Swinging Speed and Target Identification
Target Distance
The device provides an estimated target distance according to the signal strength. In the
pinpoint mode, estimated target distance is shown on the display in cms (or inches - please see
below for details) while getting closer to the target.
Distance detection is adjusted presuming that the target is a 2.5cm (1'') coin. Actual distance
varies according to the size of the target. For instance, it will indicate more distance for a target
smaller than a 2.5cm (1'') coin and less distance for a larger target. Pinpoint procedure is not
intended for depth determination but location determination. Therefore, it is recommended
that the distance indicator on the display is used for determining the proximity to the target.
IMPORTANT!
If you want the target distance to be displayed in inches instead of cms please do
the following: While the device is
off
, press and hold the plus (+) and minus (-) buttons
simultaneously and turn the device on. ''US'' will be displayed. To switch back to cms, you need
to turn the device off and then repeat the above procedure. While the device is initializing, ''IS''
will be displayed.
RACER
is a detector with very high detecting speed. When you detect a target with
RACER
, you
should make wider passes instead of narrowing the sweeps and making quick sweeps over the
target like in other metal detectors, in order to receive an accurate ID from the target. If your
swinging speed is not correct, the device may not detect the target accurately and the target ID
numbers may bounce. Also, do not tilt the coil up or down while swinging and keep it parallel
to the ground.
Large or Near-Surface Targets
Targets which are near the surface may give multiple different signals to the device. If you
suspect a target near the surface, lift the search coil and swing it more slowly until a single signal
is received. Also, if there is a large target near the surface it may cause an overload in the search
coil and the device starts to generate a continuous sound which resembles a siren. “Saturation”
message is shown on the display simultaneously. In such a case, lift the search coil up until the
message disappears.
False Signals and Reasons
Sometimes, the device may produce signals which are similar to a target signal although no
metal target is present. There are various reasons for the false signals received by the device. The
most known ones are ground mineralization or rocks with high mineral content, surrounding
electromagnetic signals, operation of another nearby detector, rusted or corroded iron or foil in
the soil, gain or threshold values set too high.
Surrounding electromagnetic signals can be eliminated by reducing the gain. If another
detector is operating nearby, you may attempt to change the frequency or perform your search
at a distance where no interference occurs. For ground mineralization or rocks with high mineral
content, and gain and threshold set too high, please read the related sections (Ground Balance,
Rocks and Searching in Rocky Terrains, Metals Under Rocks, Gain and Threshold).
