How To Choose The Best Metal Detector Under $100?
First, you have to understand how a metal detector works. Every metal detector features a search coil, which transmits an electromagnetic field into the ground. If there is a metal object within the field, it will retransmit the field with its own frequency. Thanks to this, the metal detector can differentiate the type of metal it has found and allows you to ignore unwanted metal.
A high-frequency metal detector is ideal for small targets, while a low-frequency metal detector is ideal for large targets. Very low-frequency ones, which I review above, are suitable to find coins and jewelry.
The accuracy is the first priority when choosing a metal detector. Then, you’ll have to notice the detection depth. Other functions you may like to have are sensitivity adjustment, discrimination mode, notch mode, and a large informative LCD display.

FAQs
Which circuitry type is better?
Metal detectors use inductive sensors to detect the change in the electromagnetic field, which is an indication of the metal underground. There are some inductive sensor types. A standard inductive proximity sensor detects non-magnetic metals well (aluminum, copper, and brass) but is very bad at detects magnetic metals (steel). There are also ferrous only sensors (magnetic metals only) and non-ferrous only sensors (non-magnetic metals only). So unless you are aiming at detecting only a type of metals, I recommend having a metal detector that features a standard inductive proximity sensor.
Where can you legally metal detect?
You don't have to worry much about permission to metal detecting. You can legally metal detect in local parks, state parks, national forests, beaches, or of course, your backyards.
How much does a really good metal detector cost?
A serious metal detector for adventurers may cost above $1,000. A decent metal detector costs about several hundred dollars. However, you don’t need to spend that much if you are just looking for a toy for your kids - a metal detector under $100 would be enough.
How can you tell if metal is underground?
There is no trick. You need to search inch-by-inch with a metal detector to find metal underground. That’s the fun of the game, right? You can also go online searching for places that are likely to have treasure underground.
Can metal detectors go through concrete?
Concrete may contain rebar inside it, which is a problem when you metal detect through it. Otherwise, it is perfectly okay to metal detect through concrete.
Can a normal metal detector find gold?
All metal detectors find gold if it is within the detection range and not be blocked by other metal.
Conclusion
Treasure hunting is a good game for the family bond. I hope that you and your family will have good times with this game.
