and become more sensitive to small targets.

Take some time to try waving targets in front of the coil with differ-

ent sensitivity settings. Notice that the higher the sensitivity setting, the
farther away from the coil that a target can be and still respond with an
audio signal.

Perform Air Test in DISC Mode

The Discriminate Mode is used to filter unwanted targets from good

targets. The principle behind this is pretty simple. The detector sends out
a signal and then receives it back creating a small electronic field. As
metal passes through the field that the detector generates, it causes a
change in the received signal. The amount of change that each type of
metal causes is fairly constant; therefore, we can tune our detectors to
miss targets that we don't want to find. The change is based on the
amount of conductivity of each target type. The general list of conductive
targets is as follows: iron, foil, nickels, gold jewelry, pull tabs, screw tabs,
pennies and silver coins starting with dimes and working up to silver dol-
lars. This is very easy to visualize using the bar graph. This list is meant
to be a guide only. There is a point that some pull tabs, nickels and gold
jewelry overlap. Also, the depth of the target and its orientation in the
ground can change the received signal. A coin that is flat to the coil will
produce a better signal than a coin that is on edge. Take some time to try
different combinations of depths and orientation of your targets and find
out how your detector responds.
