SEARCHING
7. Search in a methodical manner sweeping in a
tight semicircle. Pay close attention to where you’re
going and where you’ve been.
8. TAKE YOUR TIME. If you walk too fast you can’t
overlap your sweeps and you’ll miss a lot of
ground.
If you sweep too fast, you’ll lose sensitivity and miss
the faint tone which will disappear as soon as the
coil is raised.
9. The diagram below shows the search coil
detection pattern and how it is affected by sweep
speed, discrimination level and overlapping sweeps
in the Search mode.
Figure 5. “sweeping”
the search coil. Keep
the search coil parallel
and close to the
ground at all times
