Once the
l
ine
has been located, the depth can then be found. Refer to the figure below for a
reference. Start by moving the
r
eceiver
along the path behind the
s
onde
with the antenna in line
with the
s
onde
and find a NULL between the PEAK ghost signals. Mark this point
(A)
. Then move
the
r
eceiver
along the path in front of the
s
onde
and find another NULL. Mark this point
(B)
. Next,
measure the distance between these two points. The depth of the pipe is 0.7 times the distance
between the two points.
