87Understanding your X-TERRA - Final Words
In All Metal, those deep iron targets are more likely to bounce between the most
conductive reading of +48 and the most ferrous reading of -8. Having a specic notch
segment established to accept the most ferrous property values (-8) results in less
TID bouncing (-8 to +48 ) on deep iron targets. X-TERRA users will nd that the higher
frequency coils produce more “wrap around” signals than lower frequency coils. This is
due to the fact that the higher frequency coils expand the TID range for low conductive
targets, but compress the TID range of higher conductive targets. Since the highest
notch segment of the X-TERRA 505, 70 and 705 is “tighter” (by design) than the other
notch segments, you can greatly reduce the eects of deeply buried iron by rejecting
the +48 notch segment.
Reason two...
When you turn the X-TERRA on, all the settings you used the last time you hunted are
saved, with one exception. It will not turn back on to All Metal. It always sets up in the
last Discrimination Pattern you used. So, in order to not have to worry about forgetting
to switch to All Metal, I established one of my Discrimination Patterns to accept all
notches. This way, when I turn on the detector, it sets up in a Discrimination Pattern with
zero discrimination.
