c. 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").
6. Troubleshooting
If your detector is not working as it should, follow these suggestions to see if you can eliminate the problem.
PROBLEM
The detector displays or sounds false signals
The display does not show the correct metal
type when the detector finds a target or the
detector sounds more than one type of tone
when it finds a target.
CS100
You might be sweeping the detector's search coil too fast or at the
wrong angle. Sweep the search coil more slowly and hold the
detector correctly. See "Testing and Using the Detector" and
"Pinpointing a Target".
The detector might sound a false signal if it detects heavily oxidised
metals. Try pinpointing the target from several different angles (see
"Pinpointing a Target"). If the detector does not display and sound
the same signal each time, the target is probably heavily oxidised
metal.
There might be more than one target in the area you are searching.
The target might be a type of metal that the detector does not
recognise.
If the target is heavily oxidised, the detector might not display the
correct metal type. This is not a malfunction.
