A simple piece of Dacron, tied in a barrel, is a visible and sensitive addition to your tight line and euro nymphing rig.

Better yet, it draws your eyes to the colored monofilament of any sighter and enhances visibility threefold. The Backing Barrel adds a third dimension of strike detection, with the Dacron flag just stiff enough to stand away from the line, but just soft enough to twitch upon even the most subtle takes . . .
