• The second Pole will be a similar distance from the
Sonde location in the opposite direction. Locate it in the
same manner and mark it with a red triangular marker.
• If the Sonde is level, the three markers should be
aligned and the red Pole markers should be similar dis-
tances from the yellow Sonde marker. If they are not,
a tilted Sonde may be indicated. (See "Tilted Sonde"
on page 20.) It is generally true that the Sonde will be
on the line between the two Poles, unless there is
extreme distortion present.
Step 3: Verify the locate
• It is important to verify the Sonde's location by cross-
checking the receiver's information and maximizing
Signal Strength. Move the SR-20 away from the max-
imum Signal Strength, to make sure that the signal
drops off on all sides. Make sure to move the unit far
enough to see a significant signal drop in each direc-
tion.

• Double-check the two Pole locations.
• Notice that the Measured Depth reading at the maxi-
mum Signal Strength location is reasonable and con-
sistent. If it seems far too deep or too shallow, recheck
that there is an actual maximum Signal Strength at that
location.
