The Smith D-Contact 5cm can fish "hollow" where other lures won't.
Its animation consists in bringing it back in a linear but jerky way (small scion strokes) or working it up and down (waterfalls, rocky bars, low walls) rod high, a bit like a "manié".
The distribution of these masses (law of inertia) gives the D-Contact the dynamic movement of a body in perpetual torsion trying to re-establish its position. The flat spectrum (achromatic color in all lighting conditions) of the broken rings and hooks avoids alerting the fish with supernatural flashes of light.
Swimming depth: 50cm and +.
