that successful defense begins with good intelligence about the enemy. Valentine One has a patented warning system relying on both forward- and rearward-facing radar antennas (front and rear laser sensors too). It goes beyond Ordinary Radar Detectors by telling you -- on every alert -- where to look, and how many to look for. Once you have this intelligence report, you can easily decide when to defend, and when you can simply shrug off a non-threatening alarm.
