Metal Detector - Multifrequency

They use the ability to work with several frequencies simultaneously

Multi-frequency metal detectors are a type of detector that use the ability to operate at several frequencies simultaneously or optionally switch between different frequencies according to the user's needs. This technology is key to increasing the efficiency and adaptability of the detector in different conditions and for different types of metal targets.

How multi-frequency metal detectors work:

  1. Current frequency analysis:

    • Multi-frequency metal detectors generate signals at several frequencies simultaneously. Each frequency has different characteristics that are suitable for detecting different sizes and types of metals. For example, higher frequencies are better for detecting small targets and low frequencies for deeper and larger targets.
  2. Data Processing:

    • Signals from different frequencies are processed either in parallel or sequentially to obtain the clearest and most detailed picture possible of the nature and depth of targets underground. The resulting information from this analysis allows more accurate identification of metallic objects and discrimination between desirable targets and metallic waste.
  3. Advantages of multi-frequency detectors:

    • The ability to operate at different frequencies simultaneously increases the probability of detecting small, medium and large targets at different depths. They also improve the detector's ability to operate in a variety of soil conditions, including mineralized soils or under water.

Minelab's pioneering role in multi-frequency technologies:

Minelab Is a recognized pioneer in multi-frequency detection technologies. Among the most important technologies developed by the company are:

  • Multi-IQ:

    • Multi-IQ is a technology that uses multiple frequencies simultaneously for enhanced sensitivity and performance in a variety of detection conditions. This technology is effective in distinguishing between different types of metals and provides exceptional depth and speed of detection.
  • Full Band Spectrum (FBS):

    • FBS technology uses a wide range of frequencies to scan the ground, allowing the detector to detect and identify metals at various depths with high accuracy. It is ideal for searching in a variety of soil types.

Multi-frequency metal detectors, such as those from Minelab, provide prospectors with advanced options and benefits when searching for treasures in a variety ofenvironments and conditions, making these detectors very popular with professionals and amateurs alike.
