Ever hear of this speed detection system used by cops?

[82 GT]

I got a speeding ticket last Sunday. The cop said I was doing 54 in a 35 zone. I never got a ticket I didn't deserve until now.
I said to him "what did you use.....vascar?
He said "no, it called Robic and it's done with a stop watch"
I tried to look this info up online but all I found was that "Robic" is a type of stopwatch.
Has anyone heard of this system and know how it works? It sounds similiar to Vascar which means it's prone to human error.
I'm going to fight this one and I'm trying to dig up as much info on it as I can.
He was obviously a rookie because he made tons of mistakes when he pulled me over.
He never noticed that my daughter and I were not seatbelted.
My license and registration has two different addresses because I moved last year and he never asked if I had a change of address card and I accidently gave him an outdated insurance card that expired 10/02(the new one was still at home on the fridge....LOL)
My question is: If he couldn't notice obvious stuff like that then one must wonder how accurate he was with that stopwatch.
I have a very good feeling I could beat this ticket.
