Screw Ball Indicators are easily used with either smaller diameter tippets or large tapered leaders. Their screw on and off design makes it really easy to adjust depth without kinking your line. Screw Ball indicators cast easy and do not twist your leader. This is our #1 choice for a fixed indicator for fishing flies up to 9 feet under the surface.
The large size will hold up even the largest flies like the balanced Minnows and is also good in low light conditions or really rough days.
