Ground Balancing (continued)
that when the searchcoil is lowered to the ground in PinPoint, Stat or Motion All Metal Mode,
the sound will get louder as the searchcoil approaches the ground. The sound will grow
quieter as the searchcoil is raised. What, if anything, you will hear in Discrimination Mode
depends on the Discrimination setting.
When searching in an All Metal Mode, if ground balance is properly set to cancel the ground,
and you sweep over a positive hot rock, the rock will give a “zip” sound similar to that of a
metal object.
NEGATIVE RESPONSE
If the GB setting is too low a number, the response of minerals will be negative. When the
searchcoil is lowered to the ground in PinPoint, Stat or Motion All Metal Mode, the machine
will be silent. The machine will sound off as the searchcoil is lifted away from the ground.
What, if anything, you hear in Discrimination Mode depends on the Discrimination setting.
When searching in Motion All Metal Mode, a negative hot rock will produce a “boing” sound
after passing over it, making it difficult to know where it is located. It will not have the sound
and “feel” of a metal object.

LCD Visual Display (continued)
Most gold jewelry is small, and will tend to read in the 16-55 range. Silver jewelry usually has
more metal in it and therefore tends to produce higher readings.
Since different metal objects can produce similar signals, and since minerals in the soil can
distort the signals, the probable Target ID's are just that -- probable. There is no way of
knowing for sure what's buried other than to dig it up.
DEPTH
When the trigger is pulled to facilitate pinpointing an object, the 2-digit numerical display
indicates the approximate depth of the object, in inches, based on the assumption that the
object is a typical U.S. coin. Small objects will read deeper than they actually are, and large
objects will usually read shallower than they actually are.
The DEPTH bar graph on the left of the display divides target depth into shallow, medium and
deep. This depth range appears while searching, and is less accurate than the value derived
using the pinpoint toggle switch.
Bar graph ranges for a coin-sized object are Shallow (0-4inches), Medium (4-8 inches) and
Deep (8).
CONF (Target Confidence Indicator)
This 6-segment graphic indicates how confident the detector is of the 2-digit target
identification it has assigned. If all 6 segments are displayed, you can be confident that the
