The main search mode of the device is dynamic, i.e. object detection
occurs only with constant movement of the sensor.
To determine the exact location of the detected object, the device has a
static mode of operation.
The device has two types of indication of object detection:
- sound programmable multi-mode
- visual (hodograph, VDI index, rating (level) of the PC signal)
The device implements two independent search channels: RT and ST.
The RT channel (real time, RT) is a detection channel and
operates in real time, i.e. sound indication is issued synchronously with
the movement of the sensor over the object. The sound indication in this
channel is a single-tone signal, the volume and frequency of which can
change as the object approaches the sensor. The duration of the sound
from the object can be judged on its approximate size.
When the signal from the object in the RT channel exceeds the level of
the set threshold value, the ST channel begins to work.
The ST channel (short tone, ST) is an object type identification channel.
If the threshold level of the signal from the object is exceeded, it is iden-
tified in the ST channel, then a short sound signal of the corresponding
tonality is issued, and the hodograph is displayed on the display screen.
The frequency of the short tone indicates the type of object (high tones
- non- ferrous metal, low tone - ferrous metal). The number of tones is
set by the user (by default - 4 tones for non-ferrous metals and 1 tone for
ferrous metal).
Each channel has its own independent sensitivity adjustment.

frequency, it is necessary to re-balance the
