The Equotip Piccolo 2 and Bambino 2 are both suited for on-site hardness checks of metals where the test indentation should be as small as possible.

Collect high-density, georeferenced GPR data across wide areas and view the subsurface in 3D as you scan. Choose the GX2 array for SUE and utility mapping, or the GX1 array for structural, bridge and pavement investigations.
Best suited to:
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.

For real-time monitoring and user specific conversions

Metal heat treatment allows mechanical properties to be changed so that the metal will be harder, stronger and more resistant to impact. The Piccolo 2 is used to monitor and document the strengthening of high integrity metal components for the automobile industry. Automotive Lifting Technology are subject to stringent requirements that need to be met by an automotive lift manufacturer. The portability of the Piccolo 2 is ideal for testing bulky lift components.
For quick on-site hardness checks

Scuffing can lead to catastrophic failure in engineering components. E.g. in turbines of power plants where wearable parts are required to endure high mechanical stress. The Bambino 2 with the DL probe can be used to ensure that stressed recesses, joints and edges are of the correct hardness to minimize scuffing. Cold rolling is often used to decrease the thickness of sheet metal. To avoid spall fracture, Equotip and Equotip’s Leeb hardness unit HL are used as a standard for roll testing in rough environments. The light-weight Equotip Bambino 2 lends itself to quick intermittent checks of rolls.
The Equotip Piccolo 2 and Bambino 2 are both suited for on-site hardness checks of metals where the test indentation should be as small as possible. The robust design and large display allow the user to work at dusty worksites with low visibility. Both products also display metal hardness in all common scales.
The Equotip Piccolo 2 offers the same features as the Equotip Bambino 2, but has the following additional features:
Equotip Piccolo 2 and Bambino 2 are supplied with a D impact device. It can be interchanged with an optional DL impact device, which is useful for measurements in restricted areas.

The portable hardness testers used most commonly for metals are based on the Leeb rebound method inventedby Proceq SA. The Equotip Piccolo 2 / Bambino 2 operate according to the Leeb principle, in whichthe hardness value is calculated from comparing the energy of a test body before and after impacting on asample. This Energy QUOtient (EQUO) is quoted in the hardness unit HL and is calculated from comparingthe impact and rebound velocities (vi , vr) of the impact body. It rebounds faster from harder samples than from softer ones, resulting in a greater energy quotient which is defined as 1000·vr/vi.
Metal hardness can be displayed in different hardness scales: HL (Leeb), HRC (Rockwell C), HB (Brinell), HV (Vickers) and so forth. The Equotip Piccolo 2 / Bambino 2 enables measurements to be rapidly taken and displayed in any chosen hardness scale. The Equotip Piccolo 2 has an additional feature that lets the user customize conversion curves for special alloys and also allows the user to convert hardness readings into tensile strength.

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.
