Search Method - Nexus STANDARD MP V3 User Manual

To achieve the best ground balance tuning, it is essential that the
coil be held parallel to the ground surface at all times during the
procedure.
In highly mineral soil conditions the use of Mineral Control may be
necessary to apply to tune the detector in stable operating
condition.
* After every change in Mineral control levels ground balance
must be done again.
The use of mineral controls will lead to some loss of depth.
Setting the desired Discrimination level is done by rotating the
Discrimination knob clockwise to INCREASE the discrimination
level and REDUCE the sensitivity to ferrous (iron); higher than
necessary settings will result in desired targets being missed.
Rotating the Discrimination knob anticlockwise will DECREASE
the discrimination level and INCREASE the sensitivity to ferrous
(iron) targets.
Tip: In general, an effective method of setting the Discrimination
level, suitable for most search conditions, is by passing a rusty
iron nail (about 50 mm long) close to the search coil. Rotate the
Discrimination knob clockwise until the iron nail is rejected from
the RGB meter in every possible position against the coil. After
this procedure check if small non-ferrous targets are detectable
without loss of depth.
Finally, check again the threshold for audible level and volume
for comfortable level.
The Nexus Standard MP V3 is now set up for the particular site
conditions and it is ready for use.

With the Nexus Standard MP V3 set up and ready, the coil should
be swung smoothly from side to side, a little above the ground
surface. The sweep speed should be moderate to slow and never
9.
