US12372324 - Modular hybrid speargun

A system for underwater hunting contains a plurality of components which allow for customization of the speargun based on the user's needs and the conditions where a user is hunting. By allowing rapid additions or removals of certain components, the invention allow the user to easily modify the firing characteristics of the speargun, and thus target a wider range of prey across a wider range of environmental conditions than those designs currently available in the prior art.

The patent describes a modular speargun system that allows users to customize the weapon’s components, including barrel length and ballast units, to adapt to various hunting conditions. This innovation enhances the speargun’s versatility, enabling users to target a broader range of prey effectively.

Claim 1

A speargun, comprising: a barrel removably inserted within a stock allowing for barrels of varying lengths to be utilized, a spear, the stock featuring a left side and a right side, each of said right side and said left side of the stock configured to receive a ballast unit, the ballast unit comprising at least one hydrodynamic ballast wing configured to be removably and directly attached to at least one of the right side and the left side of the stock such that the hydrodynamic ballast wing extends laterally from the stock and allows a user to increase or decrease an overall buoyancy of the speargun during use, a handle connected to the stock, a trigger housed within the handle, said trigger containing a mechanism for releasing the spear when activated, and a means for propelling the spear when the trigger is activated. a barrel removably inserted within a stock allowing for barrels of varying lengths to be utilized, a spear, the stock featuring a left side and a right side, each of said right side and said left side of the stock configured to receive a ballast unit, the ballast unit comprising at least one hydrodynamic ballast wing configured to be removably and directly attached to at least one of the right side and the left side of the stock such that the hydrodynamic ballast wing extends laterally from the stock and allows a user to increase or decrease an overall buoyancy of the speargun during use, a handle connected to the stock, a trigger housed within the handle, said trigger containing a mechanism for releasing the spear when activated, and a means for propelling the spear when the trigger is activated.
