TARGET ACCEPTANCE
The drawing illustrates what types of targets can be
accepted and rejected in the two ranges. Synchro-
nized audio signals indicate the section in which tar-
gets have been detected:
Ferrous Reject: Audio threshold is maintained. No
change in sound.
Ferrous Accept: Normal increase of sound indicates
acceptable target.
Non-ferrous Reject: Audio threshold is maintained,
or there might be a slight decrease in the sound level
which indicated an unacceptable target.
Non-Ferrous Accept: Clear and distinct acceptance
tone.
More on Target Audio
When a metallic object is accepted, the detector’s
speaker or headphone sound will increase from your
audio threshold level. Some rejected targets, how-
ever, may cause the audio to “break up” or sound
erratic.
This is generally a response to shallow trash targets
and can be remedied by raising the height of your
searchcoil when scanning. Another indication of a
reject target is an audio signal as you scan one way
and no response when scanning from the other di-
rection.
Test typical trash items before hunting with the CX
to determine what signal your detector will give on
encountering them.
