FAQ (Frequently Asked Questions)
What is Target ID?
Target ID is the metal detector’s way of displaying the identity of a target in the form of a number. This complements the discrimination control by giving you the information the metal detector uses when it makes the decision whether or not an object should be detected. This allows you to determine accurately an object’s conductivity, giving a strong clue as to its identity.
On metal detectors with a discrimination control it was only possible to determine whether an object was more or less conductive than a chosen value. For example, if the discrimination control was set half way and an object was found, it would not be possible to tell whether it was a pound coin or a silver shilling.
Target ID gives you this information, as the shilling would be more conductive and so a higher number would be displayed.
This information is presented in two ways. Firstly a bar is shown when an object is detected. If the object is of low quality, iron or steel, only one or two segments will be shown. For a very good object, for example a silver shilling, the bar will fill up completely. This provides a very quick way of identifying the object.
For more accurate identification, the Target ID number shows the point on the discrimination control at which each target would be rejected. As an example, a modern 5 pence piece would only just be rejected when the discrimination control is set somewhere between 50 and 60. When detected, the bar will fill up half way and the number '55' is shown.
