Loon Biostrike Putty Loon Outdoors produces its very popular Biostrike Floating Putty, a great alternative to carrying multiple sizes of indicators as you can adjust the size and amount of putty for the perfect size indicator. One of the most useful putty colors is the glow-in-the-dark for when you are night fishing with dry flies or nymphs. Often you have to guess when fish take in the dark but using a small dab of bio-glow a few feet above your fly will give you a visual cue without adding a lot of weight to your leader.
