Motion Metal Detectors
Motion metal detectors require no tuning and are silent until an object is found. When the search head is moving past a target the metal detector emits a sharp ‘beep’ to indicate its presence. The ‘beep’ occurs when the centre of the search head is directly over the target, to aid location.
Non-Motion Metal Detectors
Non-Motion machines are the most basic type of metal detector. When used, a faint sound is heard through the headphones or loudspeaker. When the search head is moved close to a metal object the sound rises in volume to indicate the presence of a target. This type of metal detector must be ‘tuned’ to obtain the maximum sensitivity to objects.
Found on metal detectors with multiple detection modes, the pinpoint button switches the metal detector into a basic Non-Motion mode to help accurately locate the target object.
Sturdy Three Piece Stem
This allows the metal detector to be easily broken down into 3 parts for transportation. The solid connection mechanism also eliminates wobble as the metal detector is swept across the ground.
The Target ID gives a reading for each target, represented by a number on the LCD between 0 and 95. A low reading corresponds with a poor quality target, possibly iron, whereas a high reading indicates a very conductive target, maybe silver or copper.
The lower part of the metal detector’s stem slides into the upper part and can be fastened in a number of positions, making the length of the detector adjustable. This allows comfortable use of the metal detector for detectorists of different heights.
Tuning controls are found on our non-motion metal detectors. They are used to adjust the faint threshold sound heard through the speaker or headphones when no object is close by. Ideally this should be set as low as possible, whilst still being audible, so the smallest variations caused by targets can be heard.
