Hold the search coil [I] about 1 foot (30cm) from the ground and press and hold the trace
•
button on the handle [B].Turn the TUNE button [3] until the analogue meter [6] points to 0
(zero). Release the trace button.
Note: Press the trace button whenever the detector is drifting away from the sensitivity setting, e.g.
when moving from dry ground to wet ground. This returns the meter to zero.
Slowly sweep the search coil over the desired area. Refer to §10.
•
Slowly turn the discrimination control [5] clockwise. The further the button is turned, the more
•
metals will be rejected. Refer to §6 how it works – phase shift for more information.
Note: press the trace button after each adjustment.
8.1 Interpreting signals
The detector produces a signal as soon as it is switched on.
•
The signal varies according to the detected object.
•
For ferrous metals, the tone will be low and the meter moves to the left.
•
• Non-ferrous metals will produce a higher tone and the meter moves to the right.
Oscillating Signal
An oscillating signal is caused most often by outside sources such as fluorescent lights, radios,
•
power lines and the proximity of other metal detectors. There's not much you can do about it.
Intermittent Signal from Speaker
An intermittent signal can have several origins:
This could be due to poor battery connections. Make sure the batteries are securely clipped in
•
place.
A radio transmission from a passing taxi or another vehicle using radio transmitter equipment.
•
The speaker may have come loose. Have your dealer fix the speaker back into place.
•
False signals
The detector responds with a signal when it detects most valuable metal objects. If a signal does
•
not repeat after you've swept the search coil over the target a few times, the target is probably
junk metal.
False signals can be caused by trashy ground, electrical interference, or large irregular pieces of
•
junk metal.
False signals are usually broken or non-repeatable.

9. Recommendations for use

Treasure hunting can be a profitable and a rewarding hobby, if approached in a patient and
•
diligent manner. Time spent researching to locate a worthwhile search site can be time wasted if
your search is hasty and erratic. To achieve maximum results, it is important to decide on your
approach to each particular site, before the actual search.
Tactics will be decided by the type of site – it is more profitable to scan a small area thoroughly
•
than to conduct a haphazard search of the total site. However, when the site is too far away for
you to make several return visits, a plan should be adopted which gives maximum site coverage,
but at the same time allows some detailed search.
It quite often happens that where one find is made, other finds will be made in the immediate
•
vicinity. Accordingly, places having the highest density of markers represent the most likely
spots for further finds.
• The detailed search is made by marking out strips of a width determined by the sweep of the
detector, and moving forwards the approximate diameter of the search head after each sweep
until the 'strip' has been completely covered. The adjacent strips are covered in similar manner,
until the complete area has been thoroughly searched.
Wooden pegs and string are ideal for marking out areas, but very often natural landmarks such
•
as trees, rocks and plants can with practice, prove just as effective.

Useful tips

No detector is 100 percent accurate. Various conditions influence metal detection. The detector's
•
reaction depends on a number of things:
• the angle at which the object rests in the ground.
the depth of the object.
•
the amount of iron in the object.
•
• the size of the object
