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.
10. Recommendations for Use
•
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.
o
the depth of the object.
o
the amount of iron in the object.
o
the size of the object
o
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.
•
Sometimes, targets are difficult to accurately locate due to the sweep direction. Try changing your sweep
direction to pinpoint a target.
•
Follow these steps to pinpoint a target.
When the detector detects a buried target, continue sweeping the
o
search coil over the target in a narrowing side-to-side motion.
Make a visual note of the exact spot on the ground where the detector
o
beeps.
Stop the search coil directly over this spot on the ground. Then move
o
the search coil straight forward away from you and straight back
toward you a couple of times.
Make a visual note of the exact spot on the ground where the detector
o
beeps.
Repeat Steps 1-3 at a right-angle to the original search line, making
o
an "X" pattern. The target will be directly below the "X" at the point
of the loudest response.
