Vortex said that radar detectors are useless against laser because alert comes too late. This is probably true, but I have heard that detectors are able to detect lasers when they are used on cars in front of you. Is this true and do you have some time to slow down?

it falls into the category of luck in most cases... if the laser beam reflects off the car just right and you detector see this reflection it can catch it. That said most RD's aaren't that sensitive and won't see it. The V1 gives you the best bet, as it's super sensitive to laser, that said it also falses to laser a bunch from cars with laser cruise control and anti collision systems. it also depends if the officer decides to shoot the car ahead of you, they don't always shoot all cars and the laser gun only fires when the trigger is pulled. so you are trying to catch a reflected beam of light that is usually only 3 feet wide when 1000 feet from the gun and only transmitting for 1 -2 seconds at a time... there are times I have been directly hit with laser and my RD didn't catch it let alone catching a reflection of laser from ahead. Don't trust it, once and a while you might get lucky but it's just that, luck. Jammers are the only consistent defense.

It's possible but really rare. It's kind of like winning the lottery. Sure you can technically do it and there's people who have done it before, but the odds are really really stacked against you so it's not a sound investment strategy. Similarly, counting on laser scatter to save you isn't a good idea either.

If you're looking for protection that you can reliably and consistently count on, laser jammers are the proper tool, not depending on your RD detecting scatter.

Just yesterday, on Interstate 5 in Washington, I was hit twice by State Troopers who were standing on the roadside (I sure hope they don’t get hit but that is a really bad place to stand). Both times they were around a bend and not too far away from us cars as we rounded that bend. I could see the Trooper moving the radar from car to car around me, including cars close in front and beside to me. My R7 never went off. My ALP did, but my R7 did not. In fact I could see the Troopers keep pulling the triggers on me like they couldn’t get a reading.

Thanks for answer, what about instant-on radars, is it easy or hard for detector to detect scatter of radiowawes when they are used on car in front of me?

I have had good luck picking up radar scatter on my R7, from instant ons. In fact, the Troopers in Oregon seem to be using it on my trek on Highway 26. They never used it before this. But if you have traffic ahead of you, I get scatter great off of them. No problem. Only problem is if you are the first. The other day I was going about 75/55 on that route, just waiting for the troopers. A VW came up and tail gated me so I pulled as far right as I could and he just flew past me. Wasn’t but a few seconds, just as he went around a bend ahead of me that the R7 went off. From past history I knew if it had been always on I would have picked it up earlier. Sure enough, right around the bend was the VW having a discussion with a trooper. I am pretty confident that it was an expensive discussion.

Careful, welcome to the forums! Detecting lidar scatter should not be part of your layered defenses against LEOs. It's really sheer luck as the others have suggested. I've experienced it a couple of times with my V1, but it is uncommon. I think the V1 might be the only detector with a strong enough laser section to pick it up. That, in itself, leads to new problems during the daily commute in that it also detects every Volvo, Infiniti, etc.

What everyone else said. I've had one quasi-laser save with a detector - 1500+ miles w/ DFR7

Welcome to the forum! Take your time to read up and you'll be well-informed before long :) Even if you decide not to get laser protection, you'll better understand the risks and that awareness may keep you from having too much fun at times/on stretches of roads that are difficult.

Thanks for everyone who answered! Laser is almost not used here (althought they have some ProLaser 2 guns), but I was just curious, this is surely one of the RD myths.

I got a scatter save once before I got jammers. A VW ahead of me was shot and my Redline picked up scatter before the cop shot directly at me. Gave me a few seconds to bleed off speed. But that's not really going to 'save' you in the other 99.9% of encounters.

Come to Cali, laser now accounts for about 60% of all speed citations.

Radar is another story, radar is a very wide long range travelling wave (compared to laser which is a very narrow beam). If an officer turn on his radar unit then a good RD will pick that signal up for miles (terrain dependent) . they some times do run instant on where they only trigger for a short period then turn it off. A good RD will pick up that burst of signal from a few miles (terrain dependant of course) and you will get the notion that there is something coming. here is an example of I/O radar and my RD saving me. Radar - R1 PSl+25 Rolling Selective I/O Save if the officer had been shooting laser rather than radar I would have had no warning and my laser jammers would have to have done something.

It's easier to pick up laser scatter on a motorcycle where the detector is closer to the headlight. I've picked up laser scatter many times with my Bel GX65. I have yet to be hit with laser with my R3. I try to stay middle of the pack in areas I know where laser is used.

The last laser trap I went through was around a curve, and I was shot point blank at about 100 feet. :police3:

Can’t prove / have no data but I think laser detection was easier years ago (1990s) than today. I swear I got a good laser warning in 1998 on my passport 4500 coming down I-95 through Baltimore- like 5 seconds behind a line of cars

Did you disable your ALP after it went off?

R3, never had it go off when hit. R1 falsed all the time even when no laser was around, turned it off. V1 falses alot but has picked up TSS, XLR and UL LRB, but only when hit directly, never scatter.

The second time I did. The first time it did itself after 4seconds because i am still getting used to killing it manually.

Good man. Gotta kill them quick so they don't get suspicious. ;)

Some cops will hit you with laser even when you aren't really speeding and it's more likely to occur when there's no traffic around as they can't use visual estimation. So I think it's still good to have RD laser detection to catch hidden cops in these cases. If you have a visually and/or audibly loud car, you're going to be a magnet.

I have had a few laser saves from “scatter” over the years with my V1 when the LEO has targeted the vehicle in front of me. I don’t encounter a lot of laser. It has been probably 3-4 years since I have experienced a LEO targeting a laser/lidar gun in my direction.

I assume you mean the trooper was moving the laser gun from car to car. If it was radar you should have gotten an alert no problem.
