Double-D Coil Noise Cancel
Procedure
Generally, a Double-D coil should only be
used if noise cannot be managed by using a
Mono coil with the Noise Cancel Procedure.
This procedure can be used in areas that
have known high levels of EMI or very
conductive (salty) soils.
START 
1. Connect the GPX 14™
Double-D coil.
2. Hold the coil 100 mm
(4 in) above the ground.
100 mm (4")
3. Turn the detector on.
4. Set the Double-D mode
to EMI Cancel.
Long-press for at
least 2.5 s
5. Hold the coil still above
the ground and assess
noise levels.
 Begin detecting.
 If the detector is still noisy, continue
to the next step.
6. Noise Cancel.
 Begin detecting.
 If the detector is still noisy, continue
to the next step.
7. Reduce the
sensitivity level.
 Begin detecting.
 If the detector is still noisy, change to
an Auto sensitivity setting (Auto or
Auto+).
