Mommotti 140/180 SF is a saltwater jerk that in a very short time has gained a great consensus among European fishermen. It is designed to ensure long cast in the most difficult weather and sea conditions and continuous flashes during jerk. A basic lures for the Mediterranean angler. We have deliberately tried a relationship weight-volume that would guarantee us long cast and at the same time a refined lightness in swimming, both in linear retrieve and cast, which makes them very stable even in the presence of currents and towards apathetic predators. The choice of the inner armor forced us to a particular design effort in the distribution of internal tungsten weights with a constant attention to the perfection of the action of swimming. Suitable for all predators such as seabass, bluefish, barracuda, leerfish, dolphin fish, amberjack, seabream, and tuna species. The research led to create a slight ventral bend giving the lure extra instability in swimming and which proved to be particularly enticed to predators. The slight curvature in its ventral part creates a unique and more disordered swimming extremely capturing in particular during jerking action.
