Nothing breaks the surface as the indicator dot drifts downstream past a holding fish — then it simply vanishes with no ring at all: the take was already in your hand.
The drift slides evenly — then the sighter checks. That stall IS the rise. Below the surface the delay disappears: anything unnatural, tighten.
Takes you feel
Takes you feel
Below the surface the rules invert: the subtler the signal, the faster you respond — anything unnatural, tighten.
You'll see
Nothing — that's the point. The take arrives as a stab or stall on the sighter, a dip of the indicator or dry, a draw as the wets swing round, a tap-tap on the stripped lure, or the line simply going heavy.
What it means
A fish has the fly RIGHT NOW and is already deciding to spit it. A drifting nymph should travel like the current: any check, stutter, slow-down or sideways slide of sighter, line or leader is either the bottom or a mouth — and you treat both the same.
The flies to answer with
How to fish it
Nymphs under a sighter or dry: strike everything
Sighter checks, stalls, slides; the duo dry dips or drags — lift NOW, short and firm. It costs one drift to check; it costs the fish to wait. This is the exact opposite of the dry-fly delay.
Wets on the swing: let it draw
Downstream swing takes hook themselves as the fish turns — resist the snatch, let the draw build, then firm up. Upstream spiders invert again: takes are a faint check of the line tip — lift promptly but gently.
The induced lift
At the end of a dead drift, lift the flies slowly — the nymph 'hatching' towards the surface pulls decisive takes you feel as a solid pull. End of drift is prime time, not packing-up time.
Streamers and fry: strip-strike
Taps and nips are the fish testing — keep stripping, change speed. On the solid hit, strike with the LINE hand (or a short rod-side sweep), never the full upward dry-fly strike: a missed strip-strike leaves the fly fishing; a missed trout-set ends the cast.
When to strike
Strike everything, instantly
Subsurface, the delay disappears: anything unnatural, tighten immediately. Only the swung wet earns patience — let the draw develop before you firm up.
The strike clock →Easily misread
Waiting on a nymph take
The sighter checks, you count your LoughLogic — and lift into nothing, every time.
Instead: The delay is a DRY-FLY rule, for watching a fish close its mouth on the surface. Subsurface you're already late: strike the instant anything looks wrong.
"That's just the bottom"
Checks get rationalised away; half of them were fish.
Instead: You can't tell — so you never try. Set on everything. The bottom costs a recast; the assumption costs fish all day.
When you'll see it
- Euro-nymphing riffles and pockets — the sighter is the rise
- Duo/klink-and-dink drifts — watch the dry like a hawk
- Swinging wets and spiders down a stream; pulling lures on the lough
