The LEO's have upgraded to Laser guns here a couple of months ago and I almost found out the hard way.
I had about 4 alerts in 2 weeks with my REdline alerting to Laser in which I thought were "falses" due to the early morning sunrise (My older V1 was notorious for this so I figured the REdline was probably the same so therefore I didn't put too much faith in a RD's laser alert/non alert). For each of the 4 alerts I scanned around for LEO's and couldn't find any at all. I also run a LI but normally don't turn it on for my trips from home to work as it's only 3 miles max and I run about 5 miles over the PSL and LEO activity in my area was sporadic at best with no known laser activity.
On the start of the 3rd week just for shi** and giggles I turned on my LI for the short trip to work and I'm glad I did because that morning I was >10 PSL (danger zone for getting a ticket in the city where I live) and my REdline and LI starting going bananas and about 1/2 second later I spot the LEO at my 10 O-clock. I tried to indiscreetly slam the brakes and kill the LI as quickly as I could. Either thru luck or a good Jam he didn't pull out behind me. I have noticed the LEO's like this spot lately because you get really close to them and get clocked before you can get a visual.
So I have to say without reservation the Redline seems to pick up the Laser pretty darn good.
