How well does the Bel Vector 940 detect instant on? I was wondering if it gave decent warning if a LEO was using I/O in the area. Just bought it a few weeks ago and the LEO's here are beyond lazy. All of them use C/O driving down the road. I have only come across one speed trap in about 6 months (this weekend). There were two police cars parked side by side in the middle of a vacant parking lot. lol Those were actually using instant on, so I began to worry that eventually I may encounter the one LEO that actually uses it.
