Sierra Super Trac Owner’s Guide
2. Blocks-
A series of 16 blacks 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 from a sepa-
rate source than the VDI numbers. A second opinion
a full block indicates the ST has complete informa-
tion for target identification. A half block indicates the
ST has partial information. A quarter block indicates
the ST has only a small amount of target information.
3. Labels-
The most common metal target (or
targets in some cases) within a particular Block is
listed on the display and referenced on the label
below the display. If two targets are listed, the first
to be listed is the most common, the second is 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 indicat-
ing in descending order (as the target gets closer to
the bottom of the search coil) the indicator provides
an aid in better locating the target in the ground (how
deep you will need to dig) and whether the metal
target is likely worth digging. Only the heavier more
valued targets get deeper into undisturbed ground.
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. When the search
coil is directly over the center of the metal target (lon-
gest possible length PP Blocks) the depth reading is
giving you the most accurate depth indication. With
some experience the relative size and shape of the
metal target can be recognized during pinpointing.

Note-
In this case, the 1¢ is the probable ID.
Half block indicates target I.D. is not certain.
