Two are the main factors that characterize the model: the type of joint and the fan-shaped lip. The decision to reduce the joint part only in the third rear of the lure has a twofold purpose: to build a much more natural swim and not like a snake, typical of “swim baits” and minimize friction with the air during the cast phase, thus surpassing the characteristic defect of the jointed which consists in having a usually long cast. The fan-shaped lip, which characterizes the Buginu series probably gives its best in the series “Bìu” (in Sardinian language means “alive”) because it guarantees a natural and extremely tight movement with a very reduced roll. The lip in this model is intentionally undersized to accentuate further the naturalness of swimming and to allow broader customization. Although this type of lure is mainly studied for seabass, the Buginu 105 Bìu can be used with great success in fresh water. The lip shape is a “Patent design”.
