It may take some time and experience to utilize the Target ID feature in your search area
because Target IDs as well as the depths the IDs are generated by different brands and
models of detectors are also different.
As mentioned before, ID Masking is the ability of the device to ignore (not produce a
warning tone or ID) unwanted targets. ID Masking is not active in the General Search
mode. ID Masking values of the discrimination modes are preset by the factory. If you want,
you can change the ID Masking values in the menu.
To change the ID Masking value, first choose the ID Masking option in the menu and using
the + or - switches, either increase or decrease it to the number you have determined.
Please keep in mind that certain metals, other than the ones you are masking, will also be
lost or their signal strength will diminish resulting in loss of depth.
For example; when you set the ID Masking to 40, the device will ignore all signals with IDs
less than 40 and will not produce a warning tone. The device will also miss targets under
rocks of which the received IDs are less than 40.
To give another example, in the case of receiving multiple IDs - let's say 35 and 55 - due to
target orientation or metal property, if you mask the IDs up to 40, 35 will fall in the masked
range so the signal strength may diminish and depth may decrease.
IMPORTANT!
In general objects such as knives or pocketknives, guns and manhole covers
all contain iron. Therefore, you should be careful when using the ID Masking feature. As the
ID Masking value increases, the device's detection depth for these objects will decrease.
