, and lead balanced this speargun is sure to set the bar in performance spearguns. Equipped with 9/32 poured enclosed track , two 5/8 bands, 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 front of Trigger mechanism to tip of muzzle. Total stock (from gun butt to tip of muzzle) is as follows... 100cm has 48" stock, 110cm has 52" stock, 120cm has 56" stock, 130cm has 60" stock and 140cm has 63" stock.
