DIY Strike Indicators

Well, after having a heck of a time trying to do a decent chironomid presentation without using any indicator, I decided that its time to try.

First decision, what to use?
Strike indicators come in a variety of forms… from clumps of yarn to balsa or cork floats to glow-in-the-dark putty’s.

Apparently putty’s can stain your fly lines, so I think I’ll avoid them for now. Balsa or cork floats seem a little heavy duty for the presentation I’m looking for, and might make it a little more difficult to detect a subtle hit.

Okay…so yarn it is. Well, not so fast…there are a few varieties there, so I thought let’s be cheap. Can I make my own? A quick Google and I had the answer. And there are still a lot of ways of doing it.

For my indicators, I used the following materials:

  • I picked up a couple packages of Rug yarn…its a synthetic yarn that is precut into 2.5″ strips. For a larger hook presentation, these might end up being a little small, but I think that for fishing with chironomids, they’ll be just fine. I suppose adding a couple extra strands and some floatant will help as well.
  • small elastic band (on my first version)
  • black tying thread
  • green heatshrink
make your own strike indicators

My first indicator (bottom right in the picture below) I initially tried by simply wrapping the loop with thread, as described over at flyfisherman.com, a bit of thread and heatshrink to create the loop, but I wasn’t happy with the finished product. After seeing the method described over at the GFF site, I went out and picked up a pack of 7/16″ O-rings, and passed the yarn through the O-ring, folded the yarn in half, then bound it with thread. Pretty simple, and I think it will work well. I then soaked the yarn in dry fly floatant.

For the second indicator (bottom left), I used only 3 strands of yarn… 2 green and 1 yellow. And I used thread and heat shrink to bind the yarn together, and then thread to create the loop, and a few drops of head cement, then soaked the yarn in dry fly floatant.

Heres how they turned out (the bottom ones are the home-made models):

commercial and homemade...can you really tell the difference?

The commercial ones are amazingly simple. No tying at all…they just use very small o-rings, and a larger one to fasten the leader to/through. However, a package of 4 was $5.99. The couple that I made cost around 30 cents…and I’m sure that would be even less if I can find a better source for the O-rings. The ones I used were 7/16″ Moen replacements, for about $1.20/pkg of 4.

Here’s how the indicators are attached to your line:

    Things to try:

    adding a bit of teflon plumbers tape to protect the yarn in the o-ring where it is fastened to your leader
    smaller o-rings – all I could find were 7/16", would like 5/16", and also some 1/8 or 3/16" (if they come that small) – ideas anyone?

    Ray,

    Where did you get the rug yarn from? I’m having trouble finding it.

    Thanks,

    Jeff

    Thanks for the article. I found some #5 3/8″ OD x 1/4″ ID x 1/16″ O-rings at Home Despot 10/$2.50 USD on my way to Lees Ferry. They worked great. I used fluorescent egg yarn. You need to waste a lot of expensive floatant with this yarn so I will seek out some poly yarn. You don’t need two sizes of O-ring and this small size makes for a tight fit around the line so it doesn’t slip. There is a commercial product made this same way:

    BTW the “poly” that floats is polypropylene, not polyester. Very important since polypropylene is the only yarn whose density is less than that of water.
