Want to know which is the best magnet for magnet fishing?
The quick answer is: it all depends.
It depends on your budget, how big and strong you want, what features you need. You may even need more than one magnet depending on your method and what you're trying to fish out. In the following sections, we cover the must-haves that we consider to be the minimum requirements for your magnet fishing magnet, and reveal our top magnet picks so you can choose wisely.
Must-Have Features For Your Magnet
Whichever magnet you choose, make sure it has all of these features at minimum.
Features:

• Neodymium Magnet (NdFeB)
• N42 Grade or higher
• Strong Coating (NiCuNi) with A3 Stainless Steel Cover
• Fasteners - Countersunk hole & eyebolt
• Pulling force at least 500lbs (226kg)

Neodymium Magnet (NdFeB)
Not all magnets are equal. The magnet to use for magnet fishing should be made out of an alloy of neodymium(Nd), iron(Fe), and boron(b) combined to form (NdFeB).
Neodymium magnets are the strongest type of permanent magnets (which means they create their own magnetic field with no need for an electric current) available on the commercial market.

N42 Grade Magnetic Field Strength
Look for magnets with at least a grade of N42.
Without getting scientific, the grade is the magnetic field strength; for example, if you have two neodymium magnets of equal size, the one with a higher N-grade has a stronger pulling force.

Strong Coating (NiCuNi) & A3 Stainless Steel Cover
You don't want your neodymium magnet to corrode and lose its strength. Look for a magnet that is coated in plated nickel(Ni), copper (Cu), and nickel (Ni). The NiCuNi coating provides protection from corrosion, and keeps the magnet from losing its magnetic force. The A3 grade stainless steel cover encases the entire magnet in one neat and durable package.

Fasteners - Countersunk hole & eyebolt
You want the ability to tie or attach anything to your magnet. A magnet with a countersunk hole is best so you can screw in an eyebolt, hook, or a regular bolt. With this, you can attach your magnet to any rig.

Pulling force of at least 500lbs (226kg) 
Generally, the bigger and stronger the magnet, the more expensive it gets. 
If you're just starting out, start with a 500lbs capable magnet. This will satisfy the majority of hauls without feeling like you're missing out. 500lbs is still a very strong magnet.
If you want to get any magnet fishing job done, then go with a 800lbs (362kg).
If you love the extreme, then go with a 1000lbs pull force (453kg).
If you're tactical, you can go with a double sided magnet. These types tend to have weaker power per side, but they are great if you're scanning the bottom and will increase the chances of you finding something. Once you've got something big and heavy (hopefully a safe full of gold bullion and diamonds, or a bag full of automatic assault rifles) then you can send in your 1000lbs magnet to help finish the job.
