ULTRA-TRAC® APL Acoustic Pipe Locator

SENSIT ULTRA-TRAC APL Acoustic Pipe Locator

ULTRA-TRAC® APL is the perfect choice when it is necessary to accurately locate unmarked, underground piping systems. 


Acoustic Pipe Locator is ideal for finding 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. 


APL will significantly reduce the number of unlocatable pipes and identify potential cross bore risk locations when using HDD technologies.
