BUKU wind-on leaders are attached with a quick and super strong ?oop to loop?connection system. Wind-on leaders are fantastic for game fishing. These special leaders allow for a smooth wind in through the guides for easier handling and release of fish. Please check IGFA rules online before fishing for any updates or changes to regulations to ensure your record catch meets requirements. IGFA - Leader Length is measured from the connection point (loop) to the bend of the last hook. IGFA - Saltwater over 10kg* - max length of leader is 30 feet. Saltwater 10kg* and under - max length is 15 feet. IGFA - Freshwater all classes - max length 15 feet. * Refers to the test strength of angler? main line, not leader. Please note: If using a double to connect to the leader different measurements apply. Refer to IGFA rules for total length of leader, double and rig combined.
