Signal Response
7.1 Typical Signal Responses
The metal handles on
the septic tank cover
will provide a usable
signal to determine the
location of the actual
cover (Fig. 8).
Large metal objects
may cause double
signals as indicated
(Fig. 9).
The center of the
cover is found by
sweeping the ≠locator
back and forth to
create a ring pattern
≠response. The center
null will designate the
cover’s center.
The joints, elbows and
ends of iron pipes will
create the strongest
≠signals (Fig. 10). Hold
the locator in a vertical
≠position while
searching to produce
the best results.
