detector becomes more sensitive to the differences between large aluminum and gold pieces, for ex-
ample, but other valuable items such as coins and small rings, might be overlooked.
As you set DISCRIMINATION to higher levels, the detector first does not detect small pieces of
silver paper, then thick foil, and finally metal objects like cola pull tabs. Each time you change areas,
you must reset DISCRIMINATION.
As you sweep the search coil back and forth over the ground surface, you will recognize the differ-
ence between signals that occur at random and signals that are stable and repeatable. The key is to dig
only for those targets that produce a strong, repeatable signal. This will prevent you from wasting time
focusing on trash induced signals.
No metal detector is totally accurate. Many conditions influence the success of metal detection.
Among the factors that influence results are the angle at which the object rests in the ground, the depth
of object, the amount of iron the object contains and the size of the object.
To accurately pinpoint a target: 1. Once the detector detects a target that is buried, continue to
sweep the search coil over the target in a narrowing side-to-side motion. 2. Stop the search coil directly
over the spot on the ground. Then move the search coil straight forward away from you and straight
back towards you. Make a mental note of the exact spot on the surface where the detector beeps. Re-
peat these steps in an X pattern. The target should be directly below the X at the area where the loudest
response is heard.
Troubleshooting:
Problem Suggestion for Cure
False signals are being displayed Sweeping too fast or at the wrong angle.
Heavily oxidized metals are detected. Pinpoint the target
from several different angles. If the detector does not
display and sound the same signal each time, the target is
probabl-y heavily oxidized metal.
Once a target is found, the display
does not show the correct metal type May be more than one target in the area.
If target is heavily oxidized, an incorrect reading may
occur. This does not signify a problem with the detector.
It may be a type of metal which is not recognizable to the
detector.
