Pneumatic speargun for spearfishing and method of loading and firing a pneumatic speargun for spearfishing, which speargun comprises a cylinder (1) having a head (10) at its front and a body with a hand grip (11) at its back, having a slide guide (2) for a spear (7) and having a reservoir (3) for a pressurized fluid and a barrel (4) connected with the reservoir (3), a piston (5) being slidingly mounted in said barrel (4), for movement from one or more end loading positions in which it is retained by retaining means, to an end discharge position, triggering means being provided for releasing the retaining means and accordingly causing the piston (5) to move from the selected end loading position to the end discharge position, the piston (5) in the loading position being mechanically connected to the spear (7) such that as the piston (5) moves from the selected end loading position to the end discharge position it causes the spear (5) to be propelled, wherein the piston (5) is removably connected to the spear (7) via a cable (6) and return means, such that the piston (5) is moved from the end discharge position to the selected end loading position by pulling the cable (6). |
