Abstract
A band-powered speargun has a release mechanism incorporating a line-drop feature for releasing a coiled line attached to a spear. An approach to attaching the line to the spear involves a linking ring having a size selected so that the ring passes over a protective cone near the spear tip and is captured by an element protruding outward from the spear shaft. The protective cone also shields hinged barbs from impact damage. The gun may also incorporate a muzzle kill spike and a separate hand-held kill spike that is normally stored in a specially designed cavity in the speargun grip.
