Product Description

From ultra-light to big game, Hi-Seas Grand Slam Monofilament line is up to the challenge! Its formulation provides high impact strength, excellent abrasion resistance and superior knot strength. It’s equally at home on conventional and spinning tackle. Every yard is computer checked for consistent diameter and breaking strength to provide you with an unequaled level of performance – performance you can rely on. That’s why we say with confidence – Grand Slam is BIG FISH TOUGH!

  • Ideal control and sensitivity
  • High knot strength
  • Resistant to abrasions

Grand Slam Mono Pro Angler Tips

  • Excellent for top water line because it floats and has a low sink rate
  • Great spinnerbait line around shallow cover, and good for buzzbait
  • An excellent “maintenance line” – useful all around, when cover, visibility and/or feel isn’t an issue
  • Good line for slow moving top water baits in clear water, like walking lures and poppers
