One common type is the Beat Frequency Oscillation (BFO) metal detector. How does it work, you may wonder? Well, think of it as a high-tech version of playing the guitar.

Just like when strumming a guitar, the BFO detector uses two coils – one to transmit a magnetic field and the other to receive any signals that bounce back. But what sets the BFO metal detector apart from the others? It’s all about the beat, my friend. You see, the BFO detector works by generating two different frequencies, one slightly higher and one slightly lower.

These frequencies “beat” against each other, creating a distinct oscillation. When the detector comes across a metal object, it disrupts the magnetic field, causing changes in the beat frequency. This change is then detected by the receiver coil, alerting the user to the presence of metal.

Now, you may be thinking, why choose a BFO metal detector over other types? Well, one advantage of the BFO detector is its simplicity. It is often considered the most basic and easy-to-use type of metal detector. Additionally, BFO detectors are known for their ability to detect different types of metal, including both ferrous and non-ferrous metals.

This makes them versatile for a wide range of applications, from treasure hunting to security screening. However, like everything in life, BFO metal detectors also have their limitations. One common drawback is their sensitivity to minerals and other environmental factors.

These factors can interfere with the magnetic field, leading to false readings or reduced detection depth. Additionally, BFO detectors are not as precise as some other types when it comes to determining the exact location and size of a metal object. Despite these limitations, many metal detector enthusiasts still find value in using BFO detectors for their simplicity and versatility.

Very Low Frequency (VLF)

“Types of Metal Detectors” When it comes to metal detectors, there are various types available on the market. One popular type is the Very Low Frequency (VLF) metal detector. This type of detector uses two coils – one for transmitting and one for receiving signals.

The transmitter coil sends out a magnetic field, while the receiver coil picks up the signals that are bounced back. VLF detectors are known for their versatility and are commonly used by hobbyists and treasure hunters. They can detect a wide range of metals and can be adjusted to different settings depending on the user’s preferences.

Additionally, VLF detectors are sensitive to small objects and can discriminate between different types of metals. This makes them ideal for locating coins, jewelry, and relics. Whether you’re exploring an old battlefield or searching for hidden treasures at the beach, a VLF metal detector can be a great tool to have in your arsenal.
