Loon Outdoors Bio-Strike is a putty indicator that makes adjusting the depth and size of indicator simple. Beyond that, it is reusable, biodegradable, and environmentally friendly. BioStrike can be rolled in a ball with wet fingers and applied anywhere on a leader, then removed and placed back in the container.
Wet fingers and remove Biostrike from container; the amount depends on the weight of the flies being fished. Roll Biostrike into a football shape and apply to leader at desired depth. After fishing for the day, remove Biostrike from leader and return to container.
