SeeSnake® LT1000

To turn the SeeSnake Sonde ON while using the LT1000,

press the Sonde Key . A Sonde icon will appear on

the display while the Sonde is ON. The display may also

show some lines of interference from the Sonde’s trans-

mission. These will vanish when the Sonde is turned

OFF by again pressing the Sonde Key .
The most workable approach to tracking the Sonde is

to run the pushrod into the pipe about five or ten feet /

1,5 to 3 meters and use the locator to find the Sonde’s

position. If desired, you can then extend the pushrod

a similar distance further down-pipe and locate the

Sonde again starting from the previous located posi-

tion. To locate the Sonde, turn the locator ON and set

it to Sonde mode. Scan in the direction of the Sonde’s

probable location until the locator detects the Sonde.

Once you have detected the Sonde, use the locator in-

dications to zero in on its location precisely. For detailed

instructions on Sonde locating, consult the Operator’s

Manual for the locator model you are using.

Line Tracing The SeeSnake Pushrod

The LT1000 also enables you to trace the line of the

pushrod underground, using a standard RIDGID loca-

tor such as the NaviTrack® II, the Scout™, the SR-20 or

the SR-60. To line-trace the SeeSnake pushrod, simply

connect a line transmitter with one connector well-

grounded to the grounding stake and the other con-

nector clipped to the Transmitter Clip-on Terminal. The

Transmitter Clip-on Terminal is a metal lug located just

under the left end of the keyboard area as shown in Fig-

ure 27.

Set the line transmitter and the locator to the same fre-

quency, such as 33kHz and use the locator to trace the

line (Figure 28). The camera’s built-in 512Hz Sonde may

be on at the same time, and if your locator is equipped

with SimulTrace™ dual-frequency capability, you can

follow the pushrod all the way to the camera’s location

and then detect the Sonde in the camera as you ap-

proach it above ground.
If you don’t have the SimulTrace™ feature, use a line

transmitter and a locator to line-trace the pushrod.

When the signal fades, switch the locator to Sonde

mode at the frequency of the in-line Sonde, usually

512Hz. Pick the signal up from where the line-trace

frequency started to weaken and zero in on the in-line

Sonde. Because locating frequencies from transmitters

can cause distortion of the image on the monitor, it is

best to turn Sonde and line transmitters OFF while in-

specting the interior of a line and turn them ON only

when ready to do a locate.
