I have a hardwired Escort Passport 9500ix and Escort Live in my whip. On the way to Santa Monica (10 freeway West) this morning before PCH, I passed a slow car on the "fast" lane. Just after I passed the vehicle going about 80 I saw a CHP officer with a radar/laser gun targeting vehicles on the freeway. Thankfully I wasn't going too fast and he didn't pull me over; however, my Escort FAILED to pick up the signal and alert me.
Are CHP officers using a different band or should I now start thinking of buying the Escort Max or V1? Any input appreciated.
