I did some research and just wasnt finding what I was looking for... POP Mode... On or OFF for v3.872? What exactly does POP mode do? From my understanding it just detects those super quick on/off bursts with the radar gun and isnt used for giving tickets. So why does the redline have it off by default and V1 has it enabled? I read some where that it might slow down the performance of the unit cause it is trying to calculate if it is true pop or not. I am probably wrong though. Right now i have stock settings but X off. Should I turn off pop?
