These modular ball clips from Solar give you room to experiment with your bite indicator setup. They are made of stainless steel and are compatible with all of Solar’s hanger bodies. The distance between the steel balls is made so that no matter what line you use, they always clamp enough to give bite indications. On a bite, lift your rod up and you can start drifting as usual. The stainless steel makes them a little more durable and for the real tackle freak, they also come in part black to match your setup!
