CSI Pro™ 33
Tip for using Iron Audio:
In areas with high concentrations
of iron, it is recommended to switch off Iron Audio. Otherwise,
it may produce far too many signals. Then, if a target is
detected that has a questionable or inconsistent response,
switch on Iron Audio to check if it is iron.
To fully appreciate the additional information offered by
the Iron Audio feature, conduct the following experiment.
Start with the
CSI Pro
in Zero mode (IRON DISC setting at 00)
and pass the searchcoil over a bottle cap which is lying flat
on the ground. Note that the target response is consistent
with the audio of a good target and that the bottle cap's
flat surface gives a Digital Target ID reading generally in the
40–60 range.
Then, set IRON DISC to 35. With the Iron Audio feature
switched OFF, pass the bottle cap across the coil again.
Notice the subtle breaks and inconsistencies of the target
response, indicating it might be made of iron. Pass a non-
ferrous target such as a coin or gold ring across the coil and
note its clean tone in comparison to that of the bottle cap.
With IRON DISC remaining at 35, switch on the Iron Audio
feature. Pass the bottle cap completely across the coil again
and note the Low–High–Low response that is unmistakably
iron. Again, pass the non-ferrous target across the coil to
compare its audio to that of the bottle cap.
