Without going into detail... I just returned home from an interaction with local law enforcement using a timing device called ENRADD(?) and could use some advice.

Yup, Googled it right after I posted so now I understand what it is... and still think I should speak with someone versed in PA traffic law.

This is a speed detection system that is currently in use in PA & OH. It uses sensors appx 5 feet apart to calculate the time distance speed equation. Highly dependent on calibration every 60 days and proper installation.

Unit is unable to to work on a wide roads (i.e. four lanes highways either two ways in each direction or four lanes in one direction) due to the limitation on maximum distance between sensors thus uncapable of distiguishing with absolute accuracy if second set of sensors was actually triggered by the same car that triggered the first set of sensors (i.e. first set of sensors was triggered by the car moving in one direction and the second sent was triggered by the car moving in opposite direction).
ENRADD unit has to transmit the speed-reading data to the police car over the radio frequency. Usually ENRADD unit requires two police cars to operate: one reading the unit data and second police car is actually making a traffic stop. Two cops have to show-up at the trial.

Good Luck
