The Amigo represents a significant advance in ACFM topside inspection technology. The smaller, lighter package, has the added benefits of a longer battery life and support for simple array probes. The system allows for rapid scanning using hand held probes as well as at least 5 hours operation time on a fully charged battery. The Amigo is capable of inspection through thin metallic coatings or through non-conducting coatings several millimeters thick. The Windows based software allows for ease of use and compatibility within other Windows applications.
