Roller Spearguns

Roller spearguns are a specialized speargun type which utilize a special roller muzzle to propel the speargun rubber bands. The attractiveness of roller spearguns is due to the unique design they utilize greater band retraction to gain additional power and shooting distance. Typical band spearguns only utilize 2/3 of the potential band retraction capacity, where as roller bands utilize 100%.. Being able to hunt waters with a shorter gun and still have the shooting range of a speargun of larger size is appealing to many divers. A properly setup roller gun has little to no kick as the retraction of the bands in both directions cancel each other out and increase accuracy.
