can be a procedure which may need to be done every few feet. Fortunately, the LOBO SuperTRAQ has a
micro controller based Ground Tracking feature which essentially eliminates this tiresome procedure.
The LOBO SuperTRAQ's procedure is very simple and takes only a few seconds to do. It should be done
each time you use the detector, no matter which mode of operation you plan to use.
Once the LOBO SuperTRAQ is properly ground balanced, it tracks the mineral conditions automatically
as you hunt in the All Metal Mode. The automatic tracking is disabled when the detector is used in the
Discriminate mode.
SuperTRAQ Ground Adjust Procedure
Select a spot on the ground where you feel certain there are no metal targets. You can search for
this spot in the all metal mode prior to performing this procedure.
1.
With the detector operating in the All Metal Mode, set the Ground Selection Switch in the Normal
Soil position and the Sensitivity Control at 10.
2.
Raise and lower the searchcoil (from about one foot off the ground down to about two inches
above the ground) fairly rapidly until you suddenly hear no further changes in the Threshold
sound as the coil is raised and lowered. Typically the LOBO SuperTRAQ will do the ground
balance in about three or four up and down motions. The detector is now properly ground
balanced.

Note
: The Ground Selection Switch should always be left in the Normal Soil position since that is where
it gives the best ground balance and smoothest operation. If you cannot ground balance in the Normal
Soil position, then move the switch to the Alkali position. This will give the circuitry a much broader
window for ground balancing, but will yield rougher ground balance and increase the chances of small
metal targets being rejected by the circuit. The Black Sand position should only be used when absolutely
necessary since it cuts the gain of the input amplifier, which reduces the detector’s sensitivity. If it is
necessary to use the Black Sand position, the decreased gain will yield a better chance of finding a good
target in the black sand.
Selecting the Proper Operating Mode
The choice of which operating mode to use is really quite simple. If you intend to hunt for gold nuggets,
you need to use the All Metal Mode. If you are interested in hunting for relics or caches which may be
partially or completely ferrous in nature, you can use either mode, but if Discriminate is used, keep the
Discriminate Level Control set at the min position so that ferrous targets are detected. If you want to hunt
for any particular class of items, but don’t want to detect other unwanted items, you must use the
Discriminate Mode. The Discriminate Level Control can be used to adjust the detector's response to
wanted/unwanted targets.
Operating in the All Metal Mode
Before beginning to operate in the All Metal Mode, perform the SuperTRAQ Ground Adjust procedure
outlined above.
When operating in the All Metal Mode, the SuperTRAQ circuitry will automatically keep the detector's
ground balance set for maximum mineral free performance. It will resist tracking on small metal targets,
but if for some reason the detector does become unbalanced, the simple act of raising and lowering the
searchcoil several times will restore the ground balance.
The Ground Selection Switch should always be left in Normal Soil position unless the detector will not
ground balance or you are operating in an area of heavy black sand. If the detector cannot properly
ground balance, put the switch in the Alkali position. This will increase the amount of range the
SuperTRAQ circuitry can balance out, but performance may be slightly less than when in Normal Soil
position. The Black Sand position will cut the electronic gain of the input amplifier to prevent distortion
due to the amplifier saturating from the large input signals caused by the black sand. It will decrease the
overall sensitivity of the detector, but will make it much easier to find a target located in black sand.
The Sensitivity Control should always be at the highest level possible to yield smooth operation. If the
detector becomes somewhat unstable at maximum sensitivity, stability can be restored by lowering the
