vScan Sonde Locating Quick Guide V1.1
Sonde Introduction
Sondes are small self-contained battery powered transmitters that 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 frequen-
cies are available which allow sondes to be located in metallic or non-metallic pipes and ducts.
The vScan receiver has sonde frequencies of 33kHz, 512Hz and 640Hz.
