The main two shafts are made of aluminum as well as the fittings. The 3-prong head is a screw on 3/8" aluminum hole fitting with spring steel for its prongs. Heavier and slower in the water than a graphite spear, but packs a bigger punch on impact.
These 3-prong graphite spears breakdown into 3 parts; a removable 3-prong head, middle extension, and end extension with black rubber tubing. This set also comes with a storage bag.
It is highly recommended to half twist the rubber while pulling it towards the head of the spear. This helps to avoid damage to the shaft and better accuracy
