Spearfishing is an exciting adventure sport which involves shooting fish underwater using a spear gun. It is a perfect way to bond with nature and enjoy the beauty of the aquatic world. However, there are different terms that refer to spear guns. Among them are harpoon guns, tridents, and underwater guns. Harpoon guns are designed for hunting large marine animals, while tridents are used for close-range fishing. On the other hand, an underwater gun is often used by experienced spearfishers who want power and accuracy when hunting. Regardless of the name used, spear guns are a must-have tool for a memorable spearfishing adventure.
