TARGET CONDUCTIVITY-
What i t does
This control allows the user to select whether to hear only low- conductive
targets, only high-conductive targets, or both types of targets. Low-con-
ductive targets, like small-to-medium sized gold nuggets will make a high-
tone sound. High-conductive targets like coins, except nickels, will make
a low-tone sound. This feature only works if the FINE Ground Balance

control is OFF, the Target Conductivity switch
must
be set to ALL or LOW
and all signals will sound the same.
