We are now ready to discriminate targets from each other. We will
start with the DISCRIMINATE LEVEL at MIN. Please notice that the
DISCRIMINATE LEVEL knob has words that correspond to the items
that are discriminated out. While performing the Air Test, notice that your
DeLeón will continue to display target data for items that do not respond
with an audio signal.
All of your targets, except the small iron, will respond with a good
audio signal at the MIN setting. Next, we will turn the DISCRIMINATE
LEVEL up to the 5¢ setting. This level is high enough to knock out the
nickel. At this time the iron target and the nickel should give no response,
while most of the pull tabs, the zinc penny and the quarter will give a
solid response. The iron washer may fall out at some point or may give a
choppy signal all the way up to MAX. But reading the display should
give you the indication that it is odd-shaped iron. Next, turn the DIS-
CRIMINATE LEVEL knob just past the PULL TAB marking. At this
time most or all of the pull tabs should not give any audio signal. The zinc
penny and the quarter should give a strong signal. Now, roll the DIS-
CRIMINATE LEVEL all the way to MAX. Notice that the penny has
stopped responding and only the quarter is still responding. The discrim-
ination will not go high enough to lose most of the silver coins.
This Air Test was designed to quickly show you how your
Discriminate Mode works. Each machine may be a little different from
all others, so you may want to take some time and try different targets to
find the responses of your machine. At a later date, you may want to build
a test garden to test your detector in the field.
Adjust THRESHOLD
Flip the MODE switch to the center position. This will put your
DeLeón into the ALL METAL Mode. The display screen will show AM.
This is the indication that you are now in the ALL METAL Mode. The
ALL METAL Mode is used to pinpoint. The DeLeón uses a factory pre-
set ground balance in both the DISCRIMINATE and ALL METAL
Modes. This should work fine for most hunting conditions.
