By far, gold detectors are the most popular tool among amateur prospectors and treasure hunters. Gold detectors are metal detectors – specifically constructed and calibrated for gold hunting. To explain how these tools excel at finding gold, it helps to understand the science behind basic metal detectors. Metal detectors work by transmitting an electromagnetic field into the ground, and then analyzing the return signal. The electromagnetic field transmitted by the detector induces loops of electrical current, called eddy currents, within conductive materials (i.e. metals). Eddy currents generate their electromagnetic field, which the detector receives and analyzes.
Gold detectors take this process a step further by measuring inductance and conductivity. Inductance refers to the amount of eddy currents produced in the target. Conductivity refers to how easily those currents flow. By measuring the size of the eddy currents and how fast they are travelling, a
gold detector can calculate the “time constant” of a target. Time constants can vary considerably between targets. For example, bits of aluminium foil have very short time constants, gold coins and rings have longer time constants, and scraps of steel, iron, and other ferrous metals have even longer time constants.
Gold detectors can be calibrated to specifically search for targets that fall within that “middle” range. Unfortunately, it’s not a foolproof method. The size, shape, and distance of a target (along with other environmental variables) affect the accuracy of the detector’s time constant calculation. To compensate, the gold detector can be re-calibrated on the fly to search for a broader or narrower range of time constants. High Plains Prospectors has put together bundles of gold-detecting equipment from top manufacturers. These carefully curated bundles include everything you need to get out into the field to search for gold and other treasures. Our bundles include pinpointers, carry bags, digging tools, sand scoops, jewellery loops, find bags, headphones and more. If you don’t see a bundle that suits your needs, feel free to contact one of our expert gold detection staffers who can help put together a custom bundle just for you.
Metal detectors can be classified according to several classifications, and the most popular classification is according to the search system or search technology in the device.
