When you go over a large, shallow target, the
CZ-70 Pro will respond with a distinctive bell tone.
This is because metal detectors can only identify
small targets. What usually happens is the
detector circuits overload and identify a large
target as "good" (silver, coin, etc.). Your CZ-70
Pro, however, will alert you to a target that's big
and shallow and cannot be accurately
identified. (Big deep targets, however, will
usually be classified as a coin. Also be aware that
large coins on the surface may set off the bell
tone. And the optional, smaller 5-inch coil is more
likely to overload than the standard 8-inch coil.)

Now, using the NOTCH and Arrow touch pads,
reject the IRON category by removing the
marker from below the IRON icon. You will find
that the CZ-70 Pro rejects small iron targets and
no longer responds either with an audio tone or
a display identification.
