Types of Metal Detectors

Understanding Metal Detectors If you’ve ever gone to the beach, you’ve probably seen people walking along the shoreline with metal detectors. But did you know that metal detectors come in all shapes and sizes, each designed for a specific purpose? Understanding the different types of metal detectors can help you find the one that is right for you. One of the most common types of metal detectors is the “beat frequency oscillator” (BFO) detector.

This type of detector is great for beginners because it’s easy to use and relatively inexpensive. BFO detectors work by transmitting a constant radio signal and then picking up any disturbances in that signal caused by metal objects. They are great for finding large metal objects like coins and jewelry.

Another popular type is the “very low frequency” (VLF) detector. VLF detectors are more advanced than BFO detectors and are capable of detecting smaller metal objects. They work by transmitting a low-frequency magnetic field into the ground and then measuring the magnetic field that is reflected back.

VLF detectors are great for finding smaller items like gold nuggets or relics. For more specialized purposes, there are also “pulse induction” (PI) detectors. These detectors use a single coil to transmit a short burst of current into the ground.

They then measure the time it takes for the magnetic field to decay and return to its base level. PI detectors are great for finding deep targets and can even work in highly mineralized soils. Finally, there are “multi-frequency” detectors that combine the best features of both VLF and PI detectors.

These detectors are able to transmit and receive multiple frequencies simultaneously, allowing them to detect a wide range of targets. Multi-frequency detectors are great for all-purpose detecting and can be used in a variety of environments. In conclusion, understanding the different types of metal detectors can help you choose the right one for your needs.

Common Reasons for False Alarms
