Proceq GPR Solo: Powerful sensors with radar beams for every application. Intelligent software at your fingertips. Important note: GP Solo is designed for organizations that prefer to use their own cloud infrastructure, including government agencies, ministries, and military operations. The mission behind Proceq GPR is simple: to look into concrete deeply and clearly, to detect objects effortlessly and reliably, and to collaborate anywhere, anytime, for hit prevention, as-built verification, and structural investigation. The lightweight, rugged Proceq GP8000, Proceq GP8100 and Proceq GP8800 sensors are the world's first and only handheld GPR devices with Stepped-Frequency Continuous-Wave technology. The true-ultrawideband antennas and Swiss-made, optimized electronics deliver unparalleled resolution and penetration depth—at the same time. The magic starts once you connect a Proceq GPR sensor wireless to your iPad and fire up the Proceq GPR Solo 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 from your iPad with colleagues anywhere, anytime, and export your measurements files to other GP Solo users, or snapshots & into the SEGY formats for post-processing and reporting. 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. The Proceq GPR Solo product family enables both quick spot-checking and deep imaging of concrete structures, including shallow utility locating (Proceq GP8000 and Proceq GP8100 only). And that is why it is the perfect complement to Pundit Ultrasonic PD8050 and Profometer PM8000 & PM8500 by Screening Eagle Technologies.
