Copper John

Tungsten nymph searcher
Trout · GraylingSubsurface

Slim nymph with copper bead head and fine body — a searching nymph that works on any river with a hatch happening. Copper beads have become standard for a reason.

Fish this when

Spring and autumn when small mayfly nymphs are hatching. Fish it upstream in broken water on a tight line or with a small indicator.

Why it works

Slim profile suggests small nymphs. Copper bead adds visibility and gets the fly to the right depth fast. Simple, proven pattern.
