2. Target ID Legend - A Target ID Legend is located
directly above the LCD screen and indicates commonly
found targets and metals. When a target is detected, the
Target ID cursor will appear below the word that most
likely indicates the type of target found, based on its
conductivity.
3. Upper Scale - The Upper Scale, where the Target ID
cursor is illuminated when a target is detected, consists
of five (5) graphical segments.
4. Target ID Cursor - The Target ID cursor is illuminated
in the Upper Scale and indicates the probable identity of
a detected target.
5. Lower Scale - The lower horizontal scale, or Notch
Discrimination Scale, indicates the discrimination pattern
where the ACE will or will not produce an audible signal
when a target is located. This scale changes when
switching between Detection Modes.

No audible signal will be produced when a target is
located where a notch is present (those regions of the
Lower Scale where no cursors are visible).
6. Coin Depth - The depth of a coin, or similar sized
target, will be shown on the LCD screen. Depth is
indicated when the LCD scale is illuminated at 2", 4" or
6+ inches. Sweep over the target with the searchcoil 1"
from the soil to get the most accurate reading. Note:
Targets larger than a coin may display shallower than
acutal depth while targets smaller than a coin may
display deeper than actual depth.
7. Low Battery Indicator - When the unit's batteries
become weak, the Low Battery Indicator will turn on. For
best performance, replace the old batteries with quality
alkaline AA batteries. NiMH rechargeable batteries may
be used, but will have a shorter life per charge. You can
expect 20 to 40 hours of operation depending on battery
type.
