The tubing has a reduced inner diameter (ID) of 1/16" this means the hole is smaller than conventional speargun tubing. All other speargun band tubing comes with 1/8" inner diameter.
Speardiver small hole rubber tubing next to conventional 1/8" ID tubing.
Why this format was chosen
- Quality speargun rubber tubing is made of Latex/natural rubber, which comes from the sap of the rubber tree. Latex in its natural color Amber is less resistant to sunlight. An outer layer of black dyed Latex adds UV protection and extends the life and performance of the band.
- Cut a band after a day of spearfishing and you'll see water come out of the hole. The cycles of stretching and compression draw water into the band no matter how well you tie the wishbone, and it remains trapped there. Salt water damages the band from the inside, you can see this layer of deteriorated rubber immediately around the hole of a well used band. The small 1/16" hole significantly lessens water intrusion into the band, improving performance and increasing longevity.
- Less hole equals more rubber at the same diameter, which equals more power without increasing the profile of your speargun.
