ABSTRACT:
A lanyard retainer for use in a breech loading hydraulic speargun. A projectile is attached to the retainer and the retainer and projectile are inserted into the breech end of the speargun barrel with the retainer 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 projectile and the retainer. The projectile separates from the retainer and is ejected out the muzzle end of the barrel while the retainer remains in the barrel. The retainer has a forward spindle portion about which a lanyard is wound. The rear portion of the retainer serves as the breech seal and the shoulder between the spindle and the rear portion prevents the lanyard from unwinding onto the rear portion and helps to prevent operator entanglement with the lanyard. The lanyard is attached between the retainer and the projectile such that the lanyard is payed out through the barrel as the projectile travels to its target. The retainer is removable from the barrel and is made buoyant for convenient retrieval of the projectile.
