2. Blocks- A series of 16 blocks appear along the bottom
portion of the display and line up with the indications on the
reference label below the display. It is important to note
these blocks are a different separate opinion compared to
the VDI number and they may or may not agree. There is
significance to how these blocks appear. A full block indi-
cates the MXT Pro is confident of indication. A half block
indicates the MXT Pro is not confident but is making an
educated indication. A quarter block indicates the MXT Pro
is not confident at all, guessing based on what little informa-
tion the target is producing.
3. Text/ Labels- The most common metal target (or tar-
gets in some cases) to indicate that particular Block is listed
on the display as well as referenced in an expanded format
on the label below the display. If two targets are listed the
first to be listed is the most common and the second listed
slightly less common than the first.
4. Depth Indication- Trigger (on handgrip) squeezed
and held or pushed forward to lock, the display indicates the
depth of coin-sized metals. Starting at 12 inches and indi-
cating in descending order (as the target gets closer to the
bottom of the search coil), the DEPTH = 12 (twelve inches
deep) provides not only an aid in better locating the target in
the ground (how deep you will need to dig) but also clues as
to if the metal target is likely worth digging. For example if
the display is unsure (quarter block indication), is indicating
in the FOIL range, and the depth reads deep 6 to 12 inches,
you should dig the target. Only the heavier more valued
targets get deeper into undisturbed ground. If the display
reads unsure (quarter block), indicates in the FOIL area,
and the depth reads shallow 0 to 2 inches, the target is most
likely not worth digging. Foil will not sink deeply into undis-
turbed ground. Targets that indicate depth readings from 3
- 5 inches are not as predictable. The shallower Depth read-
ings typically have fuller Blocks to warrant digging. A large
target that is very deep will tend to provide a small pinpoint
area as well as an inaccurate shallow depth indication. Use
this to your advantage; a shallow depth indication (0-1 inch),
having dug six inches and not found the target, is a larger
deeper target.
