Chapter 4 MXT 300 Display
MXT 300 Display Indication
The MXT 300 display and reference label below the
display provide a wealth of information about the
metal target. It is important, however, to understand
the display information should only be consulted
after a solid repeatable audio tone "beep" has been
located.
The MODE selection changes the type and content
of the information shown by the display better suit-
ing the MXT 300 to the application, Coin & Jew-
elry, Relic, or Prospecting.
In all MODEs, the display will momentarily show
a software version and battery voltage upon fi rst
turning the GAIN "on". The MXT 300 operates on
a twelve volt battery system which with new quality
batteries will indicate 12 + volts. During search-
ing "LoBat" will start appearing on the display at
8 volts and anything 8 volts and below are suspect
for replacement. If using rechargeable batteries 8
volts is surely the end of their performance. If you
are using quality alkaline batteries you do have a
reserve after 8 volts. The MXT 300 utilizes a low
voltage regulator. Quality alkaline batteries will
provide normal performance (in a pinch) well into
the LoBat indication.
Coin & Jewelry MODE;
The Coin & Jewelry MODE provides 5 different
signifi cant indications on the display.
1. VDI = number - The VDI (Visual Discrimi-
nation Indication) is a reference number dictated
mostly 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 al-
loys and sizes.
