Using a marker float in carp fishing adds a layer of precision and strategy to the angler's approach. A marker float is a buoyant device that helps anglers map the underwater topography and identify key features like drop-offs, gravel bars, or weedy areas. As the marker float is cast out and allowed to settle, it provides a visual reference point for the angler, allowing them to gauge the depth and structure of the lake or riverbed. This information is crucial for selecting optimal fishing spots
