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.
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 screen. 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
screen, but with the same metallic
signature. Also, the greater the
distance between the target and the
coil, the less accurate the target
identification.
GGOOLLDD TTAARRGGEETTSS
Gold objects will
register on the left side of the LCD
scale. Gold is categorized depending
on its size. The smaller the gold object,
the further to the left it will register.
SSmmaallll ggoolldd iitteemmss
will register under
Fe or Foil.
MMeeddiiuumm--ssiizzeedd ggoolldd iitteemmss
will usually
register under 5¢ or Tab.
LLaarrggee ggoolldd iitteemmss
will usually
register under Tab or Zinc.
SSIILLVVEERR TTAARRGGEETTSS::
Silver objects will
normally register to the right of the
scale, under Dime, Quarter, or 50+,
depending on the size of the object.
The larger the object, the farther to
the right it will register.
IIRROONN::
Fe is the scientific designation
for Iron. Most iron objects will fall into
the Fe category. Very large iron
objects like a manhole cover will
usually fall into the 50+ category.
55¢¢::
Nickels and most newer pull-tabs
will register here.
TTAABB::
Older pull-tabs and ring-pulls
from beverage cans usually will
register here. Many gold rings will also
register here.
ZZIINNCC//11¢¢::
Newer pennies (post-1982)
will register here. Many non-U.S. coins
will also register here.
Screw caps from glass bottles will
register here. Large gold rings, like a
class ring, could also register here.

Upon the 1st press of NOTCH, a “
--
” will flash over the “Fe” symbol.
Each subsequent press will move the flashing “
--
” to the right.
The following target categories can be notched in or out:
Fe, Foil, 5¢, Tab, Zinc, 50+
After the 50+ category, pressing NOTCH will exit the NOTCH function.
To select a category for notching, press NOTCH until the flashing “
--
”
appears over that category’s icon. After a few seconds, the flashing “
--
”
will time out and the current target category will be notched.
Practice pressing NOTCH a few times and its function will become obvious.
The NOTCH feature is not available in Auto Tune Mode.
FREQUENCY
Use this control if detector behaves erratically
and you suspect electromagnetic
interference from some other electronic
device. The control will change the detector’s
operating frequency. Press until you find one
of the frequencies which minimizes the
interference.
Choices are:
1 – default frequency
2 – 1st alternate frequency
3 – 2nd alternate frequency
Changing frequency may require you to change the ground balance
setting. See section on ground balancing.
PINPOINT
This touchpad, in the middle of the panel,
activates the PINPOINT mode.
Press-and-Hold this touchpad for static
detection.
Volume and pitch increase with increase in
signal strength.
Target DEPTH, in inches, will be indicated in
the middle of the display.
The depth indicator is calibrated to coin-sized
objects. Objects other than coins will indicate
relative depth readings.
DDIIMMEE::
Dimes and pre-1982 copper
pennies will register here.
CCaauuttiioonn::
The target indications are
visual references. Many other types of
metal can fall under any one of these
categories. While the F5 will eliminate
or indicate the presence of most
common trash items, it is impossible to
accurately classify ALL buried objects.
