Headphone Jack —Any headphones with a 1/4” plug can be
inserted into the jack at the rear of the Control Housing.
AUDIO FEATURES
Tone ID —The Tone ID feature produces three distinct audible
tones based on a target’s metal type and conductivity:
• High conductivity targets (such as silver) produce a
unique belltone signal.
• Medium to low conductivity targets (such as jewelry or
small gold), produce a medium-pitched audio signal.
• Ferrous targets (such as iron and nails) produce
a low-pitch audio signal.
