The Elite spear gun range from JBL features their revolutionary M8, 3 piece trigger mechanism. Its compound leverage design and 1?4\u201d stainless components make it the strongest mechanism in the world and provide shooters with smooth, effortless trigger pull. The ergonomic design and hex pattern on the handle increases grip control and accuracy and you have the option between mahogany or teak wood for the handle. All Elites feature 17-4 stainless shafts, shark fin style tabs and top flopper with 5\/16\u201d thread. You can shoot Tahitian-style or remove the flopper and screw on a break-away tip for large game fish.
