Magnetic Depth Finder for Fishing
- Strong magnetic grip prevents accidental detachment
- Quickly and accurately finds bottom depth
- Waterproof and rust-resistant material

Working Principle - Fast Depth Finding
- Detects water depth to accurately find the bottom with the hook
- Synchronously adjusts float markings
- Balances line rig setup
- Acts as a sinker weight to pull the hook to the bottom

Product Usage Method
- 1. Overweight Lead: The lead weight is heavier than the float's buoyancy, pulling the float underwater.
- 2. Trim Lead: Reduce lead weight until the float lifts the lead into a suspended position with 4 mesh markings exposed above water.
- 3. Attach Depth Finder: Add weight to pull the hook to the bottom while lead remains suspended; adjust float until 4 mesh markings are exposed.
- 4. Remove Depth Finder: Take off the depth finder tool to finish setting the depth.
