Tilted Sondes - RIDGID NaviTrack Scout Operating Instructions Manual

5.7 Tilted sondes

If the sonde is tilted, one Pole will move closer to the sonde
and the other farther away so that the sonde location no
longer lies midway between the two poles. The signal strength
of the nearer Pole becomes much higher than that of the more
distant Pole. In the extreme, as the sonde tilts to vertical, the
one Pole moves to a point directly above the sonde and this
Pole will also correspond to the point of maximum signal
strength. The other Pole will not be seen. Therefore even if the
sonde is vertical, as it could be if it fell into a break in the line
or an underground tank, the sonde can still be located.
What is seen on the screen is a Pole of maximum signal
strength when the sonde is vertical.

The multi directional antennas allow the depth to be measured
even if the sonde is tilted. In this circumstance the force depth
feature must be used to take a depth measurement (see
Measuring Depth).
