This invention is regarding the construction of a new spear-gun to be used for hunting underwater. It includes a set of innovations for enabling easier movement on the horizontal axis, having less recoil, loading by leg power and disengaging without frightening the prey. The invention particularly focuses on the construction of the speargun to provide a low recoil thanks to its horizontal rollers located on its tip, which inverts the direction of the force created by the bands. The projectile, pulled by the shaft cords, accelerates in the counter direction. |
