The Harpoon Launcher is one of the weapons in ARK: Survival Evolved. It is used to fire 
Spear Bolts and 
Tranq Spear Bolts.
It is a very effective weapon for underwater combat and for knocking out sea creatures. However, its not a viable weapon on land, as the projectiles will not travel very far.
- After firing bolts, it is possible to pick them back up (if they don't break).
- The Harpoon Launcher has a much higher range when fired underwater.
- This item doesn't appear to be part of any supply beacons. This means that they can only be primitive and end up being outperformed by high-quality crossbows, which are cheaper and more efficient.
