TERMINOLOGY
The following terms are the common terminologies among the metal detector.
Motion Mode
Continuously moving the search coil is one of the circuit operation modes within the metal detector's built-in
detection technologies. You have to move the search coil during detecting -- preferably in a overlapping 'painting'
pattern. Generally speaking, motion detection mode can reduce the effect of misleading / unwanted soil mineralization
detection, and will have a better discrimination ability for more sought after findings.
Non-Motion Mode
This is your other metal detection option included within the detector's circuitry operation modes. When searching,
you need not move the search coil continuously, as long as your hover to locate and zero-in on your finding. When the
metal detector locates the object in non-motion mode, the detector cannot discriminate the metal categories -- in other
words, the discrimination levels do not function as in motion mode.
Elimination
To eliminate a particular metal while detecting is based on the user's preference. While searching the operator can
distinguish the specified metal, based on the metal detector's reaction to the search coil's response (a different sound in
tone and/or lighting indication can be differentiated). Please note, not all metal detectors feature a diverse and/or
wide array of detection elimination options and differentiation.
Discrimination
The detector creates sounds in different tones and/or gives different display and/or light indications to different metal
types. Discrimination also has the somewhat similar ability to also eliminate or 'zero-in' on the location/detection of
select metals. This is referred to as “discriminating”. Discrimination is one of the most important features of the metal
detector (a different sound in tone and/or lighting indication can be differentiated). Please note, not all metal detectors
feature a diverse and/or wide array of detection elimination options and differentiation..
Metals
The common metals are alloys, such as copper, due to the different character composition of different metals, they are
most generally divided and grouped by categories like: red copper, brass, bronze, etc. However, the same metals can
provide different detection / metal detector indication -- and vice versa, different metals can provide similar detection /
metal detector indication. With a same metal, due to the different composition, shape and differences in the degree of
oxidation, resulting in electrical conductivity or magnetic permeability are not the same, as in the metal detector, there
are more often different responses.
