Diymag Part#: HLCT60MM - DIYMAG Super Strong Neodymium Fishing Magnets, 330 LBS(150 KG) Pulling Force Rare Earth Magnet with Countersunk Hole Eyebolt Diameter 2.36 INCH(60mm) for Retrieving in River and Magnetic Fishing

DIYMAG Round Neodymium Magnet with Diameter 2.36inch and Thickness of 0.59inch
We never compromise on quality and all our products are performance tested using a computer controlled tensile and compression machine. The system accurately measures the weight a magnet can hold when pulled vertically and the amount of pull a magnet can exert when there is a gap or non-magnetic material between the magnet and the material it is applied to attract.

China produces approx. 97% of the world's neodymium magnet supply. We evaluated about a dozen different Chinese producers, reviewed their price/performance ratios and we think this Round Neodymium Magnet is the best one.

Ensure the use of Security and Get a lots of fun
This fishing magnet is made up of a super strong neodymium magnet inside of a chrome plated steel cup that concentrates the magnetic force to give this an almost unrivalled 330 lbs of holding power

The heavy duty construction of this magnet features a female threaded steel cup and a threaded eye bolt that attaches directly to the cup instead of through the magnet.so it can Ensure the use of Security. Lots of Fun for River and Lake Fishing as Vacation and Family Activities. Great for Spending Time with Family Exploring What Can be Found in Rivers, Lakes or Anywhere Else.
