7. Indication the presence of a metal object in antenna area
The signal from a metal object, located in the area of the search antenna is
indicated by increasing the frequency of the sound signal.
Most weak signals, the operator can register are captured by doubling the preset
frequency of sound with "CRACKLE On/Off". This is perceived accurately
by the human ear and therefore it needs to be set very precisely, so that the
sound frequency without the presence of a signal to be only a few Hz (sounds
like crackles).
Each "signal" has "start" and "end". Golden mask Deep Hunter pro2 has very
well expressed "zone" indication signals from deeply buried metal objects in
search with frame. The length of this "zone" is a guide to the depth of the metal
objects. When this length is greater than the size of the search antenna and has a
characteristic peak in the middle - certainly refers to a deeply buried object. If
the signal is of a short duration (area), but captures only a central part of the
antenna, then also expected discovery of deeply buried metal object. Two-time
audible indication corresponding to the passage of the sides of the "frame" over
the metal object are sure indication of shallow buried small metal objects.
The use of round (hand) antenna gives a slightly different (more "short") signal
compared to the frame. This is due to the physical size of the antenna and must
be considered in determining the area where the expected opening of the metal
object.
After reaching a certain level of the signal (which will be observed in the
indicator "SIGNAL"), it will be carried out indication of the type of the metal
through the LEDs mounted in the indicating "SIGNAL". The red color
indicates a non-ferromagnetic metals and green - for ferromagnetic metals
(iron).
