Line Locating with a SeeSnake Inspection System

This article describes how to locate the path of a pipe by line tracing the push cable inside the pipe using a SeeSnake® camera reel and monitor. This is especially useful for inspecting non-metallic or non-conductive pipes.

Line trace the push cable by using a transmitter to induce current onto the push cable. For best results, use frequencies 33 kHz and higher. The signal can be traced by utility locating receivers such as the RIDGID® SeekTech® SR-20, SR-24, SR-60, NaviTrack® II, or Scout.


  1. Insert the transmitter’s ground stake into the ground and clip one of the transmitter’s leads to it.
  2. Clip the other lead to the transmitter clip-on terminal on the back of the monitor.
  3. Power on the transmitter and receiver and set both to the same frequency. The transmitter may cause interference and can affect image quality.
  4. Trace the line.

For additional instructions on line tracing, refer to the manuals for the transmitter and receiver models you are using.
