Chapter 4 M6 Display
M6 Display
The M6 display and reference label below the
display provide a wealth of information about the
metal target. The display information works best
after the solid repeatable audio "beep".
The display will momentarily show a software
version and battery voltage immediately after the
SENS knob is turned "on". The M6 operates on a
twelve volt battery system, new quality batteries
will indicate 12 + volts. After 35 to 40 hours of
operation,
"Lo Bat" will start appearing on the display at 8
volts and below. If using rechargeable batteries 8
volts is the end of their performance. If you are
using quality alkaline batteries you do have a small
reserve after 8 volts. Quality alkaline batteries will
provide extended normal performance well after the
"Lo Bat" warning.
The M6 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 metal targets exact alloy, size, and
shape. The reference label below the display pro-
vides a comparison of known targets and their
common VDI numbers. Different metal targets may
share the same VDI numbers based on their electri-
cal characteristics. VDI numbers from -95 to +94
are available and cover the entire range of alloys
and sizes.

The M6 (hand grip toggle forward position) has
seven distinct tone ranges that correspond
directly to the types of targets indicated on the
display. The lower the tone, the lower the VDI
number.
