I've been using the M25 for about two weeks now. I've had 5 alerts, all false. Don't know why. Each time I get the alert, I kill the jammer within 3 secs and then look for the LEO. Each time, no LEO! Today I noticed something really strange, I got an alert while driving in Toronto; this time I didn't kill the jammer as I was stopped at an intersection with lots of cars around. I noticed an ambulance driving the opposite direction as my vehicle. As soon as the ambulance passes me, the alert goes away. Before that this morning on a major highway in the GTA, I get an alert, kill the jammer and no LEO. About 10 mins later, way down the highway, I spot a LEO with a car already pulled over. No alert on my STi at all. When I drove by I couldn't see if he nailed him with Radar or LIDAR. I did see a gun mounted on the dash but for all I know it could just be a Radar gun. It was mounted in the middle of the car right on the main part of the dash. Any thoughts on why so many false alerts??? I'm confused. I have two heads that have a clear view of the road ahead. They are mounted low, almost flush with the honeycomb grille. I have two more heads coming from Blinder Guy; they're on their way as I write; should be here next week.
