To get experience with the sound of metal objects in
the ground, place a large nail, and/or a steel bottle
cap (not aluminum), a silver coin, and an item of
jewelry (mans gold ring preferred) on the ground.
Sweep the loop over these metals at a rate of three
to four seconds per pass. Note on the iron/steel the
inconsistency in the beep, and that it is a lower tone
and/or has a flutter to the sound. Note that typically
jewelry produces a medium tone beep and that it
provides a more consistent smooth sounding beep.
Note that the coin produces an even higher tone
beep and is also more consistent. An operator will
soon learn to ignore the lower tone flutter sounds
trash produces and listen for the smooth consistent
medium and higher tone beep that coins and other
valuable metals produce.
Once a smooth consistent medium to high tone
beep has been located, sweep the loop directly over
the center of the target several times and read the
possible I.D. on the L.E.D. display. Like the audio
discriminator, the display will tend to fluctuate on
trash, and read more consistent on valuable metals.
This is why we recommend relying on the audio
beep as the primary indication, and then check the
Display I.D.
The display will produce and hold indications as the
loop passes over ground, trash, and other metals.
Ignore the display until a consistent medium to high
tone beep has been located.
The more consistent the display, the more likely the
indication is correct. Trash metals tend to indicate
inconsistently.
Caution: two different types of metals lying near
each other in the ground may produce multiple
display indications that may appear to mimic trash.
Use the pinpoint “x” ing method to isolate the tar-
gets.
Operator Techniques
Pinpoint exactly where to dig by placing the TOG-
GLE in the All Metal position and “X-ing” the loop
slowly over the area “eyeballing” the center. The
detector will “beep” as the physical center as the
loop passes the center of the target.
As the loop nears the center of the target the sound
will increase in both tone and volume. The loudest
and highest tone beep indicates target center
(V.C.O.-Voltage Controlled Oscillator).
Note that some very slight loop movement is re-
quired. It is a good idea to place coins on the
ground and practice pinpointing. It takes some time
to develop pinpointing skills. Return the TOGGLE
to the DISC position prior to general searching.
For fast pinpointing the TOGGLEʼs Reset position
can be used. When pressed and held in Reset, the
All Metal mode is temporarily accessed for pin-
pointing. Once released the TOGGLE will auto-
matically return to DISC for searching.
If the desire is to detect iron/steel such as tools,
relics or property stakes, place the TOGGLE in All
Metal and leave it there during searching. Common
metals will respond with the same tone beep.
The L.E.D. display will continue to indicate I.D.
regardless of the toggle position.
Proper setting of the GROUND control is more
critical when searching in All Metal.
If searching near other metal detectors, rarely cross
talk or interference will result. However, if you
note some static chatter, simply increase the dis-
tance between you and the other metal detector.
