Efficient Water Depth Tracker Designed for carp fishing, this marker float provides precise depth tracking and marks key spots, helping you optimize where to cast and how to present baits. Stable Visibility on the Water Features stable floating with buoyancy to stay easily observable. Bright, visible colors ensure clear visibility in various water conditions. Durable and Dependable Built with sturdy ABS construction. UV resistant and resistant to water flow, delivering a wearresistant solution for reliable onwater use. Versatile for Multiple Environments Suitable for carp fishing in ponds, lakes, and rivers. Widely applicable design works across different water conditions and angling preferences. Key attributes Function: water depth tracking and spot marking for carp fishing Material: ABS construction, UV resistant Performance: buoyancy for strong visibility, stable floatation, wearresistant and durable on water Compatibility: ideal for ponds, lakes, and rivers; suitable for various water conditions Use scenarios Scenario 1: Calm pond with weed lines. Use the marker to identify and mark depth near structure to guide rigs and bait presentation. Scenario 2: Open lake with light currents. Deploy markers at varying depths to map productive zones and adjust depth and rig placement. Scenario 3: River environment with mild flow. Place markers to track depth changes along bends and eddies for effective spot fishing.
