ACE 150 Controls

1. POWER Pushbutton - Press the POWER button once
to turn the detector ON or OFF. Note: After turning
detector off, wait 3 to 5 seconds before turning back ON.

2. SENSITIVITY Pushbutton - Push the SENSITIVITY
button to step through the four (4) sensitivity levels,
which are continuously shown on the LCD screen.

Use lower sensitivity levels in locations where the
detector is behaving erratically due to excessive metallic
trash interference, high mineral soils, saltwater beaches,
or other metal detectors are present.

3. MODE Pushbutton - Push the MODE button to select

one of three desired detection Modes:

• All-Metal Mode - This MODE is designed to
detect every type of metal and should be used
when you want to find all metal items or when
the materials of the desired object is
unknown.

Switch to the All-Metal Mode to aid in locating a
target when its signal is inconsistent.
(Inconsistent signals can mean a trash target is
nearby a good target).

Use higher sensitivity levels when searching for very
small or very deep targets.
