sound. This is done with change in the parameter "Thresh. For this purpose, through the buttons
"◄ and ►" desired value can be selected from „0“ to „20“. The lower the value of „Thresh“,
the greater the sensitivity of the device. For instance, if at a balanced device the constant signal
from soil is "1" and we have chosen for "Thresh" a value of "1", then a sound signal is going to
appear when the general signal becomes greater than "1". If for "Thresh" a value of "6" has
been chosen, then the device is going to react with sound at a considerably stronger signal – value
greater than "6". Greater values of "Thresh" can be selected if the general signal from the
background of soil changes within wider limits, in order the device to be calm, aiming a sound
signal not to be produced which is not due to detected metal, but the greater the value of
„Thresh", the more sensitivity of the device decreases!
At a presence of de-balance, one has to press shortly "ON – OFF / CLEAR", as at this,
the searching coil has to be close to the ground, at the distance of search to be. Continuous
pressing of "ON – OFF / CLEAR" for more than 4 sec will turn off the device, as this is
accompanied by 3 short sound signals.
Should within the range of the coil there falls an object, it produces a signal which is
displayed on both indicators ID1 and ID2 and on the indication „Level“ of the intensity of the
signal. Should this signal is louder than the threshold chosen of the sound „Thresh“, a sound is
heard with a frequency which depends on the sound level. The greater the signal from an object,
the louder the frequency of sound. This is a very convenient mode for precise localization of the
location of an object.
Pinpointing a Target
A good method for pinpointing is "X-ing" the target with the search coil. Remember that the
target's response sound is always greatest when the target is directly under the center of the search
coil. To "X" a target, sweep the search coil over the target from side to side and then from front to
back until you can identify the center of the X— the spot on the ground where the target response
sound is the greatest. Pinpointing a target in Discriminate Mode is probably best done by "X-ing"
as well. Remember that the detector will beep just as the target passes under the center of the
search coil. Slowing the sweep speed down will help you pick out the center of the X, but
remember that the search coil must always be moving slightly for target detection.
Another easy method is to sweep the coil from side to side across the target in very short sweeps
as you slowly move forward and backward across the target. Slow down the sweep rate and
