Abstract: In a crossbow an elongated casing is connected at one end with a bowstring trigger release mechanism. A pair of bowstring interconnected wings are pivotally connected to the other end of the casing with the wings being normally biased forwardly in aligned position transversely of the casing by a compression spring within the casing moving a flexible element entrained around arcuate portions of the wings longitudinally of the casing. Toggle linkage, contained by the casings, bears against one end of the compression spring to increase its article projecting potential following intital cocking of the bowstring.

Abstract: An elongated tube, adapted to be longitudinally supported by a spear gun, or the like, is provided with a transparent transverse partition at its forward end portion for preventing water entering the major portion of the tube when its forward end portion is immersed. A battery powered lamp, secured by a bracket within the water excluded end portion of the tube, illuminates a target through the transparent partition. A sight area, scored on the transparent partition, visually indicates when the gun is aligned with the target.
