Depth Reading - Kayoba 002-163 Operating Instructions Manual

EN
Low tone level
Caps, 5-cent coins and the smallest gold
objects generate low tones (low frequency
signal).
Medium high tone level
Can rings, screw caps, zinc coins, newer penny
coins (after 1982) and gold objects generate
medium high tones (medium frequency signal).
High tone level
Coins with the values 1 cent (1950), 10 cent,
25 cent and 50 cent fall in this category (high
frequency signal).
USING IN THE FIELD
Reading the display
Target reading
The display shows the probable character
of the target metal and the probable
target depth. When a buried object has
been localised and identified the detector's
identification is repetitive and unchanging.
If the target identification is not repeated
consistently when the search coil is moved over
the area then the target probably consists of
scrap metal or oxidised metal. With practice
the user learns to only dig when the signal is
repeated. The identification also becomes less
reliable as the distance between the target and
the search coil increases.
Gold
Gold objects are indicated on the left side of
the display. How gold objects are indicated
depends on their size. The smaller the object
is, the further to the left they are shown. Small
gold objects are indicated on the far left side
54
(under iron objects), large gold objects under
S-caps or Zn.
Iron
Objects containing iron are shown on the far
left on the display. Objects in this category can
be scrap metal or more valuable iron relics.
• 5¢: 5-cent coins and most newer can rings
(those that stick to the can) are indicated
here.
• Can rings: Can rings from older canned
drinks are indicated here. Some newer
can rings and many gold rings are
indicated here. S-CAPS Screw caps and
some smaller gold objects are indicated
here.
• 1¢: 1-cent coins (after 1982) and copper
coins are indicated here.
Silver
• 10¢/1¢: 1-cent coins (before 1982), 10-cent
coins and aluminium coins are indicated
here.
• 25¢: 25-cent coins, some silver coins and
larger aluminium coins are indicated here.
• 50¢: 50-cent coins and some larger silver
coins are indicated here.
The target indications serve as guidance. Many
other types of metal can be indicated in the
different categories. The metal detector can
eliminate or indicate the presence of most
common objects of scrap metal, but cannot
reliably classify all buried objects.

DEPTH READING

The depth reading is reliable for coin sized
objects. The relative depth of the target is
indicated. The depth reading is less reliable for
large and/or irregularly shaped objects. The
depth reading is activated when the search coil
is moved over an object and remains activated
until some other object is indicated. Repetitive
