Using headphones (not supplied) improves
battery life, and prevents the sounds from
annoying bystanders.
It also allows you to hear subtle changes in the

4-TONE AUDIO SYSTEM
While the LCD (Liquid Crystal Display) is very accurate in identifying
buried objects, the user in the field does not always maintain the
display screen in his field of vision. Therefore, we have incorporated an
audio feedback mechanism to alert the user to the nature of buried
objects. This audio feedback system first alerts the user to the presence
and classification of objects, whose nature and location can be
confirmed using the LCD display.
The 4-tone audio target identification system functions only in the motion
modes of operation. The detector must be in the DISCRIMINATION
mode, as indicated on the display. In PINPOINT mode, the detector will
emit only a monotone sound.
The detector can sound four different tones, depending on the object
detected.

DEPTH AND TARGET DISPLAY
READING THE DISPLAY
The Liquid Crystal Display (LCD) shows
the PROBABLE identification of the
targeted metal, as well as the PROBABLE
depth of the target, in inches.
An arrow will illuminate under the
target category where an object is
best classified, and stay illuminated
until another target is identified.
The detector will normally register a
repeating, unchanging target
identification when a buried target
has been located and identified. If,
upon repeated passes over the same
spot, the target identification reads
inconsistently, the target is probably a
trash item, oxidized metal, or too
deep to be classified accurately. With
practice, you will learn to unearth
only the more repeatable signals.
The segment identifications are highly
accurate, when detecting the objects
described on the label. However, if
you register in a given category for an
unknown buried object, you could be
detecting a metallic object other than
the object described on the label, but
with the same metallic signature. Also,
the greater the distance between the
target and the coil, the less accurate
the target identification.

DEPTH INDICATOR: (in pinpoint mode)
The Depth Indicator is calibrated to
coin-sized objects. It indicates the
depth of the target, in inches. Large

yield less reliable depth readings
When passing over an object, the depth
indicator will light up and stay
illuminated while an object is in the field
of detection. the depth indicates the
distance, in inches from the center of
the search coil to the target.
2 DIGIT TARGET INDICATOR
The 2-digit target indicator, in the middle
of the LCD display, provides a specific
target value to help identify buried
targets more accurately. With practice in
the field, you will learn to associate target
values with the probable identification of
buried objects. The target value can vary
each time the coil passes over the
target, depending upon the angle of the
object and the distance from the coil.
The table below lists some common approximate target value equivalents. With

SENSITIVITY ADJUSTMENT
ELECTROMAGNETIC INTERFERENCE
Use the Sensitivity Control is to eliminate
Electromagnetic Interference (EMI).
The F2 metal detector is an extremely sensitive
device; the search coil creates its own
magnetic field and acts like an antenna. If
your detector beeps erratically when the
search coil is motionless, the unit is probably
detecting another electromagnetic field.
Common sources of EMI are electric power lines, both suspended and buried,
motors, and household appliances like computers and microwave ovens.
Some indoor electronic devices, such as dimmer switches used on household
lighting, produce severe EMI and can cause the detector to beep erratically.
Other metal detectors also produce their own electromagnetic fields; so if
detecting with a friend, keep two metal detectors at least 20 feet apart.
If the detector beeps erratically,
SSeennssiittiivviitty
In most urban environments, you should be able to search without chatter from
interference at the default sensitivity setting (default setting is the sensitivity level
at power-up, 4 bars), or at one level reduced from default. At maximum
sensitivity, the F2 will “chatter” in proximity to underground or overhead power
lines, or to indoor or outdoor electrical devices. In fact, if you notice rapid
chatter with the searchcoil near the ground, you may be able to trace the
approximate location of the underground power lines by following the chatter.
To manage chatter, which is most likely from electrical interference:

SEVERE GROUND CONDITIONS
A secondary use for the Sensitivity Control is to reduce false detection signals
caused by severe ground conditions. While the detector contains circuitry to
eliminate the signals caused by most naturally occurring ground minerals, 100%
of all ground conditions cannot be anticipated. Highly magnetic soils found in
mountainous and gold-prospecting locations can cause the detector to emit
tones when metal objects are not present. High saline content soils and sands
can sometimes cause the detector to beep when no metal target is present.
If the detector emits false, non-repeatable, signals, REDUCE THE SENSITIVITY.
