Dart Flexitrace 309-120 | 9mm x 120m Pipe Tracer System | Non-Metallic Utility Detection

The Dart Flexitrace 309-120 provides a specialized solution for the location of buried non-metallic pipes, ducts, and drains. This 120m system utilizes a high-tensile 9mm glass fibre rod with integrated copper conductors, allowing operators to energize the entire length of the rod or isolate the signal to the terminal sonde. Designed for efficiency, this unit can be deployed by a single person, offering a compact alternative to traditional sonde and cobra rod configurations.

How does the Flexitrace 309-120 locate non-metallic pipes?

The system operates in two modes: Line Location, where the signal generator is attached to one terminal and an earth stake to track the full rod path, or Sonde Location, which energizes the 12mm x 70mm end coil housing to pinpoint specific obstructions.

Can this system determine the depth of buried obstructions?

Yes, the Flexitrace system allows for precise depth determination up to 3 Mtr when used in conjunction with a compatible 33kHz Cable Avoiding Tool, though range varies by soil conditions and pipe construction.

What are the primary construction features of the 120m rod?

The rod is constructed from Glass Fibre with copper conductors protected by a durable polypropylene sheath, all mounted on a 950mm x 820mm x 400mm steel frame equipped with a manual safety brake.
