Proceq GP8800 Live Pro GPR easily scans in tight spaces, on curved surfaces, overhead, and close to the walls of concrete bridges, structures, and pavements. This handheld model operates with Proceq’s Stepped Frequency Continuous Wave (SFCW) technology, sweeping through a wide range of frequencies during scanning instead of the one-channel operation of pulsed-radar units. The 0.4–6.0GHz SFCW operation achieves penetration depths to 25.6in (65cm) with high-resolution characterization from a single antenna.
The unit detects reinforcing bars and steel mesh, secondary layers of reinforcement, tendon ducts, cables, conduits, and other embedments. Voids, inclusions, and discontinuities are also identified, and slab or wall thicknesses are measured from a single side. Ground penetrating radar is the ideal technology for structural investigation, as-built verification, rebar and embedment detection, and thickness measurement.
The exclusive wireless tracking wheel adjusts between trailing and sidecar configurations for flexibility in cramped environments, and to permit cross-polarized scanning. The cross-polarization method combines data from two scans in perpendicular directions from the same area, significantly increasing scanning sensitivity and resolution. For scanning in narrow areas with as little as 2.5in (64mm) of clearance, the battery pack can be removed and tethered to the scan module with a USB-C cable.
The GP8800 connects over encrypted Wi-Fi to the user’s Apple iPad with iPadOS 13.6 or later. Wireless connection to the iPad allows independent operation with no cables at ranges up to 65ft (20m). Proceq’s Live Pro software leverages the powerful post-processing capacity, high visual resolution, reporting, and collaboration features built into the iPad as an ideal platform to view, collect, and distribute results. Visualizations, graphics, and report data can be shared instantly to the cloud from any location.
Data migration processing displays results with Realistic 2D and 3D imagery throughout the detection depth. Using Apple’s ARKit™, augmented reality (AR) images can be overlaid on the real-world environment when viewed through the iPad, providing real-time, in situ imaging of subsurface elements.
Memory and display capabilities allow straight-line scans up to 3,281ft (1,000m), but the unit is better suited ergonomically for shorter line scans and defined area scans up to 1,076 ft² (100m²). Review modes include non-migrated scan, migrated heatmap, and time slice/depth slice. CSV and HTML data and JPG, PNG, and SEGY images can be shared with clients and stakeholders.
Data is tracked and secured in the cloud through the Proceq Logbook. In addition to live data sharing, this allows post-processing and data review from any iPad signed into the connected Proceq account. All measurements, changes, and settings are tracked and included. Geolocation, photos, audio notes, and comments can be added to the scan for quick reporting of details to off-site personnel.
The antenna is completely contained within the compact housing. The wireless tracking wheel attaches to any side of the housing to allow scanning in any direction and easy cross-polarized measurements. Powered by four rechargeable flight-safe batteries, or alkaline AA batteries, the unit operates for up to 2.5 hours under continuous use. A tethered aftermarket 5VDC, 2A power bank can also be hot swapped for the battery pack to extend operating times to eight hours on large projects. Optional accessories include an extra battery pack with rechargeable AA batteries and an ultralight telescoping alloy rod for hard-to-reach areas.
Permanent operating software for the GP8800 Live Pro GPR is included and features access to Proceq Workspace. Free support, updates, and new releases are provided for a five-year period after the initial purchase. The software remains fully functional after five years, and support and updates can be continued with the optional purchase of a five-year extension. Apple iPad hardware and operating systems can be replaced or upgraded by the user at any time for improved performance with no need to replace the GPR sensor.
A Wi-Fi module, a telescopic rod with iPad holder for convenient access to hard-to-reach areas, a USB-C cable, carrying case, wrist loop, battery pack, chalk, and two sizes of grid paper are also included. Grid paper in various sizes, marking chalk, and extra battery packs can be purchased separately as accessories.
