Seaguar florocarbon is preferred by professional fishermen the world over for it's ultra low visibility, superior abrasion resistance, tensile and knot strength. Seaguar fluorocarbon does not absorb water like nylon mono leaders and is unaffected by the sun's UV rays. Seaguar is the top choice for all trolling, live lining, chumming and chunking situations. Because fish can't see it, you can use a higher test leader without jeopordizing the natural presentation of the bait. Make the switch from mono leaders to Seaguar Fluorcarbon and watch your "bites" soar. This is a 25 yard spool of 8 lb. leader line.
