ACE 150 Features
The ACE 150 is designed with Garrett’s
exclusive Graphic Target ID technology, which
indicates the probable identification of a target
along a horizontal scale that reads from low
conductive metals (e.g. iron) on the left to high
conductive metals (e.g. U.S. coins) on the right.
10
Garrett Metal Detectors
1. Mode—Indicates which of the three detection
modes is selected by highlighting the corresponding
word on the LCD screen.
2. Target ID Legend—A printed 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
11
Ace 150 • Ace 250
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 absent (those Lower
Scale regions 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 actual 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 remain on. For best performance, replace the
old batteries with quality alkaline AA batteries.
NiMH rechargeable batteries may be used, but will
12

have a shorter life per charge. You can expect 20 to
40 hours of operation depending on battery type.
Access and replace the batteries on the ACE
150 and 250 by gently sliding the cover off the
control housing. Remove batteries from the ACE
when the unit will be stored for longer than 30
days.
8. Headphone Jack—Any 1/4” plug headphones
can be inserted into the jack found on the reverse
side of the Control Housing.
