Thanks to its irregular surface, it is perfect when the lead needs to stay firmly on the bottom. The Big Grippa model is therefore the ideal option for fishing in rivers, lowering rigs at a distance with boats when backwaters could cause problems, and for casting on sloping surfaces, such as the shore of a small island or a gravel bank, because, unlike leads of other shapes, it will definitely stay in position. Well known among carp anglers both in the United Kingdom and the rest of Europe, the Big Grippa model is widely used for fishing barbel and chub.
