Features

The C.Scope M-Scan magnetic locator is a flux-gate 
magnetometer. It responds when it detects ferromagnetic 
material (material that is able to be magnetised, such as iron) 
by increasing the audio frequency to a higher pitch as the object
is approached and passed. It is not affected by other objects
without a magnetic property. Gold, silver, copper, aluminium 
and most other metals have no significant magnetic property 
so are not detected.

The M-Scan is made to withstand heavy site use. 
The plastic housing is manufactured from high-impact ABS 
and the sensor tube is manufactured from lightweight aluminium.
There is a liquid crystal display and loudspeaker to give visual 
and audible outputs. There are four main user controls, on/off,
volume up/down, sensitivity up/down and an ‘erase’ button that
can be used to mask nearby disturbances allowing the user to
search near a steel fence, for instance. 

The sensitivity setting controls the effective depth that the 
M-Scan will find a ferromagnetic object. The M-Scan uses 
eight AA batteries in the sealed battery compartment giving 
approximately 100 hours of typical use (with high quality 
batteries). The standard kit includes a padded carrying case 
with shoulder strap.

The display shows the field strength in units of micro Tesla (µT).
There is an analogue bar graph showing signal strength, a four
segment battery indicator, and a flashing power line alert 
indicator. It also displays the North/South polarity 
of the detected object.
