Question Spurious Laser Indications on Escort 8500

This just started last week. Once every couple of days, my 8500 would go bonkers and indicate laser repeatedly when there is no laser (I have yet to see a real laser hit in south florida). This has happended on the highway, local streets, and in the middle of traffic. The next day, everything is normal. Anybody else have this problem? If so, is there anything that can be done or is this the first sign of failure? The unit is almost 4 years old.

Thanks, Yuan

Following an SUV too closely? Sometimes the 3rd brake light on some SUVs will set off the laser detection. Other times it could be an anomaly from other sources. My V1 has done it in the middle of nowhere a few times.

Mine did this as well, so I turned off the laser detection. 9 times out of 10, if your laser warning goes off, you've already been snagged (DAMHIK).

Just a thought, alot of new vehicles have a backup sensor to warn the driver. What type of signal are they emitting? Could be one source of false alerts.
I have had some laser alerts in FL, some seemingly random, some consistant when going through certain toll booths on the turnpike, I think they use it for the license plate cameras.

May I ask? Are you near any type of "airport" when this happens?. Lasers are used as a help in guidance systems for approaches to airports, mine goes off in certain spots near my local large airport. The "back-up" type systems on the SUV's, etc.... , are of a "radar" type I believe, they send out a wide swath of a signal which returns to the unit. and ultimately sets it off. "Lidar" (laser speed enforcement) uses a small beam of light which is aimed at your car. As the beam becomes shorter, the unit measures this change and calculates your speed. Radar sends out a wide width ?beam that bounces off your vehicle, then bounces back to the radar unit. Usually this "beam" (or whatever) has to bounce off your vehicle twice and be sent back to the policeman's radar unit to get an accurate reading. I may stand corrected by some of our fellow BMW riders who are cops, but that is why if you "stomp" the brakes on just as the unit hits you, sometimes it produces a bad reading. Of course, if one of your buddies is right on your tail, this is not a wise idea.

I've disabled the laser on my older Passport 8500 - here is what I posted last year:

I've had my 8500 for over two years and have been happy with it. A few weeks ago while out riding I hit the horn on my bike and got a Laser hit. I didn't think much of it, but now every time I hit the horn the Laser alert goes off - even while using it in my car.

I just talked to passport and they said they've heard of this happening in a some units - something about the electrical system of the car/bike. They wanted $50 to install some kind of filter and there are no upgrades to the new X50 available.

Talking Beware in Texas

Here in Texas, the F-16 and F-18 pilots use motorcycles as target. It happens in the open country when they like to play.
A pilot told me they enjoy the sportsbikes more but don't worry its practice for them.
West of Abilene, Tx, the B-1s do the same thing but not as much.

I was not near any airports when my laser went off.

I'll contact Escort to see if an upgrade to X50 would solve this problem.

I have a Garmin 2610 on the dash of my car and a V1 mounted up higher on the windshield next to the rear view mirror. Occasionally when I point the remote control at the 2610, it triggers the laser detector on the V1.

The horn setting it off by an above post correlates to my own experience. I found a bad connection with the power and when the power fluctuated, my laser mode detector went off. I suppose the horn can also tax the amount of power to do the same thing. I, too, have the new escort.
