I think you want to get into the magnet fishing hobby. But you are still confused. You don’t know what is the difference between single and double-sided magnets, and which one should you chose.
I’ll explain the pros and cons of each one of them. Then I’ll help you decide which one you should pick.
But, there are other things to consider in order to pick the best fishing magnet. You can find them here.
OK, now let’s go back to the comparison…
Single-sided magnets have a tendency to roll on their sides or on their backs when you drag it along the bottom of the lake. This is due to their shape and to the eyebolt location.
The pulling force in concentrated on the bottom and it is weaker on the sides. Second, the contact surface will be limited when the magnet rolls over.
It still can attract metal objects when it is in this position. But, it won’t be as strong as when it is facing downwards, reducing thus the number of targets that you can hunt.
There is also a second problem with single-sided magnets. When you pull them along a river, they snag on rocks easily.
However, this problem isn’t a big deal. In this guide, I’ll show you how to solve it in no time.
The double-sided magnet doesn’t have this problem. It will always be on one of its flat sides, which is the strongest part.
Second, is snags on rocks less often. It rolls over and gets out of the way. And there is less surface facing obstacles.
Now here comes the part where single-sided magnets perform better than double-sided ones…
Although, the double-sided ones can be used from high spots. It won’t be as good as the single-sided magnets.
In this case, the first one will be facing the water with its edge (which is the weaker side). The second one will be facing the water with its flat surface.
I think, that you now see that none is better than the other. Every one of them has a role. It is like a knife and a fork.
You can use both of them. But if you are just starting out. I say you go with the single-sided version.
Single-sided is better if you are hunting from a high spot (a bridge, a dock…). Double-sided is better if you are on the same level as the water.
You can also have a 2 in 1 magnet.
Countersink hole (flat contact surface)
The distance between the magnet’s surface and the metal should be as small as possible. You don’t want any obstacles between the two.
Generally, the eyebolts of single-sided magnets are attached with a screw. The head of the latter is at the bottom of the magnet.
Pick the ones that have a countersink hole (or with a flat bottom surface).
This way, the screw that holds the eyebolt in place won’t get on the way. The surface will be smooth and you’ll get the maximum pulling force. The head of the screw will sit flush with the surface.
For double-sided ones, you don’t have to care about this point since the eyebolt is on the side. So there is no direct contact between the screw and the metal pieces.
