Classic® 5 ID
11
At the fully clockwise
setting nearly all trash
metals are rejected, as
well as some valu-
ables. Some larger
items, such as lead,
aluminum, pot metal
and tin will respond
regardless of the DISC
control setting.
An operator of the Classic 5 ID. may want to adjust the
DISC control for several reasons:
I. Minimum trash rejection is needed for detecting iron
and steel such as tools, horseshoes, relics and property
stakes. Iron and steels are rejected quickly as the DISC
control is turned clockwise.
II. For the rejection of most common trash metals and
the detection of most valuables the highest DISC
control setting that still responds to
nickel or a medium gold ring is ideal.
This should occur somewhere between
the RING RANGE “P” and the COIN
RANGE “P”.
III. For the rejection of all trash metals,
even though some valuables will also be
lost, the Coin Range and higher rejection
levels are useful. Some areas of severe
trash can easily be searched for silver/
copper coins at high DISC settings.
Nickel and small to medium gold items
will not be detected at high DISC
settings.
IV. The display indications perform
independent of the audio DISC control
setting. Metals rejected by the audio
discriminator will still indicate on the
display.
V. The idea of discrimination is to limit
the amount of trash metals you dig to a tolerable level.
Starting out at the Ring Range setting, if you’re digging
so much trash you’re not having fun, increase the DISC
control toward Coin Range slightly and try again. Find
the lowest level of discrimination that rejects the
common junk items in each particular area.

ALL METAL Toggle Control
The ALL METAL toggle located on the handle selects
between the two available operating modes. The
center DISC position is used during most searching
where the rejection of trash metals is desired. The
temporary (squeezed and held) or forward LOCK
positions are used to provide superior pinpointing,
and for searching when the desire is to detect all types
of metals, particularly iron/steel. The temporary
(squeezed and held) is the same as LOCK except it
provides for temporary use.
I. During most searching the center DISC position is
desired.
A. The DISC position allows the audio rejection of
trash metals based on the DISC control setting.
II. For pinpointing or when iron/steel items are
desired, squeeze and hold the toggle on the handle or
place it in the forward LOCK position.
A. When the ALL METAL toggle is in the temporary
or LOCK position the instrument responds to all types
of common metals.
Locked forward -
all metals for detecting iron,
steel, and all other metals
Center position -
discrimination for normal
searching with trash rejection
Temporarily squeezed -
all metals for pinpointing
