Locating Sondes with Schonstedt

A sonde is a small battery-operated beacon that can be placed inside PVC pipe for easy tracing. Schonstedt pipe locators allow you to detect the signal from a sonde and use it to determine the location of underground piping. These dependably accurate readings go a long way toward decreasing risk and inspiring confidence throughout the construction process.

Principles of Magnetic Locating

Magnetic pipe and cable locators work due to the magnetic fields present under the Earth’s surface. Metallic objects below the Earth’s surface are impacted by magnetic fields and can therefore be detected using magnetic locators. Schonstedt locators can detect the presence of a metallic object when there is a difference in the attraction of the two magnetic fields on the unit. The locator informs the user that a metallic object is present with a high-pitched sound and a visual display.

Utility Locator Infographic

These underground utility location tools are designed to withstand the rigors of tough daily field use and a wide range of environmental conditions. We are factory-authorized dealers and represent multiple underground location equipment brands. We carry Schonstedt Utility Locators, PipeHorn Utility Locators, Leica Pipe and Cable Location Tools, and Rigid SeekTech Water Pipe and Cable Location Equipment. Keep in mind that locating underground utilities requires a well-trained and experienced operator, as well as reliable equipment. If you have questions about selecting underground utility location tools and location equipment, please feel free to contact us.

TIP: The basic premise behind an underground utility locator is that it works by producing and transmitting a signal onto a utility that is metallic that the receiver can detect. A signal (measured in kHz or Hz) can be produced by a transmitter and is sent through the utility by either conductive or inductive means. "Conductive" means a direct connect connection such as alligator clips. "Inductive" means the signal is "induced" onto the metallic utility line with an induction clamp which is secured or clamped around the utility line but does not connect metal to metal as the conductive alligator clip does. Inductive is great when you don't have access or ability to do a direct connection. In case you're wondering, the conductive method is better since it is metal to metal and the transmitter is able to send a signal better. Once your transmitter is connected and turned on producing a signal on the utility, you can then take the receiver part of the instrument and wave it over the areas you believe the utility to be in. When you start picking up the signal you will over time learn how to pin-point exactly where the utility line is buried, and how deep. This takes practice over time but new-comers to the utility location profession can learn it fairly quickly but should be trained by someone with years of experience. We have trained and knowledgeable staff waiting to help you with questions with any of the Pipe Locators, Cable Locators, Pipe Location Tools, and Best Pipe and Cable Locators that we sell.
