RIDGID NaviTrack Scout Operating Instructions Manual page 9

Warning! – Be sure that the frequency selected matches the
desired use. 512 and 33 are available as a sonde AND a line
trace frequency. Using a sonde frequency for line tracing or
vice versa, can cause the Scout to display incorrect depth
information.
.
Go to the suspected sonde location. If the direction of
the pipe is unknown, push the sonde a shorter distance
into the line (~5m from the access, is a good starting
point).
5.4.2 Next, use one of the following methods to locate
the sonde:
Method 1 – Maximize Signal Strength
1. Hold the Scout so the mast is out away from your body.
Sweep the mast in the suspected direction of the sonde
while observing the signal strength and listening to the
sound. The signal will be highest when the mast is
pointing to the sonde.
2. Lower Scout to its normal operating position (mast verti-
cal) and walk in the direction of the sonde. As you
approach, the signal strength will increase and the
audio tone will ramp and rise in pitch. Use the signal
strength and the sound to maximize the signal.
3. Once the maximum has been found, place the Scout
close to the ground over the peak and move in all direc-
tions to make sure that the signal drops off.
Note – The highest signal counts, the equator line can be on a
different position than the highest signal if the sonde is tilted
(see section tilted sonde).
Method 2 – Follow the Equator – Then Maximize
1. Works best in unobstructed, open areas, when the
sonde is expected to be horizontal. Sweep the mast
and then walk in the direction of maximum signal
strength as in Method 1.
2. When the Scout displays a steady Equator line cen-
tered on the screen, follow it towards increasing signal
strength. When maximum signal strength is reached
move the Scout along the Equator and in all directions
to be sure that it is on the peak.
When the Sonde is tilted be sure the find the maximum signal
as that is the place where the sonde will be.
Verify the locate.
1. At the point of maximum signal strength, and with the
mast vertical, move the Scout perpendicular to the
Equator line on the screen. When the Pole icon
appears move Scout until the Pole icon is centered on
the crosshairs with the lower antenna ball on the
ground. Place one of the triangle orange markers on
the ground at this spot.
View when Scout is on the pole.
2. Move Scout back across the Equator line to the other
pole. Center the crosshairs on the second Pole icon
and mark its position as before.
