I have a Valentine 1 in my GT-R and was popped in Howard County last year. The good news is that my Valentine 1 alerted immediately. The bad news is that the officer already had the reading he needed. Luckily the judge only gave me PB&J and that probation period has passed. So unless you have the money to also put in a Laser Interceptor, then having a Valentine 1 or Passport IX (which I have in my DD) will only help you in the case of an officer popping someone else first.Has anybody in the Maryland area had good success with Laser Shifters? Have your radar detectors been picking everything up? Getting ready to install Belltronics sytem in my GTR.
