Before getting Started
Before beginning an outside search,
you must test the unit with samples of
metal. Use the following:
an iron nail •
a five-cent coin (nickel) •
a one-cent penny (zinc coin, after •
1982)
a silver quarter •
Place the Metal Detector on a
wooden or plastic table with the
Search Coil face up. Make sure the
table is away from TVs, computers,
or any device that can cause
interference. See Figure 4.
note: Be sure to remove any
watches, rings, or other metal objects
on your fingers and hands.
Set Mode Switch to OPERATE and
VOLUME dial to mid-point. The
Metal Detector may sound a tone or
be silent. If not already done, adjust
the balance of the Metal Detector.
(See the “NOTE” under “Functions
And Indicators” on previous page.)
Once Detector is balanced, perform a
test of a sample to adjust the controls
to differentiate (“discriminate”)
between ferrous (iron) metals and
non-ferrous (metals.
To find ferrous metals (to 1.
“discriminate” iron), set the
DISCRIMINATION dial to MIN. See
Figure 5.
Hold the iron nail sample close to the 2.
Search Coil. The indicator on the
View Meter will swing to the left and
the “hum, hum” tone will be lighter.
Bring the other coins close to the 3.
Search Coil. The indicator will swing
to the right and the “hum, hum”
sound will become louder.
To find non-ferrous metals (such as 4.
nickel), set DISCRIMINATION dial to
midpoint setting. See Figure 6.
