Testing the Detector
1. Remove all rings and your wristwatch and place the search plate on a
wooden table.
2. Set the volume control to 11 and turn the DISCRIMINATION control to
the middle.
3. Move a metal object about 5 cm above the seeker disc and observe the
needle deflection.
When set correctly, you will hear a warning tone and the needle will deflect.
For ferrous objects, the needle will strike to the left and for non-ferrous metals
such as precious metals, brass, copper, etc., the needle will strike to the right. If
the needle does not deflect, check that the seeker disc is properly connected
and repeat the detector adjustment (as described in the previous paragraph).
Use in practice
Important: First obtain permission from the landowner before you begin
your search. Make sure that there is no regulation that prohibits searching
the area. Do not damage other people's property. Do not leave any traces
and refill holes you have dug. Take any waste you have found with you
and dispose of it in accordance with the regulations. Do not leave it lying
around.
1. Select a suitable spot, e.g. a
lawn, where there are no metal
objects in the ground.
2. Place a metal object, such as a
coin, on the ground to track it
down for practice.
3. Press the red knob and slowly
turn the TUNE knob until the
needle of the coil knife is in the
middle position.
4. Now move the seeker plate
evenly back and forth at a height
of 50 cm above the ground.
