The Shark Calibration System produces precise measurements of a damaged frame through wireless communications, and then compares the results to exact specifications downloaded from the automobile manufacturer. Three samplings are taken of each measurement. Those measurements can be monitored live, during the pulling process by which the frame is straightened.

Shark uses ultrasound technology to acquire data. Probes installed at specific points on the vehicle frame transmit signals which are received by microphones located on a lightweight aluminum beam. The beam is connected to a computer console which is ruggedized for body shop use.
