Operation

The following four frames show the equipment being used correctly in accordance with the the ACPO guidelines.

As the shadow strikes the motorcycle, the officer starts the time.

As the police vehicle reaches the point where the time was started, the officer starts the distance measurement.

When the motorcycle reaches the second marker, the time is stopped.

When the police vehicle reaches the second marker, the distance measurement is stopped and the target vehicle's average speed is calculated and displayed.
