Types of Metal Detector Technology

When it comes to metal detectors, there are several types of technology that can be used. One of the most common types is known as VLF, or very low frequency, technology. This type of detector uses two coil systems to send and receive electromagnetic signals.

Another type is PI, or pulse induction, technology. PI detectors work by sending short bursts of current through a coil, which creates a magnetic field. When a metal object is detected, the magnetic field is disturbed, and a signal is sent to the control box.

A third type is known as BFO, or beat frequency oscillator, technology. BFO detectors work by using two oscillators, one for the search coil and one for the reference oscillator. When a metal object is detected, the frequency of the search coil oscillator changes, and a beat frequency is created.

These different types of technology all have their own advantages and disadvantages, so it’s important to consider what type of metal detecting you will be doing and what features are most important to you.

1. Beat Frequency Oscillation (BFO)

BFO, or Beat Frequency Oscillation, is one of the types of metal detector technology available in the market today. It is often favored by beginners due to its simplicity and affordability. The BFO metal detector works by transmitting two different frequencies and then analyzing the beat frequency that results from the interaction between these two frequencies.

When the detector comes into contact with a metal object, it disrupts the frequencies, causing a change in the beat frequency. This change is then detected by the device, alerting the user to the presence of metal nearby. While BFO technology is effective at detecting larger metal objects, it can sometimes struggle with smaller or deeply buried items.

However, it is still a popular choice for hobbyists and beginners who are just starting their metal detecting journey.

2. Very Low Frequency (VLF)

VLF stands for Very Low Frequency and is one of the common types of metal detector technology. This technology works by emitting a low-frequency magnetic field into the ground. When the magnetic field encounters a metal object, it creates a magnetic field of its own, which the metal detector then detects.

VLF metal detectors are known for their ability to discriminate between different types of metals, allowing users to differentiate between valuable items like gold and silver and less valuable items like nails or bottle caps. This makes them popular for treasure hunting and relic hunting, as they can help users focus on finding the good stuff. Additionally, VLF metal detectors are generally lightweight and easy to use, making them a great option for beginners or casual hobbyists.

So if you’re looking to discover hidden treasures or simply have fun exploring, a VLF metal detector might be just what you need!

3. Pulse Induction (PI)

The Pulse Induction (PI) is one of the types of metal detector technology. It is known for its ability to detect metal in highly mineralized soil and in saltwater environments. Unlike the Very Low Frequency (VLF) technology, which uses two coils to transmit and receive signals, the PI technology uses a single coil to do both tasks.

This makes it more sensitive to small metal targets and allows it to penetrate deeper into the ground. The PI technology works by sending short bursts of magnetic pulses into the ground. When these pulses come into contact with metal objects, they create an electric current that is then detected by the metal detector.

This makes the PI technology ideal for searching for deeply buried objects or for use in areas with a high level of mineralization.

Comparison of Metal Detector Technologies

When it comes to metal detectors, there are several different types of technology that can be used. One of the most common types is known as very low frequency (VLF) technology. This type of metal detector uses two coils – a transmitter coil and a receiver coil – to create a magnetic field.

When this magnetic field comes into contact with metal, it disrupts the electromagnetic field and alerts the user to the presence of metal. Another type of technology is called pulse induction (PI). This type of metal detector sends out short bursts of electricity to create a magnetic field.

When this magnetic field comes into contact with metal, it creates a secondary magnetic field, which the detector can detect and alert the user to. Both VLF and PI technology have their advantages and disadvantages, so it’s important to choose the type that best fits your needs and preferences.

1. Sensitivity to Different Metals

sensitivity to different metals, metal detector technologies Blog Section: When it comes to metal detectors, not all technologies are created equal. One of the key factors that sets different metal detectors apart is their sensitivity to different metals. Different technologies are better suited for detecting specific types of metals, and understanding this can greatly improve your metal detecting experience.

One technology commonly used in metal detectors is Very Low-Frequency (VLF) technology. VLF detectors are highly sensitive to low-conductivity metals such as gold and silver. This makes them a popular choice for treasure hunters who are searching for these valuable metals.

VLF detectors use two coils—an outer search coil that detects metal objects and an inner coil that helps the detector discriminate between different types of metals. This discrimination capability allows users to identify specific types of metals and ignore unwanted targets. On the other hand, Pulse Induction (PI) technology is known for its ability to detect highly conductive metals such as iron and steel.

PI detectors emit short bursts of high-frequency waves into the ground, which creates a magnetic field. When the waves hit a metal object, the magnetic field is disrupted, causing the detector to sound an alert. This technology is particularly effective for finding deeply buried or large metal objects, making it a popular choice for beach and water hunting.

While both VLF and PI detectors have their advantages, it’s essential to consider the types of metals you are most likely to encounter during your metal detecting adventures. Are you searching for gold or silver? Or are you more interested in finding iron or steel artifacts? By understanding the sensitivity of different metal detector technologies, you can choose the one that best suits your specific needs. Remember, it’s also crucial to practice with your detector and become familiar with its discrimination capabilities.

This will help you differentiate between different types of metals and maximize your chances of finding that elusive treasure. In conclusion, metal detector technologies differ in their sensitivity to different metals. VLF detectors are great for detecting low-conductivity metals like gold and silver, while PI detectors excel at finding highly conductive metals such as iron and steel.

2. Depth of Detection

These technologies vary in their ability to detect metals at different depths. One commonly used technology is known as VLF (Very Low Frequency).

VLF detectors operate by sending out a continuous waveform and measuring the changes in that waveform when it encounters metal objects. This technology is known for its ability to detect metal objects at shallow depths. Another technology is Pulse Induction (PI).

Unlike VLF detectors, PI detectors use a series of short bursts of magnetic pulses to detect metal objects. This technology is particularly effective at detecting metals at greater depths. Ground Penetrating Radar (GPR) is another technology that can be used for metal detection.

GPR works by emitting high-frequency radio waves into the ground and measuring the reflections that bounce back. This technology is known for its ability to detect metals at deeper depths, but it is also more expensive and complex to use. Overall, the choice of metal detector technology depends on the specific needs and requirements of the user.
