The Next Step in ACFM Evolution

Over its 30-year history, ACFM® technology has developed a solid reputation for accurately detecting and sizing surface-breaking cracks through paint and coatings. The original TSC Amigo ACFM instrument has earned a reputation for ruggedness, reliability, and ease of use. As the industry demands increased performance in speed, signal quality, and portability, it’s time for an evolution. It’s time for Amigo2.



  • Accurate sizing of surface-breaking cracks
  • Inspect through paint and coatings
  • Less cleaning compared to other methods
  • Up to 10 times faster than the first generation
  • Legacy probe support
  • SENSU 2 probes for high-speed, large-array* applications
  • One or two-person operation (e.g., confined spaces)

Faster Inspections and Better Data

Amigo2 is engineered around a highly advanced signal acquisition and processing system able to process data significantly faster than the original Amigo, for a data range that’s 14 times better. This offers you smoother, higher resolution indications that increase the detectability of small defects and the coating thickness through which you can inspect.

Portable Unit With Embedded and Remote Software

Amigo2 is a self-contained unit incorporating electronics, multi-touch display, and storage in one rugged enclosure. This removes the need for a remote computer and cables, enhancing portability. Of course, those of you who still wish to use a remote computer still can.

A New Platform for Evolution

Amigo2 features a SENSU® 2 connector compatible with the latest generation of ACFM single element and *array probes. The SENSU 2 connector supports up to eight digital inputs for high-speed, large-array* applications.

Together, Amigo2 and its Assist software are fully designed and ready to support the evolution of ACFM probes.

Available Probes

SENSU 2 Probes Features

  • Faster than the previous legacy probes – 2 to 8 outputs
  • Connectorized for convenience. Easy to swap probe cables.
  • All probe data stored in probe’s memory.
  • Integrated buttons optimise the inspection workflow
  • LEDs to indicate scan status
  • Ergonomic design

Backward Compatibility With Amigo and Pace Probes

Amigo2 comes equipped with a connector supporting the use of all Amigo probes—*array and standard manual probes—simply by importing the relevant QPC files. Pace® pencil probes are also supported through a dedicated SENSU connector. Furthermore, you can connect several probes to Amigo2 at the same time, rapidly switching between them in the software.

The Essence of ACFM: Assist

Experienced ACFM operators will feel immediately at home—with familiar Bx/Bz traces and butterfly taking center stage on the Amigo2 screen—while the multi-touch interface offers a highly intuitive access to all software functions in ribbon form.
