The gold standard in pole spears, our one-piece models are drawn 6063, annealed for extra rigidity. The end result: maximum energy transfer with virtually no flex. JBL Spear Poles are machine-swaged for enhanced hydrodynamics. This provides greater speed with minimal water disruption. Sling length is fully adjustable and the stainless threaded tip will accept any 6mm (7 if specified) point.
