TARGET IDENTIFICATION
Target-ID
When metal objects are detected, the detector will emit a sound, a Target-ID
Category icon will illuminate and a 2-digit Target-ID number will appear on the
screen. Possible Target-ID numbers range from 1 to 99. This number
represents the electrical conductivity of the target; higher numbers indicate
more highly conductive targets.
Target indicators on the screen only represent the last object detected. This
detector has fast target response and is able to detect different objects in very
close proximity. Therefore, the Target-ID displayed may change rapidly as you
sweep the searchcoil.
Three seconds after a target is detected, the ID numbers will time-out and
disappear and the Target Category Icon will change to the non-illuminated state.
Iron, Gold and Silver Indicators:
The group border momentarily flashes
when an object in that group is present.
The border flashes independently of the notch settings.
Relic hunters will frequently seek out iron-laden sites as good prospective
treasure-hunting sites. The iron indicator alerts the user to the presence of
iron, even if iron has been discriminated out. Relic hunters can search free of
iron-target audio, yet still be alerted to the presence of ferrous objects or
search with no discrimination and use the FeTone™ feature to decrease the
Audio Volume of ferrous targets.
4-Tone Target Identification
The detector will provide 1 of 4 sounds
for any metal object detected: a bass,
low, medium or high tone. This audio
feedback system is useful in
conjunction with the visual Category
Icon system described above.
Ferrous, gold and silver targets will generally register within their
corresponding category icon ranges. Targets that are not gold or silver register
within the same range according to their electrical conductivity. Note that the
electrical conductivity of a target depends on both its composition and size.
Silver is more conductive than gold so it registers farther to the right; and the
larger the silver object, the farther it registers to the right. There are a wide
variety of metals and no target can be identified for certain until unearthed.
See coin reference table on page 17.
