This is a really cool indicator and super sensitive. It is perfect for super selective fish using smaller nymphs in shallow water. The coils will provide a little stretch so the fish will not feel tension on the take, allowing you time to set the hook before the fish spits it out. Extremely easy to see.
We like to add this to a 7 ½ - 2x leader and for smaller streams, a 9’-2X leader for medium sized streams and a 12’ 3X leader for large Western rivers. Just connect the leader to the indicator via loop-to-loop and then add a section of 5X, 6X or 7X tippet two and 1/2 times the depth of the water you are planning to fish. As a general rule, this section including the dropper tag needs to be at a minimum 5 feet from the coiled sighter to fish effectively.
It is best if you will rig the flies off of dropper tags like you do with Czech nymphs. This will enable the flies to move around freely in the water. This indicator is also great for Stillwater. Just grease the coils with a silicone paste like Mucilin and it will float on the surface. When a fish takes your fly, this indicator will start to stretch out and the fish has no idea that he has eaten your fly. Simply lift the rod and set the hook. This indicator is super fun to fish and very interactive!
