The JBL 200 Series Speargun Bands are durable, and specially designed to withstand sun damage for less frequent replacement. The unique latex formula and dip manufacturing process provides modulus strength. As the spear band is stretched the power curve increases, offering top notch performance. The 302 stainless wire spear wishbone is extra tough against your spear shaft. This speargun band measures 9/16" x 20" and fits the Explorer 22 and Sawed Off Speargun models.
