When selecting between different spearguns it's important to first establish weather you want a wood or pipe speargun. While they both can work similarly the handling, weight, and durability can differ between these 2 types of materials.
About Pipe Spearguns
There are hundreds of pipe or hollow tube style spearguns available. Kona Honu Divers tries to select only the best bang for the buck. Barrels are made most commonly of aluminum and are hollow to promote bouyancy. They can be shaped either round (tubular) or oval (cuttlefish).
Why Pipe Spearguns are Better
Typically these guns are lighter and less expensive than wood barreled guns. They can be colored to look like anything with some pretty fancy designs. Some are even coated with extra layers of coating to make them more durable.
The Drawback of Pipe Spearguns
The Downside of a pipe gun is mostly it's durability and behavior when firing. Pipe spearguns are more prone to denting and flooding. Thicker barreled guns will typically be more durable. They are also lighter underwater and so they will recoil more when fired.
