Best suited to:
Recommended array: GX2
Recommended array: GX1
Cover more ground
Collect multiple parallel profiles in one pass instead of uilding a grid line by line.
See results during acquisition
View georeferenced radargrams and time-slice information in the field rather than waiting until the data is returned to the office.
Produce repeatable mapped data
Combine wheel-positioned GPR data with GNSS, project coordinates and survey linework.
Use one platform for two very different applications
Exchange GX1 and GX2 arrays without purchasing two complete cart platforms.
The GX2 transforms the GS9000 into a high-density subsurface utility mapping system. Its 11-channel, low-frequency GPR array captures an 83 cm-wide swath in each pass, helping operators detect and map buried pipes, ducts, cables, voids and other subsurface features. Live georeferenced data lets SUE teams review coverage on site and produce accurate CAD, GIS and project-coordinate deliverables.
1. Plan the survey
Load satellite imagery, CAD information, project coordinates or survey control.
2. Collect dense multichannel data
Survey an approximately 0.82 m-wide swath with 11 channels in each pass.
3. Review data live
Examine radargrams, georeferenced time slices and marked features while still on site.
4. Interpret and digitise
Add points, linework, tags, photographs and field observations.
5. Process and deliver
Merge survey areas, apply processing and export mapped information for the customer’s CAD, GIS or reporting workflow.
Units come with two batteries and a certificate of compliance.
This lamp is a highly manoeuvrable lightweight solution that allows operator flexibility with a rechargeable 18V battery. That maximizes operator safety and time on task.
The C4 Nomad contains 4 high flux-UV LED emitters that have a built-in static-electric discharge circuit to allow the lamp to perform in all environments regardless of ambient conditions. The REL LED C4 Nomad-GO integrates both UV-A and white light emitters.
That maximizes operator safety and time on task. The C4 Nomad and Nomad-GO are designed for all intensity requirements of Fluorescent Penetrant Inspection (FPI) and Magnetic Particle Inspection (MPI).
The C4 Nomad and Nomad-GO Glo-Black LED UV-A Inspection Lamp can both provide a 220mm diameter of UV-A intensity > 1000 μW/cm² at 38cm. The integral filter in the UV-A emitter limits the visible light at 20 lux at 38cm and 5 lux at 90cm. The LED white light provides an intensity > 7500 lux at 38cm. The lamp’s electrical components are sealed and passively cooled within an engineered finned housing manufactured from military grade aluminium. This allows the lamp to perform in the harshest environments.
The Nomad can be purchased in the Liquid format which provides a 2m light guide.

The GX1 transforms the GS9000 into a high-resolution structural assessment system for concrete slabs, bridge decks and pavements. Its dense, dual-polarisation array captures detailed 3D data across wide areas, supporting reinforcement and cover mapping, moisture and deterioration assessment, and analysis of asphalt and pavement layers. Live visualisation helps confirm survey coverage on site, while post-processing tools produce clear, report-ready condition maps.
1. Define the inspection area
Import the structure, bridge, pavement or survey background.
2. Collect closely spaced profiles
Capture 35 longitudinal and 15 cross-polarised channels with dense spacing.
3. Review coverage in the field
Use live radargrams and time slices to confirm that the required area has been captured.
4. Process the dataset
Apply velocity, gain, background removal, migration, filtering and topographic correction as appropriate.
5. Generate diagnostic maps
Create depth slices, reinforcement maps, layer information or application-specific condition maps.
6. Integrate with the engineering assessment
Export figures, mapped anomalies and raw data for inclusion in the engineer’s final interpretation and report.
