screen in different categories from left to right. A 2-digit numerical
reading is also provided in the middle of the display for more precise
target identification. The DISCRIMINATION Mode requires motion:
sweep the searchcoil over the metal object.
4. Size and Depth of Buried Objects
When using the detector in the motion DISCRIMINATION Mode, the
relative depth of an object is displayed at the bottom of the display in
a 3-segment format: shallow, medium, or deep. A more accurate
depth reading is available in a no-motion mode, using PINPOINT or
ALL METAL Mode. These modes display target depth in inches. These
no-motion modes do not require the coil to be in motion to detect
metals. The ability to hold the searchcoil motionless over the target
also aids in tracing an outline of the buried object, or in pinpointing the
exact location of the object using techniques described in the
pinpointing section.
5. Electromagnetic Interference (EMI)
The searchcoil produces a magnetic field and then detects changes in
that magnetic field caused by the presence of metal objects. This
magnetic field that the detector creates is also susceptible to the
electromagnetic energy produced by other electronic devices. Power
lines, microwave ovens, lighting fixtures, TVs, computers, motors,
etc…. all produce EMI which can interfere with the detector and cause
it to beep when no metal is present, and sometimes to beep erratically.
The SENSITIVITY control lets you reduce the strength of this magnetic
field, and therefore lessen its susceptibility to EMI. You may want to
operate at maximum strength, but the presence of EMI may make this
impossible, so if you experience erratic behavior or “false” signals,
reduce the sensitivity.

4. # OF TONES
While the # OF TONES line is highlighted, use
and
to program
the number of different audio tones.
Different target categories are identified by different audio tones in order
to give you the fastest real-time reference while searching. Most
experienced users become familiar with the tones and search without
always looking at the display.
Use this selection to program the number of audible tones the detector will emit.
The default setting is 4 tones.
If you program less than 4 tones, the tones, by category, are as outlined here:

5. VOLUME
While the VOLUME line is highlighted, use
and
to change the
speaker volume.
The default volume setting is 10. Maximum is 10.
Minimum is 0 (volume off). At levels 1, 2 and 3, high tones will be
inaudible or barely audible.
The speaker volume will diminish as battery voltage drops. For
maximum speaker volume, use 1 or 2 tones, as the low and bass tones
generate the loudest sounds.
Volume can be set while in either the DISCRIMINATION or ALL METAL
Modes, but only one setting applies to both modes. Volume in the two
modes cannot be set independently.
