d. Pinpointing
In the automatic threshold off position, a surface target can appear to be very large, which is normal. Now the target
must be 'narrowed down' to determine its location more accurately. Start to pass over the target from one direction,
when the meter goes 'off scale' press the thumb set control briefly to bring the meter back on scale. Continue to
cross the target in the same direction and repeat the pressing of the switch. There will be a point where the meter
reading and speaker tone will 'peak out' and start to drop back down. It is at this peak that the front loop is over the
buried metal object. Pressing and releasing the thumb set control will cause the target to appear to shrink, making
pinpointing easier. The automatic threshold allows the pinpointing to take place automatically.
e. Locating Caves and Other Voids
1. Set the mode switch to the CAVE position and set the signal balance, ground balance and threshold controls to
the normal range. The signal balance control may be readjusted to optimise for the location you are hunting in just
as described under "6a. Ground Balance Metal Mode" on p.3.
2. The automatic threshold may be on or off, whichever gives you the smoothest performance and is the most
comfortable. If there are rapid ground changes and there is difficulty maintaining a threshold, the best choice is to
activate it. If you are an experienced user, you may prefer to leave it off. Always keep the device at the same
distance from the surface in order to avoid false indications.
It is not recommended that you search in this mode unless you are looking for changes in ground density.
Operation in the CAVE mode will produce a positive sound for all non-ferrous metals such as gold or silver, and will
produce the same response for voids, such as a cave. When a ferrous target such as iron is encountered, or when
there is heavy iron mineralisation, the sound will respond by going quiet.
Since the ground balance is not affected in the CAVE mode, leave the ground balance control at the normal range.
Because ground mineralisation is not cancelled, the CAVE mode does not achieve the same depth as the METAL mode.
7. The Importance of the Right Approach
Treasure hunting can be a profitable and rewarding activity for the patient and diligent user. Time spent researching
to locate a worthwhile site for a search can become time wasted if your search is hasty and erratic. Plan your
approach to each individual site beforehand. Working slowly and methodically will enable you to hear the faintest of
signals, thereby increasing the number of finds. Keep the detector head as close to the ground as possible. The
antenna should 'iron' the ground in order to keep the loss of detection range down to a minimum.
The technique of getting the best out of your detector is not learnt overnight. You need as much experience as
possible to learn to recognise every kind of signal.

8. Storage and Maintenance

Store your detector in a warm and dry environment when not in use. Remove the batteries to prevent leakage if the
device is not be used for a length of time. Clean the exterior parts of the housing whenever you have used your
detector in a hostile environment (salt water, sand, etc.).
Make sure that the antennae fit on the shaft stubs in a snug manner.
9. Troubleshooting
a. The Detector is not Operating
• Check the condition of the batteries using the meter and replace them if necessary.
• Interchange the batteries and check if the connections are correct and secure. Battery life can vary tremendously
between makes: your "new" batteries may already lack the power to run your detector.
• Make sure that the antennae are properly attached to the control box.
