Rubber bands are the “engine” of the speargun. That’s why Andrianblue trusts Sigal Sub’s EXTREME series for such an important part of its wooden spearguns. Very high contraction speed and 1.5mm internal hole will give you what you need for a quick shot.
Available in 14.5mm, 16mm, 17.5mm and 19mm. The first choice for the most demanding spearos who leave nothing to chance.
