How to use radar principle to detect metals

1. continuous sine wave technology-this is the traditional technology adopted by most basic detectors. These detectors are usually called very low frequency detectors. When signal processing needs frequent adjustment, the way of sending and receiving signals does not change much. This is because this kind of continuous sine wave detector will produce electromagnetic field, which will act on the ground in the form of continuous wave.

2. Wide Spectrum Transmitting Technology (BBS)- Unlike VLF detectors that only use sine wave and square wave, this technology uses 17 frequencies to transmit at the same time. The further upgrade of this technology is the working mode of full spectrum emission (FBS). Full spectrum transmission has 28 frequencies working at the same time. This is the exclusive patented technology of Minelab. Its advantages are that it can minimize the noise of ground clutter and accurately distinguish different metal targets in a wide depth range. The appearance of this technology provides a wider application range for the main product used for treasure exploration in today's market-multi-spectral detector.

3.V/Flex technology-this is an extremely subtle technology. It uses digital components and mixed signal components to strengthen the standard single frequency technology, which is reliable and can improve the shielding effect of external interference. In addition, V/Flex technology allows the detector to work at different frequencies through the conversion coil.

4. Multi-period induction technology (MPS)-This is also a patented technology exclusively enjoyed by Minelab. It was first used in its SD series products, and now it is used in top GP series detectors and other mineral detector products. Minelab's unique multi-period induction technology (MPS) makes the detected object generate a changing magnetic field by emitting a pulse stream with long and short magnetic fields to the ground. In other words, compared with the traditional VLF detector, MPS technology can enable you to detect objects buried deeper. Moreover, MPS technology can improve the accuracy of ground balance, thus effectively reducing false positives and false signals.
