A portable ultrasonic flaw detector known as the Sonirail is easily operated, and simple to adjust. The electronic apparatus, enclosed in a metal box, is connected to a probe stick which the operator slides on the rail. Indications are given audibly by means of a built-in loudspeaker, supplemented by visual signals on a milliammeter. An operator can identify common defects and estimate their size. The equipment is particularly suited for checking at fishplates.
