GND BAL
— Ground Balance
Control Knob
Rotate GND BAL to change
the detector’s internal Ground
Balance Setting.
By calibrating the detector to
the actual Ground Phase of
the soil you are searching, you
will cancel out signals from the
earth’s naturally occurring
minerals, thereby improving your ability to detect buried metal objects.
The default ground setting is 82.
The knob has no minimum or maximum set point; it rotates
continuously without a stop.
The faster you turn the knob, the more quickly the ground setting
changes. To make small changes to the ground setting, move the
knob slowly, one click at a time.
There are over 1,000 different ground balance settings, but only 100
different numbers are displayed on the screen, as 2-digit numbers
from 00 to 99. The displayed setting will change by one number for
roughly 10 clicks of the knob.
See section on Ground Balancing for a detailed description.
GAIN
The gain control increases, or multiplies, the signal from a buried metal
object.
Rotate the GAIN knob clockwise in order to increase the size of signals
generated. For maximum
detection of the smallest or
most deeply buried objects,
increase the gain. To minimize
the weakest signals, set the
gain at a low level.
There are 20 gain settings. 5 is
the lowest; 99 is the highest.

AUDIO TARGET IDENTIFICATION SYSTEM
Different types of metals will induce different types of sounds,
depending on your TONES setting.
There are 4 choices in DISCRIMINATION MODE
:
dd11..
Medium-to-high pitch tone, varying in proportion to
target signal strength. Large shallow objects will
produce a squeal. The variable audio pitch provides
you more information about the detected object.
Volume and Pitch increase with increase in signal
strength.
dd22..
Iron produces a low-pitch tone regardless signal
strength. Volume varies in proportion to signal
strength. Non-ferrous targets respond as in d1.
dd33..
Three different audio tones.
Low Tone: Iron
High Tone: Foil, 5¢, Tab and Zinc
Very High Tone: Dime, 25¢, and 50+
dd44..
Four Different audio tones
Low Tone: Iron
Medium Tone: Foil, Tab, and Zinc
High Tone: 5¢
Very High Tone: Dime, 25¢ and 50+
The default setting is d2.
To choose from the above selections, press the TONES touch pad.
Each press of the TONES touch pad cycles to the next selection.
There are 4 choices in ALL-METALS MODE
A1, A2, A3, A4 - pitch varies with each setting.
