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.
Make a visual note of the exact spot on the ground where the
detector beeps.
2.
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.
3.
Repeat Steps 1-2 at a right angle to the original searchline,
making an “X” pattern. The target should 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 speed 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) oxidize 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”).
