Sonde Introduction

Sondes are small self-contained battery powered transmitters which are propelled through pipes
and ducts and can be located on the surface by a sonde locator or buried utility locator with a
sonde mode. Sondes are also built into other products such as a sewer camera, robotic crawler
camera, or attached to a jetter hose. Low frequency versions (512Hz/640Hz) can transmit through
some metallic pipes like cast iron pipes, which is why they are frequently used with sewer
inspection cameras.
Sondes come in a variety of sizes which ties into how deep they can be located. Different frequencies
are available which allow sondes to be located in metallic or non-metallic pipes and ducts.
A full range of Sondes are available to suit all applications:

  • Page 3 Method Insert the activated sonde into the pipeline. Push the sonde about 10 – 12 Feet (3-4m) into the pipe. Switch on the vLoc3 series receiver and use long presses on the “return key” until the sonde screen appears. Press the “f” key to select the sonde frequency being used. Hold the locator vertically and stationary with the tip on the ground.
  • Page 4 Keeping the null indicator on the vertical line, walk toward the arrow. A Sonde icon will soon appear. Keeping the locator vertical, carry on walking toward the Sonde until it is positioned on the cross hairs. The locator is now directly over the Sonde. The arrow will flip forward and back as the position is crossed.
