About Sondes

Benefits of a Frequency Locator

512 Hz sondes, also referred to as “moles” or “beacons”, work with any Schonstedt pipe & cable locator.  Sondes benefit a variety of industry applications. In water & sewer, they can help pin-point blockages or pipeline defects when used with video inspection systems. You can trace a path and determine the depth of a non-metal pipe such as HDPE, PVC, transcite or clay tile. In cable applications they can be used to trace empty fiber-duct or adjacent conduit runs and stop at unmarked underground vaults or splice boxes. The depth accuracy of a sonde’s position can help reduce excavation costs and time. Depending on frequency, a self-contained battery powered sonde can be detected as deep as 16ft.
