JBL's Sea Vine Floatline is constructed of hi-tech, durable, thermal polymer extruded shell and a braided 600lb Dacron core. The new Sea vine II is the ultimate fish taming floatline. The .050” wall allows for 100% stretch with optimum memory resistance. Fish can run but they can’t hide. No more extra baggage fees due to heavy, low tech bungees. The Seavine II has landed 200+ lb. tuna in Panama, 100+ grouper in Mexico and 70 lb. wahoo in the Gulf. This line comes with stainless tuna clips with terminal tackle rings and swivels take the guess-work out of landing big game fish.
