Chapter 4 MXT Display
MXT Display Indication
The MXT 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
suiting the MXT to the application, Coin & Jewelry,
Relic, or Prospecting.
In all MODEs, the display will momentarily show a
software version and battery voltage upon first
turning the GAIN "on". The MXT operates on a
twelve volt battery system which with new quality
batteries will indicate 12 + volts. During searching
"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 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
significant indications on the display.
1. VDI = number - The VDI (Visual Discrimina-
tion 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
alloys and sizes.
