Utility Scanner

The ESS Utility Scanner has been designed to find even the deepest targets while still providing high-resolution. The unit boasts the most diverse sensor suite on the market today. This versatile unit can be used to locate utility lines underground vaults, power lines, pipes, voids, and geologic horizons.  Advanced software to generated maps, 3D subsurface images, and reports.

Dual frequency GPR antennas produce high-resolution scans without sacrificing penetration depth. The 750 MHz antennas sense objects to approximately 10 feet depth, while the 350 MHz antennas detect objects as deep as 20 feet.

All cables have been eliminated to increase reliability.  WiFi link between scanner and table computer insures trouble free operation.

An optional RTK GPS system provides precise positioning without laying out a survey grid.  This greatly reduces survey time and increases productivity.

The entire system (scanner, tablet computer, RTK GPS, tripod, and battery chargers pack neatly into one rugger shipping case.
