READING THE DISPLAY

1．Target Indicator
The LCD shows the probable type of the target, as well as the probable depth of the
target. The detector will register a repeating, unchanging target identification when a
buried target has been located and identified. If the search coil repeatedly 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 place with
repeatable signals out. Also, the greater the distance between the target and the coil, the
less accurate the target identification.
GOLD
- Gold objects will register on the left side of the LCD scale and will register
depending on its size. The smaller the gold object, the further to the left it will register.
Gold foil will register on the far-left side (same as Iron), Large gold items will register in
S-cap or Zinc.
IRON - Ferrous objects will register on the far-left side of the target scale. Objects in this
category could be worthless scrap, or more valuable iron relics.
5¢ - Nickel and new pull tabs will register here.
Pull-Tabs - Pull-tabs of older beverage cans will register here. Few new pull-tabs will
also register here. Many gold rings will also register here.
S-CAPS - Bottle caps with whorl and some small gold will register here.
1¢ - 1¢(post-1982) or copper coin registers here.
SILVER
10¢/1¢ - 1¢（pre-1982）, 10¢ or aluminum coin will register here .
25¢ - indicates the target may be 25¢, some small silver coins, or large aluminum coins
50¢ - target may be 50¢, or some large silver coins
Note: The target indications are visual references. Many other types of metal can fall in
any of these categories. The detector can indicate the presence of most common metal
objects. It is impossible to classify all buried objects accurately.
2．Depth Indicator
The Depth Indicator is accurate for coin-sized objects. It indicates the relative depth of
the target. Large and irregularly-shaped objects will yield less reliable depth readings.
When passing over an object, the depth indicator will light up and stay illuminated until
another object is scanned. Repeated indication at the same depth level indicates an
accurate target detector. 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
