Hello All, I just ordered the pro 58 from roy and was wondering why when i drive by other cars i get a quick k or ka band alert of 4 that quickly goes away. I have been quite suprised at how far away i can detect my local speedtraps but this is a bit annoying. I have my detector mounted how on my windsheild and set to city 2 mode. Are there any reccomendations to improve my units performance. I was considering the valentine 1 or passport but was put off by the high price being I am a commuter student that does 5-10 over when i absolutely need to. I guess do the higher end units false like this?, I can understand no radar detector can filter out the k door openers at stores like meijer but is there any way to do away with the random car drive by falses?
