ground mineralization, the higher the sensitivity
loss. For example, you may be able to detect a
penny 6 inches deep at zero discrimination, but
no deeper than 4 inches at the pull tab
discrimination point. Also, ground mineralization
can reduce a detector’s ability to discriminate
accurately. In highly mineralized soil, some trash
targets may not be rejected.
6. If a target gives a good strong response in the
search mode but no response in the Zero-Motion
Pinpoint mode, you may have “tuned-out” your
target (and all others) by pulling the TRIGGER-
SWITCH over another piece of metal. If you
suspect this may be the case, check the ground
first in DISC 1 at zero discrimination to insure
there’s no buried metal before placing your coil
on the ground and pulling the TRIGGER-SWITCH to
go into the pinpoint mode.
7. In trashy areas, to reduce the “masking”
effects of trash on nearby good targets, use a
shorter and slower sweep pattern. Also, the
optional smaller 5-inch search coils will zero in on
good targets closer to trash.
8. When in doubt about the possible identity of a
target, dig it up.
9. The 1266-X is an easy detector to use but if
you’re having trouble with any aspect of its
operation (pinpointing, searching, false signals,
etc.) go back and reread the part of this manual
relating to your problem.
