StructureScan Mini Series
 GSSI StructureScan Mini Series St. Louis Kansas CityIntroducing the Mini - our smallest StructureScan system. The StructureScan Mini Series is ideal for locating the position and depth of rebar, conduits, post-tension cables, and voids in the concrete. The high resolution, LED-backlit 5.7” display provides a detailed image of the subsurface structure. In addition to viewing, the data image can be stored directly to an SD-RAM card for later playback, or transferred to a computer for printing or integration into a report.

The StructureScan Mini Series offers a lightweight alternative to other GPR systems, weighing in at just over three pounds. The small size of the unit makes it easy to transport to the job site and once on-site, convenient to scan around obstacles and into tight spaces. The Mini is very easy to use – new users will become proficient in a few short hours. The Mini aids in target detection by marking the data on the screen with a small dot when characteristics of rebar or conduit are identified. The lasers on the side of the unit indicate the exact location of the center of the target for accurate marking of targets embedded in the concrete.

StructureScan Mini Deeper Signal Penetration
1600MHz GPR images St. Louis Kansas CityThe StructureScan Mini is Geophysical Survey Systems, Inc.'s (GSSI) portable integrated GPR system for concrete inspection.
