Driving to Atlanta from Mobile, started picking up C/O KA band for at least a couple of miles. (I thought something was wrong with the unit) But finally passed LEO and WOW! Then on I-85 got several off/on alerts from KA, finally figured out LEO was ahead of me, shooting opposite side traffic. I was amazed at the range of this unit. I do not have LJ yet, was hoping to find some laser on I-285, but it was 2am in the morning. Oh well..maybe next time. Always an excuse to run up to Stone Mountain?
