On the way back from Grove City to Erie PA, (I-79 North) Got hit three times with I/O. All three times the State Trooper hit the vehicles in front of me before our vehicle got tagged. Awesome K Band detection with the Redline. Never saw the trooper until very close up, but none the less, the Redline was stellar. The PSP were VERY selective with their shooting, very hard to detect, but we came away ticket free!! Thanks Belscort!
