The magic starts once you connect a Proceq GPR sensor wireless to your iPad and fire up the Proceq GPR Live app. The lightning-fast user interface increases your productivity by making measurements and analysis a breeze with intuitive gestures and controls; for example, by switching between real-time radargram and migrated views on the fly. A rich feature set brings advanced workflows on-site, so that you can get more things done while in the field. Broaden your measurements with geolocation, tags, photos, voice memos and comments in the Logbook. Enrich the raw data, migrated, superline and time slice views with your annotations. Access and share them with colleagues anywhere, anytime, and export your measurements into the URL, SEGY, WORD, EXCEL and HTML formats for post-processsing and reporting, thanks to the Screening Eagle Workspace. Detect the presence of alternating current with the built-in Live Wire kit (Proceq GP8000 and Proceq GP8100 only). Instantly reconfigure the wireless wheel and the antenna polarization without tools or screws (Proceq GP8800 only). Look deep into concrete on-site with Time-Slice View and 3D View, and superimpose these views onto the structure with robust, accurate Augmented Reality—an industry first. Building on these advanced visualization capabilities, AI-powered features further boost productivity. AI Autotagging automatically detects and tags most objects in the scan and generates Excel-ready reports with object positions, depths, and distances, dramatically reducing manual interpretation and accelerating reporting The Proceq GPR Live product family enables both quick spot-checking and deep imaging of concrete structures, including shallow utility locating (Proceq GP8000 and Proceq GP8100 only).
