Instruction manual

39
Again, the number of tones you set for your X-TERRA is simply a matter
of personal preference. If you chose single tone, all targets will provide
an audio report at 450 Hz. Regardless of whether you chose two tones,
three tones or four tones, targets with a negative TID (ferrous targets) will
produce an audio report of 130 Hz. With the exception of the single tone
setting, once you get into the positive side of the notch segments, the
pitch of the audio response will increase as the conductivity value of the
target increases.
The tone assigned to each target value will vary by the model of your
detector, due to each model having a dierent number of notch
segments. Therefore, check your Instruction Manual for the specics of
your detector. On a side note... although Minelab display the multiple
tones as 99, there aren’t 99 tones. There is actually one tone for each
notch segment, as shown in the chart on page 38.
