Proceq GPR Live: Powerful sensors with radar beams for every application. Intelligent software at your fingertips. 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 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). And that is why it is the perfect complement to Pundit Ultrasonic PD8050 and Profometer PM8000 & PM8500 by Screening Eagle Technologies.

Digitize Reality: Transform your mobile device into a powerful 3D scanner. Simply point and record to create professional-grade 3D models. Pair with a compatible RTK device for centimeter-level accuracy, precise measurements, and geolocated 3D reconstructions. Visualize the captured model in the app, upload and export, and view it in AR. New ArcGIS Workflow: PIX4Dcatch now streams ArcGIS data in realtime in AR to provide in-field operators full contextual information about the entire site including 3D reconstructions and attributes. Our capture feature generates complete and defensible georeferenced 3D reconstructions which can be communicated seamlessly back to ArcGIS. New Guide-To Feature: PIX4Dcatch has a guide-to feature directing users to specified geolocated assets for staking, boosting onsite efficiency and accuracy. Just select the point or reconstruction you would like to find and follow the arrows in AR. WORKFLOW 1 – Scan & Capture Walk around your site. The app automatically gathers data and provides live feedback using iOS LiDAR, ensuring you capture every detail. For enhanced accuracy, use an RTK device compatible with PIX4Dcatch, PIX4D Autotags with a fully automated workflow, or combine both. 2 – Process, Analyze & Share Process your data by uploading to PIX4Dcloud for online analysis and sharing, or export to PIX4Dmatic for desktop processing. Both platforms offer a 14-day free trial. Projects can also be exported to third-party photogrammetry software. Measure spaces, document results, and enjoy all the benefits of a detailed 2D/3D model of your surroundings. 3 – View in AR Experience an immersive augmented-reality view. Display 3D models and points directly in your phone camera in AR. ____________________ USE CASES • Digitize construction sites • Measure stockpiles and other objects • Document underground utilities • Digitize indoor and outdoor spaces with Autotags • Visualize and verify 3D models in AR in real time • Perform single-point measurements with RTK accuracy ____________________ COMPATIBILITY • Optimized for LiDAR-equipped devices (Pro series phones) • All ARKit-enabled devices • RTK devices: Emlid Reach RX and RX2, TopCon HiPer CR, Bad Elf Flex Mini, Bad Elf Flex, Trimble DA2, Leica Zeno FLX100 ____________________ TERMS OF USE https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict

The call

The clearest difference is rating: PIX4Dcatch at 4.7 against Proceq GPR's 3.1. PIX4Dcatch also leads on update cadence (fortnightly vs every 4 months) and ratings volume (262 vs 13). Proceq GPR's advantage is in-app purchases (none vs 1) and review sentiment (67% vs 33%). On price, ads, monetization model and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

PIX4Dcatch holds the better App Store score, 4.7 against 3.1. That said, the two scores are not equally well evidenced: PIX4Dcatch has 262 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 67% of Proceq GPR's written reviews are positive against 33% of PIX4Dcatch's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Proceq GPR ships an update every 4 months, PIX4Dcatch fortnightly. The most recent releases landed on August 18, 2026 and September 24, 2026 respectively.
