We use sonde locating on jobs that require us to accurately pinpoint the location of non-metallic pipes and ducts. We send a small egg-shaped transmitter, attached to a fiberglass rod, through the pipe slowly while marking its precise location and depth. We can locate up to lengths of 300 feet.

This is also used to find where pipes and ducts are plugged so you don't have to dig up more than you have to, saving you time and money.
