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 indicates the
MXT is confident of indication. A half block indi-
cates the MXT is not confident but is making an
educated indication. A quarter block indicates the
MXT is not confident at all, guessing based on what
little information the target is producing.
3. Labels - The most common metal target (or
targets 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 hand grip)
squeezed and held, the display indicates the depth
of coin sized metals. Starting at 12 inches and
indicating in descending order (as the target gets
closer to the bottom of the search coil) the DEPTH
= 12 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 undisturbed ground.
Targets that indicate depth readings from 3 - 5
inches are not as predictable.
5. PP Blocks - Trigger (on the hand grip) squeezed
and held, the PP blocks aid in pinpointing the exact
center of the metal target. Only when the search coil
is directly over the center of the metal target (long-
est possible length PP Blocks) is the depth reading
giving you the most accurate depth indication. Also
of importance is that with some experience the
relative size and shape of the metal target can be
recognized during pinpointing.

Note: Dotted blocks for illustration purposes only.
Half block indicating MXT is not certain but possible.
Note: In this case, the 1¢ is the probable ID.
