side to side and front to back at the lowest constant height
to locate the area causing the loudest signal. Watch the bar
graphs on the LCD Screen to also see the peak signal area.
With practice at pinpointing, you will be able to pinpoint
objects very quickly.
4. Five MODE options
—Like the
ACE 150
, the
ACE 250
has
All-Metal, Jewelry and Coins modes. The
ACE 250
, however,
has two additional modes: Custom and Relics.
• CUSTOM Mode
—This Mode can be programmed by
the operator. The
ACE 250
is factory preset with the
CUSTOM Mode set the same as the COINS Mode. By using
the DISCRIM and ELIM pushbuttons, an operator can
modify the Notch Discrimination settings to individual
specifications, which will be retained in the CUSTOM Mode
when the
ACE
is turned OFF.
The CUSTOM Mode can be used to find specific metal
items. For example, if an earring has been lost, scan the
matching earring with the
ACE 250
while in the CUSTOM
Mode. Note where the Target ID cursor appears when the
earring is scanned. Next, use the DISCRIM pushbutton to
move the Target ID cursor to the left and right. Push
the ELIM button to delete the LCD cursors on the notch
Discrimination Scale
(see illustrations)
, leaving only the
one where the Target ID cursor illuminated when the
earring was scanned. Depending upon how the earring is
laying in the ground, your ability to find it will be enhanced
by turning on an additional cursor on either side of the
target cursor. The
ACE 250
is now programmed to find only
the missing earring based on the conductivity of its
matching pair.
ELIM can also be used to modify the Notch Discrimination
Scale to reject a specific type of trash while detecting all
other metal. When a trash metal is audibly detected while
hunting, simply push the ELIM button to create a notch
where the Target ID cursor signaled the presence of the
trash. The next time the
ACE 250
encounters the same
trash item, it will not produce an audible signal.
• RELICS Mode
—Designed to eliminate trash targets
normally associated with relic hunting, while detecting
good targets in the lower conductivity range, such as lead
and brass.
Use the ELIM pushbutton to delete LCD cursors on the Lower Scale.
