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.
The detector will register a consistent target
identification, upon each sweep of the coil,
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, or oxidized metal. With practice, you will
learn to unearth only the repeatable signals.
The segment identifications are highly
accurate, when detecting the objects
described on the label. However, if an object
registers 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.
GOLD TARGETS Gold objects will register on
the left side of the LCD scale.
Gold flakes will register under iron.
Small gold items will register under foil or 5¢.
Medium-sized gold items will register
between nickel and or alum.
Large gold items will register under Zinc.
SILVER TARGETS: Silver objects will register
to the right of the scale, under dime or higher.
IRON: All sizes of iron objects will register on
the far-left side of the scale. This could indicate
a worthless item such as a nail, or a more
valuable historic iron relic.
FOIL:
Aluminum foil, such as a gum wrapper,
will register as foil. A small broken piece of pull
tab may also register here.
5¢: Most newer pull-tabs from beverage cans,
the type intended to stay attached to the can,
will register here. Many gold rings will also
register here.
ALUM: Older pull tabs, which always detached
completely from the can, register here. Many
medium size gold ring also register here.
ZINC: Newer US pennies (post-1982), and
Canadian $1 and $2 coins register here. Many non-
US coins of recent vintage will also register here.
DIME: Dimes and older copper pennies (pre-
1982) register here.
50¢+: Silver Dollars, Half-Dollars and Quarters,
very large iron objects, like a sewer lid, will
register here.
Caution: The target indications are visual
references. Many other types of metal can fall
under any one of these categories. While the
detector will eliminate or indicate the presence of
most common trash items, it is impossible to
accurately classify ALL buried objects.
5-SEGMENT DEPTH INDICATOR:
The Depth Indicator is accurate for coin-sized
objects. It indicates the depth of the target, in
inches as follows:
Segments Illuminated
Top Segment = 0 to 2” deep.
Top 2 Segments = 2” to 3” deep.
Top 3 Segments = 4” to 5” deep.
Top 4 Segments = 6” to 7” deep.
All Segments = 8”+ deep.
Large and irregularly-shaped objects will yield
less reliable depth readings
When passing over an object, the indicators
will light up and stay illuminated for three
seconds. If the depth indication varies with
each sweep, try sweeping at different angles;
there may be more than one target present.
With practice, you will learn the difference
between accurate readings, multiple targets,
and highly erratic readings which evidence
trash or irregularly shaped objects.
