I bought my Bel RX 65 back in the fall, after getting pesky ticket in a construction zone that could almost have paid for the thing.
After a few months, I enabled POP (in Alberta Canada), "just in case." Prior to doing so, I'd invariably had good warning of those curb-side donut vultures in their Ka band photo radar vans. Usually, I'd estimate, a hundred yards, maybe... Plenty-o-warning, suffice it to say.
Then, one fine day, when fortunately I'm on the speed limit, I get all of about 10 feet from one of them before getting a warning. Was this some new, low power unit? Maybe just a very effective directional antenna that doesn't emit much off the back side so that approaching detectors can pick him up.
Then I read on this site that the POP setting may decrease sensitivity, so it's off again, as of this weekend.
I've been scouring the usual places for these passive predators, so I can make a comparison of the settings. You know, make 12 passes, to compare city/hwy/auto scan senstivities with Ka-Intl pop vs no pop, then Ka USA with pop vs. no-pop.
I have found 2 of them to play with this weekend, but darn if they didn't drive off before I could get in more than 2 passes. I'll report back on what I discover, with careful estimates of the detection distances.
By the way, I had a wonder drive to and from Red Deer from Calgary last night at a reasonable but speedy speed, thanks to the Bel and a willing rabit to lead the way. On the way back, a fool zipped along very quickly, and 20 minutes down the road...you guessed it. It was two cars that were attending his this fellow's road side interview. Not an amiable chat, I'd imagine.
The nice thing was, I was picking up the RCMP's Ka signal for miles before I got to them. I wish I'd zeroed my trip-ometre, but I'd say 4 or 5 miles. Detector just kept beeping and beeping and beeping.
I've never enjoyed video games, but having the detector really does add something to the driving experience, dont' you think? Something of a real life video game.
