8. Pinpointing Tips
Whenever your detector locates a target, locating
it precisely will enable you to recover it by digging
the smallest hole possible. This is accomplished by
pinpointing. Note that pinpointing with a DD searchcoil
is somewhat different than pinpointing with a mono
searchcoil. The instructions for each are below.
Pinpointing with Power DD Searchcoil
The Power DD coil has a narrow detection field
pattern that runs front-to-back underneath the center
section of the coil, so always detect by sweeping the
coil in a side-to-side motion.
First, slowly scan the searchcoil from side-to-side
over the target area, noting the location where the
loudest signal occurs. Once the area with the loudest
signal has been identified, position yourself 90° from
the target area and again scan side-to-side to pinpoint
the target's exact location.
For targets on or close to the surface, start behind
the target's suspected location and scan the area
using short side-to-side sweeps while moving forward
until the target is exactly pinpointed underneath the
tip of the coil.
