Ok. So after some reading...This is what I THINK I know.
Ka Guards main purpose is to filter out false alerts from other Radar Detectors? So with if off I might experience some ka alerts when next to someone with a Cobra?
What other sources emit Ka false, I personally have never gotten a Ka false? It is always a cop.
Im sure some people on here leave Ka Gaurd off. What do you like about it and what keeps you from turning it on?
