Chapter 4 MXT Pro Display
MXT Pro Display
The MXT Pro display and reference label below the display
provide a wealth of information about the metal target.
Important; consult the display information only after a solid
repeatable audio tone “beep” has been located over multiple
search coil passes.
The MODE selection changes both the audio sound presen-
tation and the type and content of the information shown on
the display, better suiting the MXT Pro to the application,
Coin & Jewelry, Relic, or Prospecting.
In all MODES, upon first turning the GAIN “on” the display
will momentarily show a software version and battery volt-
age, followed by the Mode and Tone selection.
Turning off and on, the MXT Pro will always return to the
original factory default Tone selections;
1. Coin & Jewelry = Tone ID- Up to seven
tones depending upon Discrimination control setting, with
iron (if accepted) the lowest pitch and +95 the highest pitch
tone. Press “music notes” to turn ON/OFF Tone ID. When
OFF all accepted targets indicate with the same basic pitch
or tone.
2. Relic = 2 Tone- Rejected targets (those below the
current Discrimination setting) produce a lower pitch tone;
accepted targets (those above current Discrimination set-
ting) produce a high pitch tone. Press “music notes” Tone ID
to select among two other tone options for the Relic mode;
Iron ID (all iron low tone, all non-iron high tone) Discrimina-
tion Control disabled, or, 1 Tone (above current Discrimina-
tion setting high pitch tone, below discrimination setting
audio suppressed, iron if accepted = low pitch tone).
3. Prospecting = Iron Grunt ON- Targets with
80% and greater probability of being iron produce a unique
grunt tone. Press “music notes” to turn ON/OFF. When OFF;
all targets produce the same basic VCO audio varying only
upon their size or signal strength.
Backlight will always revert to OFF during ON/OFF cycles.
The MXT Pro operates on a twelve volt battery system.
which with new quality batteries will indicate 12 + volts. Dur-
ing searching “Lo Bat” will start appearing on the display at 8
volts and anything 8 volts and below are suspect for replace-
ment. If using rechargeable batteries 8 volts is absolutely
the end of their usable performance. Use after 8 volts can
damage rechargeable batteries and the MXT Pro will not
perform normally. If you are using quality alkaline batteries
you do have a reserve after 8 volts. The MXT Pro utilizes a
low voltage regulator. Quality alkaline batteries will provide
normal performance (in a pinch) well into the Lo Bat indica-
tion.
Coin & Jewelry MODE- The Coin & Jewelry
MODE provides 5 different significant indications on the
display.
1. VDI Number - The VDI (Visual Discrimination Indica-
tion) is a reference number dictated by the metals targets
exact alloy, size, and shape. The reference label below
the display provides a comparison of known targets and
their common VDI numbers. Like targets produce like VDI
numbers. Similar targets produce similar VDI numbers. And
different targets produce different VDI numbers. Different
metal targets, however, may share the same VDI numbers
based on their electrical characteristics. VDI numbers from
-95 to +94 are available and cover the entire range of alloys
and sizes.
