higher the sound frequency. This is a very convenient mode for precise localization of the
location of an object.
To more precisely fix the location of the metal object in a strong and continuous signal can
be raised searching frame greater height above the ground. This will reduce the second
reflected signal from the metal object.
At a presence of de-balance, one has to press
"TUNE",
as at this, the searching coil has
to be close to the ground, at the distance of search to be.
If at work or in the initial setup, you hear irregular pulse sounds, they may be due to external
electromagnetic interference. In this case, turn potentiometer
DELAY
in a position where
this pulsation will disappear or detector will work considerably stable. Other metal detectors,
land cables, railroad tracks, radio transmitters, electric motors, water pumps etc. produce
strong magnetic fields that can interfere. If there are electromagnetic interference from
your searching area, lower the
THRESHOLD
, or change the current searching area. In
areas with complicate soil condition, try to set the
THRESHOLD
to proper position. Don’t
set the
THRESHOLD
to high position.
Or you’ll get a false result.
Also, low sensitivity usually used, when a large object is detected at a small depth in earth.
Then the signal is continuous in order to determine the exact place of the object it is more
convenient to use low sensitivity. Thus the signal from the detected object becomes much
shorter.
“
VEGA
” can sometimes react by small objects such as big coins or large caps, if they are on
the earth surface and within just pass over them, but then hear a short sound of a double
crossing of the two arms of the frame over the subject search!
“
VEGA
” work in switching mode with very low frequency - 350Hz, (same coil at one time
broadcast, a recorded following the adoption of a secondary object signal) searching is
necessary framework to move relatively slowly over the ground to enable to achieve good
depth of search. Should not be run when searching with the detector or to go very quickly to
prevent loss of depth!
2.1
Change of working mode - the device can work with
Dynamic
or
Static
mode.
Dynamic
mode we recommend when using small coils and make fast sweep over the
ground surface. Thus the signal from the detected object becomes much shorter. Also, fast
mode is appropriate if there is much trash in the ground where you use detector.
