Bait-Tech Halibut Marine Pellets are a high-protein, high-oil pellet designed as a big fish bait, with a proven track record in the specimen world while also working well for smaller commercial carp or river barbel. Packed with high-leakage attractants, they release slowly into the swim, and their slow breakdown keeps attraction levels high over longer periods, making them a popular choice on many top waters. The pellets are available in standard form in 3mm, 4mm, 6mm and 10mm, and pre-drilled in 8mm, 12mm, 16mm and 20mm for easy hair rigging.
