GENERAL INFORMATION
Metal detector SIGNUM MFT 7272M is designed to search for and identify metal
objects in the dielectric (dry sand, wood, etc.) and low conducting media (soil, brick walls,
etc.).
Some applications of use are:
•
Criminal;
•
Engineering;
• Housing and community services, construction and fire-fighters to search
for underground utilities, pipelines, cables, manhole wells etc.
• Archaeology and treasure search.
The device is designed to operate under the following conditions:
-
Ambient temperature from -20 up to +50°c (-4 to 122 F);
-
Relative humidity up to 98 per cent at temperature of 25°c (77 F);

GENERAL DESCRIPTION
The Signum MFT 7272M is an eddy current selective metal detector that works
on the principle of induction balance. The main distinguishing feature of this model is the
use of its original software and hardware. Our multi-frequency technology (MFT) allows
the use of any search coils manufactured by us, regardless of their operating frequency
(Hz). That is, the device itself will make adjustments and calibrate to the selected coil.
The device uses the original technology of signal processing sensor-technology
space and harmonic filtering (SFT), minimizing the hindering effect of ferrous soil
(salinity) and, thereby, increasing the reliability of the identification of deep and
small objects.
Basic search mode – Dynamic search mode, i.e. detection of an object occurs with
constant motion of the search coil.
To pinpoint the exact location of the detected object the device has a static mode of
operation (Pinpoint).
The device has 2 methods for identifying the object detected:
-Audio programmable multi-mode,
-Visual (Hodograph, VDI value, rating (level) signal-RS).
The device has two independent search channels: RT and ST.
The RT channel (real time) works in real time, i.e. sound indication is given
simultaneously with the movement of the search coil over the object. Sound indication in
this channel is a single-tone signal, volume and frequency of which can change when an
object approaches the search coil. Also using the duration of the tone we can get an
estimate of size of the target detected.
When the received signal from an object exceeds the specified RT threshold, the
channel generates the ST audio or short tone.
Channel ST (short tone) is the audio identification channel for the type of object
detected. When the received signal exceeds the threshold of the RT channel the detector
issues a short audio tone (ST), and the screen displays the hodograph (vector time curve) of
the detected object.
The frequency of the short tone indicates the type of object detected (high tones –
non ferrous metal, low tone - ferrous metal). The number of tones can be specified by the
user (the default is 4 tones).
