Designed for large powerful fish in open water JBL's Gulf Slip Tip break-away is 3" (76 mm) in length and comes with 6 mm threaded bushing slip-tip configuration in hardened 17-4 stainless and features a multi-braid stainless cable in 3/32" (2.38 mm) diameter. The tip's rear fixed barbs cause the point to turn sideways after entering the fish so it will hang on no matter how hard the fight while minimizing damage to your spear shaft. The low-profile, Tri-Cut point, double barbed design allows for pinpoint accuracy and dependable deployment. Due to the attached cable removal of the spear point is made easier. Tip is available for 3/8" (9.5 mm) and 5/16" (8 mm) shafts in 6 mm threads. Don't trust a once in a lifetime fish to anything else.
