PROSPECTING MODE
Coin & Treasure Mode is used for detecting
valuable objects, including old and modern coins,
jewellery and artifacts. Undesired objects such as
pull-tabs and bottle caps may be rejected. This mode
can be used in a variety of environments, such as
parks and salt water beaches.
The numerals (Target ID) and the segmented scale
(Pattern Discrimination Scale) are used to identify
particular metal objects in the ground.
Depth
The depth arrows indicate
the relative depth of a
target from the coil.
COIN & TREASURE MODE
Non-ferrous coin
Target ID
Metal objects are called
targets. The Target ID is
the numeric indication of a
particular metal object.
Pattern Discrimination Scale
Every detected target is represented
as a segment on the Pattern
Discrimination Scale. By turning on/off
individual segments, you are rejecting
or accepting target signals. A flashing
icon indicates a particular metal
detection.
Iron Mask (IM) Level
The numeric indication
of the Iron Mask Level
(not as the identifier of
particular targets as it is in
Coin & Treasure Mode).
Iron Mask Discrimination Scale
The visual indication of the Iron Mask
Discrimination Scale. By increasing the
Iron Mask Level you are rejecting more
iron signals. The Iron Mask range is 0-20
and uses only the first 20 segments of the
Discrimination Scale.
Prospecting Mode is used to find metal such as gold
nuggets and relics, in highly mineralised, ‘difficult’ areas.
Targets are identified by audio only, the number on the display
is not related to the target directly, but shows the value of
Iron Mask, as does the Discrimination Scale. In this mode, the
detector becomes more sensitive to small target signals.
The numerals (Iron Mask Level) and the segmented scale (Iron
Mask Discrimination Scale) are used to identify the amount of
iron signals being rejected by the detector.
A metal object in Coin &
Treasure Mode is identifi ed
by a single ‘beep’ tone
(Target Tones, pg. 38).
A metal object in Prospecting
Mode is identifi ed by an abrupt
change in pitch and volume
of the Threshold sound
(Threshold Tone, pg. 38).
Gold nuggets
The depth arrows
operate in Coin &
Treasure Mode only.
