As mentioned before, Target ID is a 2-digit number produced by the detector and it gives
you an idea about what the target may be. The number is displayed both on the LCD panel
and the numeric display on the handle.
Under certain conditions, the device may generate multiple IDs for the same target. There
may be a few reasons for this: target orientation, target depth, purity of metal, corrosion,
ground mineralization etc. Based on these factors, even the sweep direction may cause the
device to generate multiple IDs.
On the other hand, the device may not give any ID under some circumstances. For the
device to generate an ID, the target signal must be strong enough for signal processing.
Therefore, although it may detect very deep or small targets, it may not be able to generate
an ID.
What you should keep in mind is that the target IDs are estimated values and there is no
way of knowing for sure what’s buried other than to dig it up.
Non-ferrous metals such as copper, aluminum, lead etc. have high IDs. The ID range of
gold, however, is broad and can fall in the same range with some trash metals such as iron,
folio, screw caps, and pull-tabs. Therefore, if you are looking for gold targets, digging out
some trash metals is expectable.
Probable IDs and ranges of some targets are shown in the table below:
At the maximum level of iMASK, false signals will disappear or will be minimized. However,
in some cases, increasing the iMASK will result in loss of depth for certain metals such as
copper.
NOTE:
iMask value ranges between 0-6. The factory default is 3. At ''0'', the iMASK feature
will be inactive. If the ground is not highly mineralized or does not contain many hot rocks,
setting the iMASK to ''0'' is recommended.
