UtilityScan® HS is GSSI’s newest GPR system designed specifically for the utility locating industry. It incorporates the 350 HS antenna, a state-of-the-art digital antenna designed with our patented HyperStacking technology.

The HyperStacking technology is the foundation of this system, providing the user superior high resolution data, better depth performance, and RF noise immunity compared to traditional GPR antennas.

Typical Uses for UtilityScan DF Include:

  • Utility detection – metallic and non-metallic
  • Environmental assessment
  • Damage prevention
  • Geological investigation
  • Archaeology
  • Forensics

Dedicated System

  • The UtilityScan HS is specially designed for shallow subsurface investigations. The easy-to-use, user selectable text or icon based interface allows for quick set-up and efficient surveys. Paired with our 4-wheeled rugged cart, the UtilityScan HS is ready to withstand the job site’s toughest conditions.

Enhanced Antenna Performance

  • The 350 HS is a state-of-the-art digital antenna using our patented HyperStacking technology and works seamlessly with our customized Panasonic G1 control unit.

First-Class Data Visualization

  • The UtilityScan HS makes it easy to customize the data display with advanced display modes, including 3D visualization, advanced signal floor tracking, and the newly released LineTrac is also available.

Data illustrates several metallic and non-metallic utilities at varying depths.

New Accessory for UtilityScan Systems

GSSI is pleased to announce LineTrac™, an accessory to our UtilityScan systems employing either the DF or HS antennas. LineTrac adds the ability to detect AC power and induced RF energy present in buried utilities.

Locating specific pipes and cables in large underground networks can be very complex. Ground conditions resulting from varying soil conditions can make the job more difficult and time consuming when relying on any one detection method. GSSI recognizes that ground penetrating radar (GPR) is not the only tool for the job and has developed an accessory that combines GPR data with a radio detection sensor.

The most important requirements for utility locators are ease-of-use, accuracy and reliability. The combination of UtilityScan and LineTrac addresses these needs with features that deliver accurate, dependable and repeatable performance.

LineTrac employs a three-axis 50/60 Hz magnetometer that is used to locate powered and non-powered utilities. LineTrac detects extremely low amplitude AC signals associated with difficult to locate utilities.


LineTrac includes a number of features to easily identify target utilities, including:

  • Easy integration with GSSI UtilityScan systems with digital antennas
  • Seamless data fusion with GPR data
  • Aids in target discrimination
  • Designed to work with existing radio detection transmitters
  • User selectable Frequency Mode or Power Mode options
  • 20 Hz to 50 KHz active frequency bandwidth
  • Rugged, IP-65 rated enclosure

Compatible Systems

  • UtilityScan Pro - with DF or HS antenna
  • UtilityScan DF
  • UtilityScan HS
