Metal detectors have become increasingly popular over the years for treasure hunters, gold prospectors, and hobbyists alike. However, with so many different types of metal detectors on the market, it can be challenging to determine which one is right for you. Two popular types of metal detectors are very low frequency (VLF) and pulse induction (PI) detectors. In this article, we will compare and contrast VLF and PI metal detectors to help you decide which one is the right fit for you.
VLF metal detectors are the most commonly used type of metal detector. They work by using two coils: a transmitter coil and a receiver coil. The transmitter coil sends out a magnetic field, which is then picked up by the receiver coil. If a metal object is present, it will disrupt the magnetic field, and the detector will emit a signal.
One of the main advantages of VLF metal detectors is their ability to discriminate between different types of metals. This means that you can set the detector to ignore certain types of metals, such as iron or aluminum, and only detect the metals you are interested in. VLF detectors are also excellent at detecting small objects and can be used in a variety of environments.
PI metal detectors are a more advanced type of metal detector and are typically used by professional treasure hunters and gold prospectors. They work by emitting short bursts of magnetic fields, which then create eddy currents in any nearby metal objects. These eddy currents create a secondary magnetic field, which is then picked up by the detector.
One of the main advantages of PI metal detectors is their ability to detect metal objects at greater depths than VLF detectors. They are also better at detecting large objects, such as buried treasure or gold nuggets. However, one disadvantage of PI metal detectors is their inability to discriminate between different types of metals. This means that they will detect all metals, regardless of their type.
Choosing between a VLF and PI metal detector ultimately comes down to your specific needs and preferences. If you are a beginner or hobbyist, a VLF detector may be the best choice for you. They are more affordable, easier to use, and can be used in a variety of environments. If you are a professional treasure hunter or gold prospector, a PI detector may be the better option. They are more expensive and more challenging to use, but they are better at detecting larger objects at greater depths.
In conclusion, both VLF and PI metal detectors have their advantages and disadvantages. It is essential to consider your needs and preferences before making a decision. Whether you are searching for buried treasure or just looking for a fun hobby, there is a metal detector out there for you.
