Metal Detecting History and Development Pulse Induction

Metal Detecting History and Development Pulse Induction

Traditional Metal Detectors have been around for several decades. They work by passing a magnetic field through a coil, and measuring the field that any objects create as they interact with the created magnetic field.

If an object is metal, it will create its own magnetic field. This variation will be able to be measured, and that is the basic function of how traditional magnetic detectors work.

Pulse Induction metal detectors function in that they detect and can work in areas where there are metallic sands or other reasons that traditional radio frequency magnetic fields cannot.

Pulse Induction scanning techniques work as a high-powered voltage pulse signal is sent into the ground. The signal decays at a set rate, and the time that it takes to decay can be measured and any variations can be detected.

Using new coil arrangements and designs and introduction of “junk eliminator circuits” new and improved Pulse Induction Metal detectors are able to exercise a greater detection ability and to find and locate metal to greater depth than ever before.

Pulse induction metal detectors are now used in the construction industry, and large objects that can be detected up to 10 feet deep are possible using a large 12 or 15 inch coil.

With the help of computerized circuits it is now possible to set limits on discrimination, sensitivity, volume and notch filter stetting, and to even program the pulse metal detector for future use and to save the settings in memory.

Compared to even just 10 years ago Pulse Induction metal detectors can now function with less battery power, discriminate better, find objects deeper and perform 1000 percent better than their older brethren.

The ability of metal detection has come into its own with the modern Pulse Induction detectors.
