g. Detection Hints
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.
h. 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.
1. When the detector detects a buried target, continue sweeping the
search coil over the target in a narrowing side-to-side motion.
2. Make a visual note of the exact spot on the ground where the detector
beeps.
3. Stop the search coil directly over this spot on the ground. Then
move 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
beeps.
4. Repeat Steps 1-3 at a right-angle to the original search line, making
an "X" pattern. The target will be directly below the "X" at the point of
the loudest response.
Notes:
• If trash in an area is so heavy that you get false signals, slow your sweep and use shorter sweeps.
• Recently buried coins might not respond the same as coins buried for a long period of time because of oxidation.
• Some nails, nuts, bolts, and other iron objects (such as old bottle caps) oxidise and create a "halo" effect. A halo
effect is caused by a mixture of natural elements in the ground and the oxidation created by different metals.
Because of the metal mixtures, target signals might not be in a "fixed" position. This effect makes these objects
very hard to detect accurately. (See "Fine-Tuning the Detector").

4. Troubleshooting

If your detector is not working as it should, follow these suggestions to see if you can eliminate the problem.
