Spear fishing gun

Spear fishing gun (speargun), a tool used by divers for underwater hunting, powered by rubber bands or pneumatic systems.

About this subject

The speargun is a mechanical device that launches a spear to capture fish underwater. Its basic principle involves storing elastic or pneumatic energy to propel the projectile accurately. The most common versions use rubber bands that, when stretched and released, fire the spear. Pneumatic models use compressed air for force.

The modern speargun's history dates back to the 1940s when French divers like Georges Beuchat and Yves le Prieur began developing more efficient equipment. Previously, spearfishing was done with hand spears, as used by indigenous peoples. In Brazil, the practice is regulated by Ibama and requires a license, popular along coastal areas like São Paulo, Rio de Janeiro, and the Northeast.

Model choice depends on the environment: wooden or aluminum spearguns are preferred for clear waters and larger fish, while carbon models offer lightness for long dives. The spear tip can be fixed or rotating, and a retention line prevents losing the fish. Safety is crucial: the gun should never be loaded out of water, and the trigger finger must stay off until the shot.

Interestingly, spearfishing with a speargun is not only a sport but also a tool for controlling invasive species like the lionfish in the Caribbean and Atlantic. In Brazil, the lionfish (Pterois volitans) is targeted in removal campaigns, and divers use spearguns to capture them.
