Local Underground Penetrating Radar & Locators in Hornsby Heights NSW

Common questions about underground penetrating radars

We’ve collected some frequently asked questions about pipe and cable locators to help you in making your decision:

• Is ground penetrating radar (GPR) safe? Although the name may sound like a hazardous technique, it is extremely safe and emits less energy than a cell phone.
• How deep can an underground locating service scan? The depth of GPR depends on the material being surveyed, the frequency used and the materials in between. For example, clays are difficult to penetrate, whereas sandy soils can allow detection for up to 9 metres.
• Can underground service locators find gold? They technically do work, however metal detectors are usually more suitable.
• How do underground utility locating services work? Services generally use GPR, which sends a tiny pulse of energy via an antenna. A computer then records the time and strength of any reflected signal. Pipes, cables and other man-made objects will show on the radargram, which can be interpreted.
