Made up of N42 neodymium magnet embedded a steel shell, it concentrates the magnetic field on the bottom and top of magnet which increase the magnetic force by 2.5-4 times compared to the naked magnet .
The steel cup will prevent the naked magnet from crackings and chippings.
Designed for heavy duty and underwater use, it can recover lost equipment, tools, ancient ferrous object and others in deep water, wells, holes, also great for lifting, hanging applications.
1. Material: Neodymium Magnet N42+A3 Steel+Black Resin
2. Size: D74″*28″mm(Diameter*Thickness)
3. Vertical Pull-force 300KG Horizontal Pull-force: 66KG for each side(Two Side Attracting Surfaces) On Base of 30mm Thickness Steel Plate
4. Max Working Temperature:80℃
5. Package Included: One fishing magnet+ one M10 eyebolt.
1.The 300KG is the vertical magnetic pull-force which makes the magnet pull way from the 30mm thickness steel plate of a tensile tester under ideal condition. It does not mean the actual weight which the fishing magnet can lift
The actual pull force will vary mainly depending on the following variables:
A: Steel thickness (The thicker the steel is, the stronger the pull force)
B: Attracting position (The farther beyond the center of gravity of the attracted object, the lower the pull force).
C: Pulling direction (The smaller the angle taking 90° as a standard, the stronger the pull force), the Pull force in horizontal direction is only about one third of that in vertical direction)
2 Magnet just only attract iron, ferrous metal and nickel, do not attract gold, silver, copper, aluminum and their alloy and stainless steel
Much Stronger: Combined vertical pull force 600KG magnetic surface (Two attracting surface, 300KG each side) on base of 30mm thickness steel plate under ideal condition due to the real high grade and bigger size naked Neodymium Magnet N42
More Efficient:Double-sided magnetic attracting structure increasing two times attracting surfaces and have a much stronger magnetic field. Without considering the pulling direction, It can attract ferrous metals in great distance.
Multi-USE:Unique two threaded holes design. Screwing eyebolt into the center hole is suitable for lifting vertically ferrous objects from well, bridge, boat and others; the side hole is great for trawling the bottom of the river, reservoirs, lake for iron metal or treasures.
Good Corrosion-resistance: Ni+Cu+Ni Tripler Layer good corrosion-resistance coating, used both in fresh water and in marine. Steel shell can avoid the naked magnet from scratching and chipping. Loss of magnetic properties no more than 2% within 10 years
100% NO Risk: All production processes carry out strictly per IS09001:2008 quality system. All fishing magnets undergo extensive testing for tensile strength, they can be returned within 120days and refund your money in all If do not meet your expectation.
