All you need is one gun! Most spear divers bought a reef and bluewater gun but one ended up in the closet never being used often enough. This is our game changer! Saves money and world resources (SDG goals).

Change your barrel instead of buying an entire gun! This means, you can purchase one gun and adapt the barrel.

You already have 90% of the parts! The more options you buy the cheaper the gun gets.
