Key benefits - Accurate spot marking and depth measurement: precisely mark fishing spots and read water depth to help refine your carp fishing strategy and improve rig placement. - High visibility and stable performance: vibrant colors combined with a high-buoyancy design make the marker easy to see on the water and keep it steady for reliable monitoring. - Durable construction: made from ABS material with strong resistance to UV exposure and water flow, built to withstand regular use in outdoor fishing conditions. - Versatile for multiple environments: suitable for use in ponds, lakes and rivers, compatible with common carp fishing techniques. Features - Function: marks swim locations and measures water depth to support targeted baiting and rig setup. - Visibility: bright, easily seen colors for quick visual reference from the bank. - Buoyancy & stability: engineered to remain upright and stable even in light currents, aiding accurate readings. - Material: rugged ABS construction that resists UV degradation and wear from water flow. - Application focus: designed with carp fishing needs in mind and adaptable to typical freshwater environments. Practical use scenarios - Spot marking and return accuracy: drop the marker to identify a productive swim, measure depth, then return later or reposition rigs to the exact same location for consistent results. - Multi-rod sessions: mark multiple swims to maintain consistent bait presentation across rods and simplify monitoring while fishing. - Depth profiling in ponds, lakes or rivers: use the marker to check depth and current lines before setting rigs, helping you choose the correct tackle and bait placement. How it helps you fish better - Eliminates guesswork about depth and position so you can place rigs more precisely. - Improves consistency between casts and sessions by giving a reliable visual reference. - Reduces time spent adjusting tackle on the water by providing immediate, clear information about swim conditions. Materials and care - Constructed from durable ABS material with UV and water-flow resistance. Rinse after use in silty or salty conditions and store dry to maintain performance.
