Searching magnets are used for searching ferromagnetic items (steel, cast iron, nickel, cobalt, etc.) in natural water bodies (rivers, lakes, ponds), wells, mines, large reservoirs with water and other liquid (e.g., jerrycan with gasoline).
Searching magnets are powerful magnets which you can buy here.
Searching magnets are corrosion resistant due to three-layer coating Ni-Cu-Ni on magnets and zinc-plated steel case. That lets you use our searching magnet in water without a sign of rust.
We use permanent magnet alloy Nd-Fe-B, grade N45
