It’s enough to consider that target shooters underwater use spear shafts without barbs to improve accuracy. With this easy to install accessory, you not only increase penetration but accuracy as well. Just a lip on the barb of the shaft can affect accuracy on a long shot, specifically with a big clunky barb that does not have the best aerodynamic shape.
1. Insert the shaft cone in the front of the shaft and warm with a hair dryer.
2. Apply a small amount of acrylic glue just a moment before sliding down the cone
3. Hold the cone with a pair of pliers and slide it down on the shaft with force.
4. Let it sit in position while the glue dries
5. Use after three hours
