As a fly-fishing guide, I teach clients to fish nymphs under an indicator much of the year. A constant challenge is how to eliminate micro-drag from the leader without having to constantly remind the clients to mend. The double indicator system has helped my clients see and understand when it’s time to mend, resulting in better drifts and more fish in the net.
The principle is very simple. Take your favorite indicator rig, and pinch a very small amount of Loon Biostrike, or an Orvis Stick-On Oval Indicator on the leader about 12 to 16 inches above your standard indicator (toward the fly line).
This “upper indicator” tells you when it is time to mend. During a drift, the upper indicator should always stay upstream of the lower indicator. When the upper indicator begins to float parallel to or downstream of the lower indicator, it’s time to mend the line to put the upper indicator back upstream. This will eliminate the micro-drag of the leader that can often kill a dead drift. The nice thing about Biostrike and Stick-On foam indicators is that they are brightly colored, so it doesn’t take very much to be able to see it well.
Hopefully you find this double indicator rig useful as a teaching tool. Use it if you’re having trouble knowing when to mend, or if you think you might be getting micro-drag. Once you get used to identifying drag on your leader, you will fool and land more trout.
