All You Need to Know About Metal Detectors


Metal detectors are electronic devices that detect the presence of metals nearby. They are useful for discovering metal objects that are buried underground or metal inclusions which are hidden within objects. Basically, a metal detector is made of a handheld unit which has a sensor probe that can be swept over the field or other objects.

If you opt to buy such gadgets in the future, it is essential that you research first before considering any seller. It is only after good research that you will be able to secure a genuine purveyor of detectors that will guarantee you with affordable quotes, very satisfactory services and genuine products.

History of Metal Detectors

The first industrial detector was introduced in the 1960s and was extensively used for mineral prospecting matters and other industrial applications. Metal detectors in those years were used to detect land mines, detection of weapons like guns and knives, treasure hunting and geophysical prospecting.

Types of Metal Detectors

Choosing the right kind based on your goals and budget is often the key to picking a product that suits your needs perfectly and one that will not disappoint you later. Here is an overview of the three types of metal detectors that are recently being sold in the market;

1. Beat Frequency Oscillation i.e. BFO Detectors

Beat frequency oscillation is the simplest of all detectors and therefore cheapest in terms of price. The gadget is considered ideal to be utilized in treasure hunting by people who are relatively new in the sport. When treasure hunting, the beat frequency oscillation uses two separate wire coils to detect metal objects. Oscillators create signals that are constant with set frequencies. These signals then get omitted from one of the BFO’s coils.

Basically, if one of the coils omits signals the primary responsibility of the other will be to effectively detect interference of frequency which discovered objects can cause. Once the detector discovers any object, it will notify you by a tone signaling or by changes in audio sounds.

2. Pulse Induction Detector

Pulse induction (Pl) detectors are mainly used to search deep under surfaces for treasures. These types of detectors are also popularly used at checkpoints which need security for weapon or metal detection. In case there is a metal under the surface, this kind of metal detector will end up reflecting signals which its user(s) can listen for. With pulse induction detectors, only one of the coils has the sole purpose of signaling a magnetic field in the ground or surface. Pl also switches modes to assist users figure out reflected signals that are found.

3. Very Low Frequency Metal Detectors

Very low frequency (VLF) detectors are the most commonly used of all detectors because of the high- end technology that has been used to make it. The detector has two round coils of wire, a receiver and a transmitter.

The purpose of a transmitter is to emit low frequency magnetic field onto the ground or surface meant for treasure hunting. The receiver on the other hand is solely used for magnetic reflection purpose.

This type of metal detector also includes a tuner, also referred as an electric circuit that filters signals to the detector’s receiver.
