Acoustic Pipe Locator

ULTRA-TRAC® APL is the perfect choice to accurately locate unmarked, underground piping systems. Acoustic Pipe Locator finds plastic pipe and systems with missing or broken tracer wire. Natural gas pipelines, water and sewer laterals are easily traced using state-of-the-art acoustic technology.

Combustible Gas Indicator Trak-It® IIIa
APL features an integrated tablet which allows the user to view scan data and 3D images of the surveyed underground area. The APL's on-board software now features improved gain correction to eliminate false-positives. See the 3D Pipe Mapping video to learn more.
