Sight nymphing is a visual fishery that relies on observation. Unlike a gobble that everyone will see, detecting a fish that is feeding underwater is often the result of careful observation. Once spotted it will be necessary to present it with precision and discretion an artificial which will have to evolve in a natural way at the good depth. The idea is quite similar to dry fishing, but the third dimension (depth) makes the exercise more delicate: you can no longer see your lure, dragging (unnatural drifting) remains the enemy... But now it is invisible. The touch is also very subtle. We base ourselves on the behaviour of the fish to detect the possible catch of the lure (or its refusal).
All in all, it is a fishery where there is rarely any room for the "close call". Success is often the reward of observation and a well-developed technique. It is sometimes necessary to stalk for a long time for finally few line strokes. The first few passes are decisive, there are rarely many attempts on our over-fished public courses. The approach also plays a big role because we fish at relatively short distances.
You have to react quickly both to present the right spot and to strike at the slightest sign of a catch. But when you feel the weight at the other end of the line that lifts the uncertainty, what a pleasure...
In order to practice this type of fishing, where we are mainly looking for trout and grayling, we need blanks that will meet a demanding set of specifications. You have to cast a small nymph quickly and accurately on a long, thin leader. Manoeuvrability plays a role when you have to deploy a long leader in a crowded environment. Although the blank is nervous, it should also be able to hold nice fish on fine to very fine nylon diameters.
