Sonde locating has been around for a long time. The idea is to energize the camera head so that you can find a specific location using an electromagnetic locator. The transmitter embedded in the camera head emits a radio frequency providing precise location and depth. This technique is used when you need to pinpoint the location that a drainline is damaged to help reduce excavation needed to make the repair.
Modern camera monitors are making the job even easier by providing “integrated line tracing” functionality. When a transmitter is hooked up to the monitor, the entire push cable can be energized.
