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 signiﬁ cance to

how these blocks appear. A full block indicates the

MXT 300 is conﬁ dent of indication. A half block in-

dicates the MXT 300 is not conﬁ dent but is making

an educated indication. A quarter block indicates the

MXT 300 is not conﬁ dent at all, guessing based on

what little information the target is producing.

3. 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 ﬁ rst to be listed is the most

common and the second listed slightly less common

than the ﬁ rst.

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 (lon-

gest possible length PP Blocks) is the depth reading

giving you the most accurate depth indication. Also

of importance is that with some experience the rela-

tive size and shape of the metal target can be recog-

nized during pinpointing.

Note: Dotted blocks for illustration purposes only.

Half block indicating MXT 300 is not certain but possible.

Note: In this case, the 1¢ is the probable ID.
