What is laser shifting? Initially I was all in for the Valentine unit, but now am looking also a the Escort 9500ix, sort of like the GPS and Speed Read-out. Little confused on Escort; they seem to have many different units. Maybe you start low and work your way up. But I must say that I have really slowed down in my selection process.

 

Dumb question, red of course!

 

Whatever you get, get one you can synch to a database with. TSR (traffic sensing radar) is being used here in Colorado to detect traffic flow and post on signs time estimates for travel to a given destination. So as you cruise down the highway, your radar goes off everytime at the same spot. Some of the systems can be programmed to pick up the TSR spots and only go of if a second radar is detected.
