Loon Biostrike Indicator Putty

Product Code
Loon Biostrike Indicator Putty 2 5 5 1

BioStrike is a putty indicator that makes adjusting the depth and size of indicator simple.

  • Biostrike floats high and will not become waterlogged, or come off during vigorous false casting.
  • It is also reusable, biodegradable and environmentally friendly
  • It is the perfect indicator when fishing small flies that are difficult to see.
  • It can be used nymph fishing or fishing small dry flies.
  • Biostrike is so sensitive that it can detect the subtlest of strikes and lands softly, so it will not spook fish.
  • 50/50 colour combination tub of pink and yellow.

How To Use: Wet fingers and pinch desired amount. Form in to football shape and apply to the line. When done, put back in the container and reuse again.
