Sensitivity Control level. Reducing the Sensitivity Control level in order to gain stability will not cause
an enormous loss of depth. It will give a better ability to see small targets, effectively yielding better
depth.
Operating in the Discriminate Mode
Before beginning to search in the Discriminate Mode, perform the SuperTRAQ Ground Adjust procedure
outlined above.
In the Discriminate Mode of operation, the Threshold sound will no longer be heard, since the LOBO
SuperTRAQ uses Silent Search Discrimination. The Discrimination Level Control will set the effective
good/bad rejection level desired. See the figure below, Discrimination Level Settings, to determine the
approximate setting to reject the unwanted targets. The searchcoil needs to be moving slightly with
respect to the target in order to find targets in Discriminate Mode.
The Sensitivity Level control should be kept as high as possible without causing unstable operation or
false target signals. The MAXBoost area (denoted by the orange colored area above 10) can be used, but
in some conditions the detector may become too noisy or erratic for good operation. Turning the
Sensitivity Level control down slightly to restore stability will again give an apparent increase in depth
by making the detector's response easier to discern without having to separate the "good" signals from
the "bad."
FIELD USE PINPOINTING
Pinpointing with the LOBO SuperTRAQ can be accomplished easily in either the All Metal Mode or the
Discriminate Mode. The detector also has a pinpoint position on its Mode Selection Switch labeled
PINPOINT, which may make pinpointing even easier. In this position, the automatic threshold tuning is
eliminated, and the gain is reduced, so it will be easy to tell where the loudest target response is located.
Move the searchcoil back and forth and forward and backward until you get the loudest audio response.
The target should be directly below the searchcoil center at the time of loudest response. If the audio
response is at maximum over a very broad range of movement, momentarily stop the searchcoil in the
center of this area and release the pinpoint switch until the detector retunes itself back to threshold. Then
press the switch back to the pinpoint position and continue moving the searchcoil to find the loudest
response. This retuning in the middle of the loud area will greatly reduce the area of response.
You may have better luck pinpointing by "X-ing" the target. To do this, sweep the coil from side to side
over the target until you determine the coil position when the loudest response is present. Make a mental
note of this position, which will give you one of the lines of the X you are about to make. Turn 90
degrees to this line and sweep back and forth until you again get the loudest response. The position of the
coil at this time should give you the other line, and the target is at the center of the X formed by these
two lines. Dig where the two lines intersect.
Recovering Your Target
Even with the extreme power of the LOBO SuperTRAQ, pinpointing isn't enough to recover your target.
