to Medium, or from Medium to High.l While searching position the coil
about 2” above and parallel to the ground surface. Raise suggested
operating heights for the standard coils are:
9" coil: 2" minimum above the ground surface
6” coil: 1,5” minimum above ground surface
4” coil: 1” minimum above ground surface
Make sure that the coil is swung evenly over and parallel to the ground
surface and that the coil does not rise at each end of the swing. Cover the
ground in smooth, parallel swings to ensure maximum ground coverage.
Good non-ferrous targets will give a clear, well-defined, two-way,
repeatable audio signal. Ferrous targets will give a ‘clicking’ audio response
or an indistinct and erratic response.
Pinpointing
is carried by simply X-ing the coil across the signal. The
position where the signals are strongest indicates where the target is
buried. As with all detectors, when targets are of complex shape or are
located at an angle in the soil, pin-pointing may not be entirely accurate.
Tips
Sweeping the coil too fast over the ground will result in signals being
missed. It must always be remembered that no detector can find what is
not there – nor can any detector give a signal unless the coil is passed
directly over that target.
If you are on a productive site and know how to properly adjust the detector
using the Coronado Groundfix will guarantee good finds!
There will always be sites on which any single detector does not work to
peak efficiency. All detectors and sites are different and a particular
combination of frequency and filtering might be best on a specific site.
Site conditions will significantly affect depths and performance. Heavily
furrowed or broken ground or thick stubble are especially difficult. Sites
where the ground conditions vary to a considerable degree may require the
fixed Ground Balance level to be changed for best results.
Care
All Nexus metal detectors are precision instruments and require careful
handling to ensure they remain in good working order.
