TARGET INFORMATION
Target ID Cursor
(Upper Scale)
Target ID Legend Discrimination
Pattern (Lower Scale)
Target ID Legend—Works in conjunction with the Target ID
Cursor to indicate a target's probable identity. Ferrous (iron)
targets will indicate on the left half, non-ferrous targets that
are thin or have low conductivity will indicate in the middle,
and thick or high conductivity targets (e.g. thick copper) will
indicate at the right.
Target ID Cursor (Upper Scale)—The Target ID cursor, in
conjunction with the Target ID Legend, indicates the probable
identity of a detected target. The upper scale consists of
twenty (20) graphic segments for Target ID.
Lower Scale—The lower scale, or Notch Discrimination
Scale, continually indicates the discrimination pattern. The
CSI Pro will produce an audible target response for the pixels
that are switched on, and no audible response for those
that have been switched off. The Target ID Cursor will always
indicate all targets.
Depth Indicator—The depth of a .38 caliber bullet, or
similar sized target, is indicated in 2" (5cm) increments. Note:
targets larger than a .38 caliber bullet may display shallower
than actual depth while targets smaller than a .38 caliber
bullet may display deeper than actual depth.

DIGITAL TARGET ID
Digital
Target
ID
The CSI Pro’s Digital Target ID system provides a specific
target value to help identify targets more precisely. Targets
are identified on the LCD by number, with items near 1 being
the most ferrous. The most conductive targets (such as large
copper items) register closer to to 99.
The Digital Target ID is a more precise version of the
Target ID Cursor shown in the Upper Scale. Each Target ID
Cursor has a width of 5 digital points. For example, a Digital
Target ID of 47 will light the cursor from 45 to 50.
This system, when used in conjunction with the audio
target signals, provides you with more information. The
sample chart on the following page provides Digital Target ID
ranges of some commonly found items.
It is important to note that detection depth can exceed
Target ID depth (i.e. faint targets at depth can be heard
without providing any Target ID).
The Digital Target ID for conductive metals such as lead,
brass or copper can vary widely based upon its size and
thickness. This is because small, thin pieces of metal cannot
conduct electrical current as well as thicker pieces of metal.
Therefore, tiny lead bullets—for example—will register lower
on the Target ID scale than would a larger, thicker piece of
lead, even if the two pieces have identical purity. In addition,
in mineralized soils, the Target ID of small metal objects can

Note: Target values can vary based on the orientation of the target in the
ground, amount of ground mineralization, etc. It is important to practice in
the field to learn how these factors can affect Target ID. This chart indicates a
range of values in which certain targets are more commonly found. The Target
IDs of U.S. coins are also included for reference.

DIGITAL TARGET ID
be skewed by the ground mineralization into numeric IDs that
normally indicate iron. Most lead projectiles indicate in the 35
to 60 range. Very tiny lead pellets and deeply buried targets
with small signal response may not give a numeric reading at
all. Nevertheless, targets which do not give any Target ID are
often worth investigating.
Tips: Digital Target ID is most reliable when the target is
properly pinpointed and centered under the searchcoil and the
coil is swept flat and at a constant height above the ground.
Use a magnet to help remove small bits of shallow iron and
then scan over the area again to see if the Target ID has
changed.

SENSITIVITY
SENSITIVITY
Pushbutton
Sensitivity
Indicator
The CSI Pro has eight (8) settings for sensitivity. Use the
(+) or (-) SENSITIVITY buttons to step through the eight levels,
which are continuously shown on the LCD.
Use higher sensitivity levels when searching for very small
or very deep targets. Use lower sensitivity levels in locations
where the detector is behaving erratically (due to excessive
metallic trash, highly mineralized soils, electrical interference
or the presence of other metal detectors) and the erratic
operation cannot be resolved with discrimination, ground
balance, or by changing frequency.

GROUND BALANCE
GND BAL

NOTCH DISC
Pushbuttons
(use with GND BAL)
GND BAL
Indicator
(only displays on
LCD when in use)
GND BAL Setting
(only displays
while in Ground
Balance mode)
GND BAL Pushbutton—Hold for Automatic Ground Balance
or use in conjunction with the NOTCH DISC pushbuttons for
Manual Ground Balance. The Ground Balance setting will be
retained when the detector is switched OFF.
As ground mineralization begins to increase, it has a
negative affect on detector performance. The greater the
amount of mineralization, the greater the loss of detection
depth and Target ID accuracy. It is imperative to ground
balance the detector to maintain optimal performance.
The CSI Pro can be ground balanced either automatically
or manually to cancel unwanted ground signals and obtain
maximum stability and target detection. By calibrating the
CSI Pro's ground balance to the phase (measurement) of

CSI Pro™ 17
the ground's signal, the result is deeper target detection, more
accurate Target ID, and more stable operation.
Note: Always locate an area of soil free of metal before
attempting to ground balance the detector.
Automatic Ground Balance—Press and hold the GND BAL
pushbutton while continually "bouncing" or "pumping" the
searchcoil from 1 to 8 inches (2 to 20 cm) above the ground.
When there is a minimal audio response from the ground,
release the pushbutton and begin hunting. The ground balance
value will have been indicated in the center of the LCD. Low
ground balance values indicate conductive soil; high ground
balance values indicate ferrous soil.
Note: If the CSI Pro's Ground Balance setting does not change
during the auto ground balancing process, the detector is either
sufficiently ground balanced already or the current ground
exhibits such neutral mineralization that the settings will not
change.
Manual Ground Balance—Press and release the GND BAL
pushbutton and continually bounce (pump) the searchcoil from
1 to 8 inches (2 to 20 cm) above the ground. If low tones are
produced, increase the Ground Balance setting using the (+)
NOTCH DISC pushbutton. If high tones are produced, decrease
the setting using the (-) NOTCH DISC pushbutton. Press and
release the (+) or (-) NOTCH DISC pushbuttons to make single-
step adjustments, or press and hold to make large adjustments.
Continue bouncing the coil and making adjustments until a
minimum audio response is obtained, indicating the detector is
ground balanced. The Ground Balance setting will be indicated
on the LCD. Press and release the GND BAL pushbutton again to
exit Manual Ground Balance mode.

You may want to use the Manual Ground Balance function
to ground balance slightly positive to enhance detection of
small targets or balance slightly negative to reduce detection
of "hot rocks," terra cotta, clay bricks and saltwater.
Typical Ground Balance Ranges:
80–99: Highly ferrous (magnetite, ferrous oxide minerals,
black sands, hot rocks, terra cotta)
60–80: Moderately mineralized soils (red clay, brown clay,
iron-bearing clay minerals, etc.)
20–60: Likely an iron object
0–20: Highly conductive, non-ferrous minerals such as
saltwater

FREQUENCY ADJUSTMENT
SENSITIVITY
Pushbutton
PINPOINT/
Freq Adjust
Pushbutton
Use the PINPOINT/Freq Adj pushbutton in conjunction with
the (+) or (-) SENSITIVITY pushbuttons to adjust frequency.
The CSI Pro is capable of operating at four slightly different
frequencies in order to minimize the interference caused by
electrical sources (e.g. power lines) or other metal detectors.
To see current frequency setting, hold down the PINPOINT
button and press the (+) or (-) SENSITIVITY pushbuttons. Tap
one of the SENSITIVITY pushbuttons again to change the
frequency to find one with the least amount of interference.
The frequency setting (F1–F4) will be indicated on the LCD.
Release the PINPOINT button when finished.
Note: Frequency adjustments are small and therefore do
not affect target detection capabilities.
