This magnet was specifically designed with magnet fishing in mind! You won’t have to worry which way the magnet is oriented under water since each side provides up to 500lbs of pulling force. The eyebolt screws into the side of the casing, rather than through the magnet to provide a larger surface area to catch targets. Includes M8 eyelet. This magnet is made with A3 steel plate and coated with Nickel-Copper-Nickel to be the strongest and most durable type of permanent magnet available.
