- Massive array of 40 antennas in two polarizations: A massive array of 40 antennas ensures a high sampling density. This results in accurate 3D modeling of the subsurface and ease of detecting buried targets and anomalies. The use of both polarizations provides optimal detection of main and junction pipes at the same time.
- Speed: Stream EM can be towed by a car up to 15 km/h (12mph). This boosts productivity as Stream EM can survey many miles per day, can be operated by 2 people, is able to run continuously without interrupting traffic and allows the crew to remain safe inside the vehicle.
- Accurate to less than 5 cm (2 inches): Stream EM can be interfaced with GPS or a total station in order to accurately geo-locate the surveyed area and to individually distinguish all the pipes, cables and anomalies detected with high accuracy.
- Professional Subsurface Utility Engineering (SUE) survey:Automatic transfer to CAD/GIS: Pipes, cables and buried object can be automatically transferred to CAD and GIS format with a proprietary software tool.
