Speargun Projectile Assembly.
Abstract
A projectile assembly for use in a breech loading hydraulic speargun. The assembly consists of a dart connected to a plug end. The assembly is inserted into the breech end of the speargun barrel with the plug end sealing the breech end of the barrel. A trigger mechanism on the speargun releases water under pressure into the barrel at the location of the connection between the dart and the plug. The dart separates from the plug and is ejected out the muzzle end of the barrel. A lanyard is attached between the plug remaining in the barrel and the dart and the lanyard is payed out through the barrel as the dart travels to its target. The plug end is removable from the barrel and is made buoyant for convenient retrieval of the dart.
