has the following three search audio modes:
• All-Metal
• Discrimination
• Mixed-Mode
All-Metal mode produces audio only from the all-metal
channel, and Discrimination mode produces audio only from
the discrimination channel. Mixed-mode produces both the all-
metal audio and discrimination audio. The audio can be sent to
a standard speaker, a pair of plug-in headphones, or wireless
headphones.
Note that the various settings apply only to one or the other
processing channels (audio modes). It’s important to remember
which settings affect which mode, and that’s not difficult once
you understand what the settings do.
All-Metal Audio
The all-metal channel simply detects and indicates metal
targets. It does not care what those targets are, nor does it
attempt to tell you what they are. The all-metal audio channel is
also used during pinpointing.
