4. Repeat Steps 1-3 at a right-angle to the original searchline, 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").
