18COIN & TREASURE MODE 
PROSPECTING MODE 1919
Coin & Treasure Mode is used for detecting valuable objects, including old and modern coins, jewellery and artifacts. Undesired objects such as
The numerals (Target ID) and the segmented scale (Pattern Discrimination Scale) are used to identify particular metal objects in the ground.
Target ID
Metal objects are called targets. The Target ID is the numeric indication of a particular metal object.
Pattern Discrimination Scale
A metal object in Coin & Treasure Mode is identified by a single ‘beep’ tone (Target Tones, pg. 38).
Depth
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.
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
A metal object in Prospecting Mode is identified by an abrupt change in pitch and volume of the Threshold sound (Threshold Tone, pg. 38).
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.
The depth arrows indicate the relative depth of a target from the coil.
The depth arrows operate in Coin & Treasure Mode only.
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
