My R1 is visor mounted and I have had one confirmed laser alert. I have not been able to justify the purchase of Alps, and at this point I am thankful that my R1 seems to detect laser.

Use Waze and hope the LEO shooting lidar is marked. And always keep your eyes open when you're exceeding the PSL.
In 2014, I was on my way back east from Indi in a rental. In Ohio, I reached the crest of a hill and BAM, Magnum screams laser, LI yelled Ultalyte 20/20, I slowed rapidly and killed the jammer. The guy following behind me wasn’t so fortunate. He got yanked. Had he been using a decent detector to collect the scatter, or was more aware of my rapid deceleration, he would likely have been fine. We were cruising well over 90 mph. I had Waze running but the Leo was marked on the other side of the road, so no warning. He was also obscured somewhat. The LI saved me that day, Waze didn’t unfortunately but it has on many occasions. I currently have a set of ALPs that I use for travel, but I don’t always have time to install them. In that event, I expect my detector to at least notify me when i’m being targeted.

If I offered to give $100 to your favorite charity would you promise to stop commenting on R7 threads until you actually buy one for yourself?

I’m serious by the way I would do it. I promise.

I’ve never gotten an laser alert on my R3 or R7. Both in the field or in testing. :-(

I have a PL3 and DET.
When we tested my ALP Setup I almost swear my R3 picked up both at some point, at least one for sure. Just don't remember which. I guess I could go back over the dash cam footage.

If you speed regularly, which most of us seem to do, you should absolutely have a set of ALPs. You are asking for punishment and it is inevitable.

Is your R3 alerting to the gun, or is it alerting to all the laser back and forth between your jammers and the gun? It all happens very quickly.

Fortunate Laser is not used in my everyday travels, and I feel pretty low risk of being tagged, but yeah I would like to have a set in the future.

I'm going to mount the R7 lower tonight, bottom of the rearview and run through two more poliscan speed camera's tonight and see what happens. Video coming shortly.

But certainly no radar detector has the fancy hardware/software that jammers have to identify guns by pulse pattern though IMO there’s no reason other than cost why they can’t. Pulse capturing hardware isn’t that hard to find and I doubt a radar detector is using those digital capture pins for anything.
At the risk of being pedantic, I have a friend that used to have an old crappy Cobra and when I shot it with my LZ1 it specifically alerted to an LZ1.

You’re right, I forgot about those detectors!

Actually Cobras were generally good at laser too. It was my first detector and I got a scatter save with it. It didn’t make up for all their other shortcomings but credit where credit is due.

The likelihood of alerting to jammer heads that are grill mounted firing away from and not directly at an R3 tells me in all likelihood it wasn't from the jammers....

We can't have it both ways complaining about how the R series isn't good at detecting laser at all- and then pretend it picked up a false from another device when there's a known gun pointed directly at it.

Videos from tonight, all from different locations here in MD. Lowered the R7 on the windshield a bit. I'll be requesting an RMA tomorrow. What an absolute shame in my opinion. The R7 is blind as a bat to Poliscan laser. Absolutely blind. It's a necessity for me here where I live so this will be getting returned. The detector that invented the arrows is where I'll be.

Not to refute your videos, but do you know that the poliscan units were even functional at that hour? Around here we get mobile units that once it's dark they are shut down.

You obviously know your area and it isn't the same as mine but one has to ask that.

Also, rear laser is pretty tough to detect anyway, but if a V1 makes you more comfortable then RMA the R7, it just isn't a good fit for your purposes.

Myself, range is king and laser is whatever because of my area.

Those Poliscan units are on 24/7. If I had my V1, it would have alerted. I've had my V1 give me plenty of range in order for me to slow down. We'll see what the new and improved V1 has to offer.

Are you sure they're 24/7? I don't know if the laws were changed, but if memory serves, speed cams were only allowed in school zones and road work areas. The ones in school zones were only allowed to operate with in given times, based on when school was in session or when there was an after school activity. In the past, with my R3, I've gotten laser hits... not 100% of the time, but I have been alerted. Lately, I've been seeing those units being swapped out with MRCD. In work areas, I've seen K band and one time, I got a laser alert on my R3, while K band was going off.. but I think it was a false laser alert.

I drive by those units day in and day out at all times of the night/morning. I've been living in this area for 20+ years. I know it like the back of my hand and I've been running my V1 for coming up on 11 years now in July. My V1 would have alerted just like it did the other night. I only have one power source in my car, hence why I only had the R7. I'm also not sure they would run a Poliscan unit in an are where they can't turn it on. What a waste of resources.

I will run by each of them tonight with the V1 and record it to show you that they are on.

We've been through this poliscan scenario before with the R1/3 as brought up by @drtoddw. Some folks have circumstances where they feel an R series detector is just not for them. This is one of them, and that's ok. It's all a function of one's individual circumstances and priorities.

We can look at it a little differently if you want to entertain the idea. Was the gun VPR or a unit with ECCM active? If it was not, then yes you detected and alerted to the gun? If the gun was what is mentioned above, it is possible that the chatter between the gun and jammers, including all of the laser reflected off items on the road in front of your vehicle (road signs, painted lines, cars moving in the opposite direction, etc) made it’s way back to your detector.

At that point, the specific pulse rates / characteristics that the R will ignore (we will use “ignore” because we all know that it detects them), aren’t so specific anymore. And again, assuming laser moves at the speed of light, the time between the alert during both scenarios would be indiscernible to you.

Regarding detection and alerting, if i’ve used the terms interchangeably or accidentally in prior posts, my apologies. When aiming the guns in question at the R, I have no reason to believe that it does not detect them. But we know for a fact that it chooses to ignore them and not alert. If anyone has access to a Keysight DC power analyzer, this can be easily tested and visualized.

Agree!
If I didn't drive out-of-area, I would just take my chances as well. ALPs/TMGs are really overkill around here. I've driven over 50k miles per year, most of that in West Michigan. Having VVAZE for laser and a decent detector for Radar is almost bulletproof here.
It's when you get out of West Michigan that the ALPs/TMGs/etc give true piece of mind.

Although hard to prove that something didn't happen, I always enjoy seeing what others face. Thanks

Stick around awhile, you'll see there are no absolutes here.

I run across similar poliscan setups in MD daily. In fact the video with the dual poliscans in series (which are rare) looks like a setup they have on Quince ******* Rd. If this is the case I can confirm they are on 24/7/364 (yes they are off on Christmas). Also, Montgomery County MD does not have the school zone only restriction, as do many other counties.

You appear to be traveling in the monitored direction where the laser hits you from behind after you have passed the unit. Question becomes, does the R7 's rear-facing light tube for laser (I believe it's called Eagle Eye") have a clear view through the back window? With a 360c I always get a frontal laser alert facing any poliscan that is on the other side of the road not monitoring me. I usually get an alert in the monitored direction too, but only after it shoots me through my back window in the rear light tube. At a minimum you should get consistent frontal laser alerts from cameras on the non-monitored opposite side of the road. These cameras deploy multiple spread tracking beams and are not the single concentrated beam as handhelds use. Below is a video of front poliscan tracking vs rear as used in most places in MD.

The testing was performed with a DETC and Prolaser 3. I also have an Ultralyte myself....

Like I said in a previous post I am no engineer - but divergence is a thing and the divergence of a beam from a laser is very very narrow. From it's point of origin to where it hits something there's little to no spread or fan. Sure you can get reflections but those too are very narrow.

Let's for argument sake say at 1000 feet the beam divergence is 20 inches.... Even with a cone that narrow the geometry to hit a small light pipe on top of a detector has to be very direct. It isn't like RF/radio frequency where when transmitted it has a very broad spread.

Has there been legitimate testing to show that any R series is actively ignoring laser hits?
