The Preston Innovations Feature Finder Leads are purpose-built for anglers seeking to accurately map the contours of a lakebed. These leads enable precise identification of specific fishing areas, helping to distinguish between different bottom types and locate clear spots, while also assisting in avoiding heavily weeded sections. Their aerodynamic design supports accurate and long-distance casting, essential for exploring wider areas. Key features of the Preston Feature Finder Leads include: - Small nodules for identifying different lake beds - Aerodynamic design for enhanced casting - Large eye swivel These leads are available in two common weights, 30g and 45g. For optimal performance in detecting bottom features, it is recommended to use them in conjunction with a braided mainline. Some packs contain two leads.
