A Refined Line for the All-Around Trout Angler

The Scientific Anglers Frequency Trout GP is built for anglers who demand finesse without sacrificing versatility. Borrowing its belly taper from the famed Infinity but with a slightly longer front and rear taper, this line delivers graceful presentations while maintaining enough backbone for a wide variety of trout scenarios. Quarter-size heavy for easier loading yet tuned for precision, it’s the perfect match for anglers who favor dry flies, nymphs, and light rigs over bulky streamers.
