Recommendations For Use; Useful Tips - Velleman CS130 Manual Del Usuario

• When desired, plug a headphone (not included) with a 3.5mm plug into the headphone jack [4].
• Set the speaker (or headphone) sound level using the volume button [2].
• When the low battery indication [1] lights up, replace the batteries to ensure detecting accuracy.
• Set the DISC button [5] about halfway.
• 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.
• When a metal object is detected, the detector produces a sound. For ferrous metals, the tone will
be low and the meter moves to the left while non-ferrous metals will produce a higher tone and
the meter moves to the right.
• 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.

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
Search coil sweeping hints
• Never sweep the search coil as if it were a pendulum. Raising the search coil while sweeping or
at the end of a sweep will cause false readings.
• Sweep slowly. Hurrying will cause you to miss targets.
• It is better to sweep the search coil from side to side in a straight line and keep the search coil
parallel with the ground.
• 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.
Pinpointing a target
• Accurately pinpointing a target makes digging it up easier. Accurate pinpointing takes practice,
and we suggest you practice finding and digging up small metal objects on your own property
before you search other locations.
