<p>The invention relates to an underwater hunting gun of the crossbow type with an effortless string-drawing device and low recoil. The gun uses push-rods (15) intended to tension elastic links (8). The push-rods (15) are placed laterally on a moving headpiece (11) activated by a lever-operated arming system (10). The elastic links (8) run freely around the push-rods (15) in such a way that the front ends of the elastic links are permanently and preferably fixed to the base (18) and the rear ends are fixed under no tension in a slot (17) of a bolt or arrow (3). The sliding of the moving headpiece (11) in the forward bolt-support segment (2) intensifies the drawing of the elastic links (8) from the back forwards over and under the push-rods (15) thus optimizing, at the time of firing, the range of the bolt (3) without any recoil of the crossbow through the fact that the bolt (3) is expelled in the manner of a whiplash. The crossbow incorporates a power regulator and an arrow rail offering stealthy firing suited to the range to the target.</p> |
