Multi-Frequency - AKA Signum MFT 7272? Instruction Manual

Селективный металлодетектор «Сигнум MFT» 7272М. Руководство по эксплуатации.
There is no need to use this algorithm for a definitive low-pitched signal, i.e.
when the subject is clearly iron. Remember though, to monitor the signal rating level of
the target.
It should be pointed out that this mode does not apply to general searching, but
only to help clarify the type of metal of a non-ferrous response and to decide on the need
to dig.
The S Algorithm has virtually no effect on the hodograph display of non-ferrous
targets
It should also be noted that when increasing the surface area of iron objects the
effectiveness of the S-algorithm decreases.
To switch to this mode, use the button
and ST sensitivity and volume should be displayed .
To return to the main search mode press the button again.

MULTI-FREQUENCY

You may be interested to know that most of the detectors manufactured in the
world will have a comparable sensitivity, for example, a brass disk with a diameter Ø25
mm and copper disc at Ø50 mm, despite the fact that the second object is much larger. It
is also known that small targets (coins) are detected better at higher coil excitation
frequencies.
The fact is that by the virtue of certain physical laws each target class has its own
optimal frequency at which the sensitivity to these targets are maximized. In order to give
the unit the opportunity to search effectively for both large and small targets, many
manufacturers produce 2, 3 or 4-frequency metal detectors. The Signum MFT 7272M
allows you to work with coils with the operating frequencies from 1 to 30 kHz, thus
maintaining acceptable sensitivity to almost any type of target.
The metal detector can be equipped with the following sensors: 15DD -3 (7) kHz,
9.5 x12, 5DD - 7 (3, 14) kHz, 10DD - 7 (3) kHz 6h10DD - 7 (14) KHz.
What could be the practical guidelines for choosing a coil with a different
operating frequency?
3 kHz can be successfully used on
non-ferrous targets as well as the spoils of war.
7 kHz –Is the average universal frequency for a wide range of applications. You
can search for both medium and small coins as well as the spoils of war. This frequency is
convenient for terrain reconnaissance.
14 kHz - Frequency optimized for small and medium-sized coins especially
when the latter are located on edge. This frequency is the best choice for hunting on the
saltwater beach.
