As explained before, target ID is a 2 digit number defining the target, produced by the metal
detector while the search coil goes over a target The number is shown on the display as TARGET ID.
In some cases, the device may produce multiple IDs for the same target. This may result from a
couple of factors. Target orientation, depth, purity of the metal, corrosion, mineralization level of
the soil etc. Direction of the search coil swing may even cause the device to generate multiple
IDs.
In some cases the device may fail to provide any ID. The device needs to receive a strong and a
clear signal from the target in order to provide an ID. Therefore, it may not be able to provide an
ID for targets which are too deep or too small even if the device detects them.
Keep in mind that target IDs are “probable”, in other words, estimated values and it would not be
possible to know the properties of a buried object exactly until it is dug out.
IDs of non-ferrous metals such as copper, silver, aluminum and lead are high. Target ID range of
gold is wide and may fall within the same range of metal wastes such as iron, foil, screw caps, and
pull tabs. Therefore, if you are looking for gold targets, digging out some trash metals is
expectable.
Some possible Target IDs and their ranges are indicated in the table below.
