Good deal for the R4.

"Just drive slow" crowd, save your breath and move on to the next deal.

As a police officer, I love radar detectors because people that have them tend to drive within reason. That being said, almost no departments use handheld radars anymore, it's either moving radar that is almost always on but can be set to stationary mode or handheld infrared lasers, or lidar, such as the Pro Laser Iv. These units will give you warning for moving radar but they won't for lidar. The cone for the laser is 3 feet at 1500 feet, and it doesn't bounce around down the road like radar does. The return speed is less than a second and we aim it at your grill area, not your windshield. I may shoot a laser at you and it doesn't even register on your detector.

That being said, people with detectors tend to be safer drivers, definitely driving slightly above the speed limit but not below the speed limit which is statistically more dangerous to a large extent. This deal seems good and the brand is reliable.

Anyone who wants the R3 over the R4 is crazy. I own both and the R3 has way more false alerts than the R4. I love the more advanced warning of the R4 over the R3.

Except for when you cause a fatal crash. Of which there were ~43,000-ish last year. Of which ~10,000 were speeding related.

But of course killing someone in a speeding crash is definitely not "imposing on others", and it would NEVER happen to you, and if it did I'm sure it would somehow be the fault of the guy going the speed limit. I'd link you studies, but you're probably in too much of a hurry to read them.

Anyway godspeed, I know I won't change your mind, but it doesn't make you less wrong in your above statement.

And back to the deal - these things barely work, but if it makes someone happier with a $280 placebo effect - knock yourself out.
Barely works? Must be why I haven't gotten tickets since I got my escort 8500 back in the day 🤣. In suburban hell holes, it would save me 3-4x per day! The only option is to speed. The lights are timed to catch you at every single one unless you're going about 12 mph over....hmmm, no, not a conspiracy at all. Not to mention all of the random speed reduction zones to entrap you. Then you have hwy.... I'm not going 60-70 when it's a 80 mi drive. GTFO

according to first google search.

"According to federal and state studies, driving slower than the average speed is more likely to cause an accident than speeding. Driving too slowly can make other drivers around you constantly brake and speed up, which can be frustrating, cause confusion, and lead to an accident."

https://www.croweandharris.com/bl...20accident.

https://ww2.motorists.org/wp-cont...-sheet.pdf
"Isn't slower always safer?
A. No, federal and state studies have consistently shown that the drivers most likely to get into accidents in traffic are those traveling
significantly below the average speed. According to an Institute of Transportation Engineers Study, those driving 10 mph slower than
the prevailing speed are six times as likely to be involved in an accident. That means that if the average speed on an interstate is 70
mph, the person traveling at 60 mph is far more likely to be involved in an accident than someone going 70 or even 80 mph."

Even if going more than the speed limit yourself, if cars are lining up behind you, safest thing to do is get over and not imped faster traffic.

Radar detector have saved me 10+ times over the last 10 years whenever I travel on long stretches of highway and do 10-15 over the speed limit. I have the R3 model and it warns me a good 1-2 miles from where a cop is posted with a radar gun.

You are actually the one that is wrong. If you get a laser alert, and it is not a false alert, then you received a direct hit. Laser is an extremely narrow beam, even at a mile away. There is literally almost no dispersion.

The above said, having a good laser detector is still a benefit. If it picks up a hit from a trooper a mile away, it gives you time to slow down and hope he gets somebody driving faster than you before you pass him. Not only that, the alert might prevent you from driving even faster and getting an even bigger ticket - or getting arrested for reckless driving.

So what you are saying is for a decade or longer, I've just been lucky avoiding LIDAR driving around the country, which is essentially undetectable until it's too late, according to you, only receiving a handful LIDAR hits on my detector with no cops in the immediate area visible. I have seen cops after a hit not line of site. Seems reasonable.

Lucky for you - most state police are still using KA-Pulse band (which is still hard to detect, but at least you can detect it w/o a direct hit). Laser is not used by that many police departments, and it's usually a handheld unit vs mounted in-vehicle. That said, I *was* nailed by a NY State Trooper years ago - so I know they use it in NY. In that case, I left my high end Escort radar detector at home for a trip to Niagra Falls - but, like I said, you don't see a lot of Laser use in many states. Some states, like NY and maybe Virginia, I believe, use a lot of Laser.

Soooo... depending on where you live, you may either be damn lucky or it may be that your state does not use much Laser.

AFAIK laser jamming is legal everywhere (just light) but expensive. Also would love to know if laser has problems with rain, which is what I've heard.

Most the laser I ran into was California.
i get KA constantly here in Washington, then verified always visually… I think if I've learned anything today is if the cop is sitting perpendicular to the roadway, good chance its laser. but it 1000% detectable with scatter or I'd have LOTS of ticket now, and I have none.

I know there is a corridor in Washington state that is known for vey aggressive speed enforcement. That said, it doesn't sound like you're going to believe me on LiDAR detection and that if you detect it - you probably had a direct hit. That's fine, no sense in arguing about it - you don't have to agree, but maybe read this. Radenso makes some of the top end radar detectors you can buy, and here is what Radenso says about LiDAR and even their own detectors' ability to pick up LiDAR:

While sometimes radar detectors (which often have laser sensors built in as well) can pick up a LIDAR beam that is aimed at the car, it is also normal for the sensor to miss the laser shot completely since the beam is too small. And of course, since laser is being used and not radar, the detector will never alert "Radar" as a result of a laser shot.

To get true protection from laser, we do not recommend relying on a radar detector from any brand including ours. Instead, consider a laser jammer for complete protection.
In conclusion, there are several reasons your radar detector may not alert when you expect it to. While it is normal to be surprised by the level of advanced false alert filtering in high quality, modern radar detectors, your worries will go away the first time you detect a police officer from several miles away and score a nice save!

I'm going to look into laser jammer now for sure. What I think you need to understand is real world LIDAR can have MANY variables. If you understand light refraction, shooting through windows, humidity, rain, all this plays a part. You don't have to believe it. It's why space lasers are hard and the lasers we tested on the 747 ABL missile defense test plane. You MAY be correct in Arizona, 8% humidity at dusk. But that's not the real world. Try that raining sideways on I-5 in Olympia. Or dusting snow in Spokane. All I can say is with these real world situations, I have been waaaay over the speed limit, especially between Nevada/California had multiple laser detections, and then ran into the car a mile later. I do need a jammer though.
