Sculpin imitation is very realistic.
Its width is much greater than height, whereby bait is perfectly fixed on double hook. Sfish 2" is a shad with small tail paddle. At low speed passing it practically does not swinging, but with speed increase it shows powerful, tough high-frequency tail swinging. Hard to say the reason, but bait has magical influence on zander. However, it is a good for other fishes catching, especially for perch.
Sculpin is quite massive and compact, so it attracts big fish and provides far cast, especially on jointed rigs.
