Audio Features; Selecting Modes (Discrimination Patterns) - Garrett ACE 300i Owner's Manual

DIGITAL TARGET ID
Target ID can vary widely based upon the target's size
and thickness because small, thin pieces of metal cannot
conduct electrical current as well as thicker pieces of metal�
In addition, mineralized soils can cause Target ID errors,
especially for small targets�
Tip: Target ID is most reliable when the target is centered
under the searchcoil and the coil is swept flat and at a
constant height above the ground�

AUDIO FEATURES

Tone ID—The ACE 300i produces three distinct tones based
on a target's metal type and conductivity:
• High conductivity targets (Digital ID > 60) produce a
unique belltone signal�
• Medium to low conductivity targets (Digital ID of 40–60),
produce a medium-pitched signal�
• Ferrous targets (Digital ID < 40) produce a low-pitch
signal�
Headphone Jack—Use any headphones with a 1/4" plug�

SELECTING MODES (Discrimination Patterns)

Example: this is the preset notch discrimination pattern for COINS Mode�
Choose from one of four preset discrimination patterns or
use CUSTOM Mode to save a personal pattern�
Use the MODE buttons to scroll through the five modes:
• ZERO-DISC Mode–Detects every type of metal� All 12
discrimination pixels are switched on; no metals targets
have been notched out (eliminated)� Use this mode to find
all metal items or when the material of the desired object
is unknown� Switch to the Zero-Disc Mode to aid in locating
a target when its signal is inconsistent� Such signals could
mean a trash target is close to a good target�
• JEWELRY Mode–designed to find jewelry such as rings,
bracelets, watches, and necklaces, while ignoring most iron
trash�
• CUSTOM Mode–Can be programmed by the operator
and the ACE 300i will retain the changes when the detector
is switched off� The factory preset for the CUSTOM Mode is
the same as the COINS Mode� Begin with this discrimination
pattern and then use the DISCRIM and Accept/Reject buttons
controls to customize the mode�
