Rubbers-gun for underwater fishing

Abstract

Rubbers-gun for underwater fishing, comprising a shaft provided at the front with a head and at the rear with a body with a grip and provided with means for retaining and releasing a spear in which the shaft of the gun is made of polyamide reinforced with glass fibres by means of a gas injection moulding process. The cross-section profile of the shaft of the gun is rhomboid, tapered from the centre towards the two ends. The gun also comprises a reel connected to the said body by means that permit an initial positioning of it horizontally to the said shaft, therefore with the axis of rotation substantially perpendicular to the shaft, and a second positioning inclined at a certain angle compared with the said shaft.
