Service Locators

Non-invasive Electromagnetic locating equipment to find utility services.

What lies beneath? That is the question that is asked on all construction sites. Before any construction or excavation commences a DBYD certified locator is required to perform a site investigation to reduce the risk of underground service strikes and disruption to public utility assets.

ULS pride themselves in being at the forefront in underground service locating. The quality of our services is known to be the highest in the industry.

Our fully trained staff have a combined 25 years’ experience in the underground service location industry.

All underground service locations are carried out in accordance with AS5488-2013 Classification of Subsurface Utility Information.

IDS Opera Duo

The Opera Duo is designed to allow ULS Locators making detection of buried utilities easier through its new software interface while needing virtually no maintenance for lifetime of equipment. The unit is based on a dual frequency antennae of 250MHz & 700MHz; The 250MHz frequency is for scanning and providing high resolution images of deep targets while the 700MHz is for scanning and providing high resolution images of shallow targets. The Opera Duo therefore provides the ability to locate the exact position of pipes and cables by a single scan (instead of changing antennae) – Saving time & increasing productivity.

VM-880 Ferrous Metal Detector

The VM-880 is the latest generation of the ever popular 880 ferrous metal locator. Enhancing existing features and adding new, it incorporates the following to enable fast location of buried or hidden assets.


S13 Sonde

The S13 Super Small Sonde is designed to be used for tracing the paths of non-metallic pipes, ducts, sewers and drains, and in the precise location of blockages and collapses.

The S13 sonde transmits a locate frequency at 33kHz, making it compatible with most Radiodetection Cable and Pipe locators, including the RD8100 Precision Locator range and the C.A.T4 Cable Avoidance Tool range.

Our ULS DBYD Certified locators will arrive onsite and utilise the use of EMF and GPR Technology to locate all underground services as per scope of works outlined by the client.

Once onsite, your ULS locator will use the latest technology in DBYD Plan collaboration along with our advanced technology and state of the art equipment to provide a more accurate result than our competitors.

We provide expert advice to our clients to ensure the protection of underground assets which reduces the risk of potential strikes onsite.

All ULS locators are highly trained in the use of their equipment and complete works in accordance with AS5488-2013 “Classification of Subsurface Utility Information”.


ULS have made a substantial investment not only in equipment, but also in training for its operators, with competencies in cable location; confined space entry; resuscitation; trenching and underground electrical awareness; construction site access; traffic control; road sign placement; environmental awareness; oil spill awareness; noxious weed control; sediment control; rail track safety (NSW and QLD); and metered standpipe.
