This guy made a home made speargun. He uses anything he can find and makes the best of it. A good day of diving is when he sees his feet :D. The fish is called a Snakehead, and are VERY dangerous despite their size. They offten attack without cause and are very protective of their nest. I give cudos to this man, cus their aint no way in hell i would be doing that!
