Loon Biostrike Mix - Fluo Pink / Fluo Yellow Indicator Putty
Loon Biostrike Mix is a high-quality indicator putty designed to quickly and easily add visibility to nymph rigs, leaders, and fly lines. The combination of fluorescent colours Fluo Pink / Fluo Yellow provides excellent visibility in different light conditions.
The lightweight floating formula can be used as a small visual indicator on leaders or lines without affecting the natural movement of the flies. The putty is easy to apply, remove, and adjust according to specific fishing conditions.
Loon Biostrike is an excellent choice for nymph fishing when additional visual control is required, especially during subtle takes or in low-visibility conditions.
