Sighter
Also called Euro sighter, sighter section, bi-color sighter
A sighter is a short, high-visibility section built into a leader, used to track drift and detect strikes by watching the leader instead of a floating indicator.

What Sighter means
In tight-line nymphing, the sighter sits between the thicker leader butt and the thinner tippet. It is usually made from brightly colored monofilament, or alternating colors, so small hesitations and direction changes show up.
You fish it with the rod high and the line mostly off the water. The goal is a straight, lightly tensioned connection from rod tip to flies. The sighter is not meant to float, it is meant to be seen.
Some anglers build sighters as a dedicated section in a Euro nymphing leader. Others add a short “indicator” section to a standard leader when they want visual feedback without a bobber-style strike indicator.
Why it matters on the water
A sighter gives feedback when the flies are out of sight and you are not relying on feel alone. If it stalls, twitches, jumps, or starts moving faster than the current seam you are tracking, that is a cue to set the hook or adjust weight.
It also shows whether the rig is leading or lagging. When the sighter stays in the same lane as the current you are targeting, you are usually closer to a controlled drift. When it bows downstream or sweeps across lanes, you are dragging or losing contact and need to change rod angle, mend less, or adjust weight and tippet length.

- Euro nymphingA tight-line nymphing method that uses a long rod, a thin leader with a sighter, and weighted nymphs to keep direct contact through the drift.
- LeaderThe leader is the clear, tapered line between the fly line and the fly. It turns the fly over and gives you a clean, controlled presentation.
- Strike indicatorA strike indicator is a small float or marker on the leader that shows takes and depth while nymphing. It moves, stalls, dips, or shoots sideways when the flies get bumped or eaten.
- TippetTippet is the thin, level line tied to the end of your leader. It’s the section you cut back and replace as you change flies and re-tie knots.
