SENSITIVITY Pushbutton

Use the (+) or (-) SENSITIVITY buttons to step through the
eight (8) sensitivity levels, which are continuously shown on
the LCD screen.
Use higher sensitivity levels when searching for very
small or very deep targets. Use lower sensitivity levels in
locations where the detector is behaving erratically due to
excessive metallic trash, highly mineralized soils, saltwater
beaches, electrical interference or the presence of other
metal detectors.

SELECTING MODES (Discrimination Patterns)
The ACE 350 includes five Modes. Select the mode that
best suits the targets you hope to find or use the CUSTOM
Mode to create your own personal settings. In each mode,
minor changes in the preset discrimination patterns have
been programmed to optimize hunting for such typical
target(s).
This does not mean that the detector will search only for
jewelry while in JEWELRY Mode. It simply indicates that the
discrimination pattern is optimized for locating most jewelry
items. The JEWELRY Mode will still locate coins, relics and
other non-jewelry items.
• JEwELRY Mode
The discrimination pattern for this mode is designed
to find jewelry such as rings, bracelets, watches and
necklaces. Three pixels of ferrous targets have been
excluded to ignore most nails and small iron pieces.
Some iron pixels remain in order to minimize target
masking effects (see page 23 for more on target
masking).
The LCD screen in JEWELRY Mode will appear as:
In JEWELRY Mode, the lower 3 pixels are notched out.
