Pulser™

What is Pulser™?

High-Resolution Subsurface Imaging—Without Drilling

Pulser™ delivers the depth of resistivity surveys with near ground-penetrating radar (GPR) vertical resolution, providing detailed subsurface insight to 350 feet below ground surface with resolution as fine as two feet—all through a nonintrusive, mobile survey system.

Pulser™ is a next-generation geophysical system designed for accurate subsurface geologic analysis without excavation or drilling. By integrating resistivity-based depth penetration with enhanced vertical resolution, Pulser™ bridges the gap between traditional resistivity methods and standard GPR.

The system is used to identify geologic traps, define mitigation pathways, and map shallow geology with exceptional clarity. Leveraging existing ground-truth data, Pulser™ eliminates the need for invasive stratigraphic drilling and replaces it with a fast, efficient, and noninvasive data collection process. Its mobility and precision make it ideal for environmental, geotechnical, and engineering applications where speed, accuracy, and minimal site disturbance are essential.

Pulser™ is a fast, nonintrusive system for mapping the three-dimensional distribution of lithologic and stratigraphic units to depths of up to 350 feet below ground surface. This proprietary hybrid technology combines resistivity and ground-penetrating radar (GPR) components to generate high-resolution subsurface reflection patterns.

These reflections identify lithologic boundaries based on changes in mineral composition, porosity, and pore-filling materials such as air, water, or contaminants. The data are calibrated to existing geologic databases and integrated into a comprehensive geologic, geotechnical, and subsurface conceptual site model to support remediation design.

Portable and compact, Pulser™ requires only about five minutes of setup per station, operates on nearly any surface, and does not interfere with site operations. By defining subsurface conditions before drilling, Pulser™ enables more targeted, cost-effective boring and recovery programs.
