The invention relates to a speargun equipped with a system for improving performance and ergonomics. The essence of the invention is a system for stopping the contraction of the rubber bands on the lower side of the speargun in roller and inverted roller spearguns. The rubber bands are stopped by a stopping element positioned on the lower side of the speargun. In addition to this stopping element, the stopping of the rubber bands is also facilitated by a connecting element that links the left and right rubber bands, forming a loop that catches onto the stopping element, thereby preventing further contraction of the rubber bands.
