The only way to reduce falses is by reducing sensitivity or limit the sensed "bands" which you can do either manually with this detector.

Since there is very little K-band used by police in my state, I could probably safely disable that band altogether

Refer to his videos!I do have one area on my way to work that consistently gets false Ka band alerts and I wish that I had gotten the R3 for that -- however, it's not worth $100 in my mind.

This R1 replaced an Escort X50, which served me well but became increasingly prone to false K-band alerts on the highway

It found all the police cars and all the annoying K band speed signs in and around construction
