Well, this is fun!
I turned on to a road on my way home and began to pick up a low level k band, just one and two dots fluctuating. About half a mile down the road I needed to make a sharp right, as soon as I turned right the strength meter went up to 4 and 5 dots before maxing out about a third of a mile down the road at a speed indicator. You know the ones that just flash up your speed, no police in the area just this portable speed detector.
In the end this was an alert over a couple of minutes which was just under a mile in distance and involved a sharp right turn. Not bad going in my book!
I'm finding I can run on "A" mode without any worries at all, I pick up one set of library doors but nothing else has moved the detector, I think I'll stick with A mode for the time being.
