What's in the box: Spear Shaft
This JBL shaft is for the Magnum JBL450 and JBL4D50 Spear Guns. The JBL756S is 56" (1,422 mm) long with a 3/8" (9.5 mm) diameter and 6 mm threads. Having spare parts for your gun or sling is the only way to assure you won't get skunked on a spear fishing trip. Constructed of corrosion resistant 17-4 (spring) stainless each shaft is hand-tuned for alignment then heat-treated for maximum hardness to reduce flex and provide optimum energy transfer. Spear Shaft has a 3 Sling Capacity and makes a great Save-A-Dive Kit item.
