Designed for heavy-duty lifting and underwater use, these Retrieving Magnets means business! A Retrieving Magnet is a useful accessory to have around your fly tying work station, boat, or workshop. Its ability to recover hooks, nails, beads, and other ferrous material is second to none. Plus, a threaded hole with screw in ring (rope not included) allows the Retrieving Magnet to be lowered into the water and other hard-to-reach places. Heavy-duty magnet comes in handy when you've lost important tools, heavy metal objects--even small motors--at the bottom of your favorite lake or stream.
