Set of 5 high visibility strike indicators made of yarn and o-rings. They can be trimmed down to a smaller size if you prefer. Yarn indicators are designed to land lighter on the water than other styles of strike indicators to limit the spooking of fish. No knot needed so less stress on your tippet line. Add floatant as needed to keep your indicator floating high. Set includes Tippet Rings: Ten 2mm 25 pound and Ten 2.5mm 40 pound, each size on individual swivel clasp rings for easy identification between the 2 sizes. To attach to leader, first isolate the next ring in line to be removed before opening clasp. Tie on leader to the ring before opening clasp. Next open clasp to remove ring. Close clasp to lock in remaining rings. These rings are small in size so as to float when dry file fishing or sink when nymph fishing and to be less visible to the fish. Rings eliminate the need to cut back on leader. Ideal for attaching two different size lines. Rings are black nickel in color made of a strong Alloy. Product comes packaged in a Fly Fishermans all-time favorite round cup with hinged lid.
