I don't use one. Out of 6 tickets in the past 10 years, only one was due to a radar gun.

Also, I go to court for every ticket and have only lost 1 out of the six - the other 5 were dismissed as follows:

1. Officer didn't show up to court - ticket dismissed
2. Officer didn't show up to court - ticket dismissed (this was the radar ticket)
3. Judge agreed with me
4. Guilty! (did not fully stop at stop sign)
5. Officer was late to court. Judge chastised the officer and then dismissed the ticket.
6. Judge agreed with me.
