• 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").
7. Care and maintenance
Wipe the detector with a damp cloth occasionally to keep it looking new. Do not use harsh
chemicals, cleaning solvents or strong detergents to clean the detector.
• Modifying or tampering with the detector's internal parts can cause a malfunction and might
invalidate its warranty.
• The search coil supplied with the detector is waterproof and can be submerged in either fresh or
salt water. However, do not let water enter the detector's control housing. After using the search
coil in salt water, rinse it with fresh water to prevent corrosion of the metal parts.
8. Troubleshooting
If your detector is not working as it should, follow these suggestions to see if you can eliminate the
problem.
PROBLEM SUGGESTION
The detector displays or
sounds false signals 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.
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.
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.
