to the fact that metal detectors can only identify
small targets. What usually happens is that the
detector circuits will overload and identify a large
target as “good” (silver, coin, etc.). Your CZ-5,
however, will alert you to the fact that the target
is big and shallow and can not 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. The
optional, smaller 5 inch coil is more likely to
overload than the standard 8 inch coil.
10. You may also note that some rectangular tabs ID
as round tabs and vice versa. Because of the wide
variety of sizes, shapes and conductivity of the
many pull tabs manufactured over the years, there
is overlap as far as identification goes. Small pieces
of tabs or aluminum are often misidentified. The tail
of a round tab for example, may ID as a nickel.
