This is a very strong magnet! The item was exactly as the seller described. Pull force measurements based upon the testing protocol used by the manufacturer look to be accurate from my uses however I did not replicate the seller's test protocol. The pull force of a magnet is directly tied to the material that is interacting with the magnetic flux lines of the magnet (more generically the magnetic field). Put very simply, the bigger a given type of magnet is, the more area its field can interact with vs another piece of material. If you attach this magnet to normal construction steels with a flat face that is larger than the surface area of the magnet like say an I-Beam or thicker construction steel strips (1/4 inch or above) you'll get quite a workout removing it. If you cover only the center of the magnet with said materials it will take work but much less. Please note most easily accessible stainless steels aren't great for magnetic force tests. Put this next to your average stainless steel bowl or drinking cup and it will barely attract. However if you have high quality stainless steel cookware designed for an induction stove the base will stick to this magnet like glue due to an embedded induction plate, usually of iron. Science does have its uses sometimes :-)

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. Using the best technology, we make sure our customers always get the correct magnet for their application.
Not satisfied with this, we figured that we should show up at the lake with some bigger, stronger magnets that would be ridiculously strong.  For the monster magnet picker-upper, we bolted three MMS-B-Z0 magnets across a length of aluminum extrusion, and tied that to our rope.  This setup is a lot more powerful, so we did worry about it getting attached to something that would exceed our ability to pull up with a rope.
WARNING Powerful magnets should be handled with extreme care. Severe pinching and other serious injury may occur. Keep this product away from bank cards, medical devices including pacemakers, magnetic media, electronic devices such as computers, monitors, laptops, televisions, mobile phones and tablets. Magnets might affect water, gas, electric, and other metering equipment. Keep away from children and store this magnet in a safe place when not in use. Please use safely and responsibly.
We highly recommend using a good nylon paracord because of its strength, durability, elasticity, high abrasion resistance, and its ability to hold a knot very well; all these are important given the conditions that you may be fishing in where the water could be murky and the magnet becomes snagged on to something which would take some strong yanking of the rope to un-snag it. Its elasticity gives it slack, and since the paracord rope is light and thin, the pulling feedback you get when feeling the rope is a lot more sensitive; you will know when the magnet has caught something. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon and the Amazon logo are trademarks of, Inc, or its affiliates.

Magnet fishing is suited for people who are curious, enjoy the outdoors, and who are patient. You can be a type of explorer, adventurer, and a big game hunter as your main interest, but the simplicity of just dropping a magnet and reeling it in after you sense the ‘magnetic clunk’ creates the excitement and anticipation of what will be brought to the surface. This excitement will never get old as you explore new places to fish, or quickly stop to drop your magnet when you stumble upon an interesting place. You can spend as little or as much time as you want on this hobby. Remember, you’re always one cast away from finding your next metal treasure.
Great size and seems to have a pretty good pulling strength. My first trip out to the lake using it I managed to pick up some interesting things. The eyebolt definitely needs to have some thread locker applied and I needed to add a DIY soda bottle shroud, but other than that this magnet worked perfectly. I’ll probabky order a second one for my daughter.
Super strong magnet for the money. Being a back yard mechanic I’ve used it multiple times to find to find bolts and parts I dropped in the grass from my boat and cars. It’s already paid for itself twice in the time and money it’s saved me getting new parts. The kids had it stuck on the fridge and climbed up the side, the only way I got it off was by sliding it to the side. Don’t let your 5 year old play with it!
Due to the recent influx of new magnet fishers, I thought I'd write a general tips and tricks guide to get the new people up to speed. I've been doing this for about 5 months now, with great success in the Minneapolis area. This guide will be broken up into choosing a setup, finding a spot, fishing methods, and conclusion/maintenance. (All units will be in freedom units, so I apologize in advance to our European friends)
This neodymium round base magnet is made of a super strong neodymium magnet encased inside a chrome plated steel cup. The neodymium fishing magnet is bonded inside of the cup with adhesives. This design forms a magnetic circuit which triples the holding force to 405 lbs! At the same time, the steel cup also protects the fishing magnet from being damaged when frequently used. The eyebolt is provided for easy use but you can replace it with your own designs.
