I had some extra time on my hands and took an opportunity with the light traffic to play with my new MPH BEE III radar gun. I was surprised at the distance I was able to get readings at. If the traffic was relatively clear and light, I could visually confirm readings of passenger cars at 0.9 miles away. I had one more confirmed reading from a local public transit bus that was even further away still, but didn't have enough info to accurately report on the distance of it so I'll leave it out formally. I parked on an offshoot road of a larger neighborhood road and faced downhill (south) pointing towards the road named "800 North", to give you an idea of orientation. You'll see three overhead traffic light systems for points of visual reference. There is the first intersection traffic light, next a lighted protected school crosswalk, and then the final second intersection traffic light in the video you can see. I'll have to get a better camera and possibly some optics so that I can better see further off. I have definitely had my eyes open to the capabilities of velocity radar. Video is immediately below followed by the reference map. Here it is for your viewing pleasure.

0.8 miles longer than a Whistler's detection range.

Nice video! Actually playing around with a radar gun gives you a much better idea of what we're up against. This is a great example.

What was the speed limit there? When I test, I'm always amazed at the number of people that are driving PSL++ and have no idea they are being clocked.

Did you try out any POP shots? I know POP gets significantly less accurate with increasing distance. It would be interesting to get a POP reading at >3/4 mile and then switch to C/O and see how far off it was.

The MPH Bee III is a "loud" Ka gun. Yoda had posted somewhere that they boosted its output or some other technical thingamajig that made the Bee much "louder" than Stalker 34.7 or Kustom 35.5. Enjoy the new gun....it does have POP so that would be a hoot to play around with.

The speed limit is 35 mph. There are
lots of cops that come around here for two reasons. There is a cemetery for law enforcement immediately to the left in the video just after the first road to the left (facing south). In 2015 there was a hugely publicized funeral service for a Utah Highway Patrol officer that was gunned down as he stopped a vehicle. Every agency in the state sent as many units as they could spare to the funeral to participate in the formal funeral procession. Working right there, I just walked out our building and went and stood on the sidewalk as the procession came in. You should have seen all the unmarked vehicles I saw there with their lights flashing in show of support as they came. It was a good opportunity for me to make some mental notes of the various unmarked to watch out for. Beyond the typical marked and unmarked Fords, Chevys and Dodges, they have unmarked Toyota Siennas, Toyota Camrys, chargers with 22 inch rims tricked, pickup trucks with covered toppers, Chevy Camaro’s, and Ford Mustangs. I’m sure there are others I’m leaving out, but I think we have a higher percentage here of unmarked vehicles that are not your average unmarked vehicle.


Additionally, that road immediately to the left leads to the local police gun range that all the different cities in the county use to go and practice shooting once every two weeks. Not just municipal PD, but county sheriffs, Homeland Security’s local office, and the FBI too. So I literally pass all sorts of marked and unmarked law enforcement every day on my way to and from work. I work at a building that is directly across from the cemetery and public park (which is reserved to become cemetery property as the cemetery grows. The good in all of this is that I get to become familiar with all the unmarked cars in the area as I’ll drive past them when they’re pulling in or out of the road that leads to the gun range.

The other positive is that the majority of the time (but not always) that I pass a cop on this road, they usually aren’t patrolling and are just on their way to the range and back or shortcutting through to bypass the bigger busier streets.

I have played with POP on my other MPH Speedgun Pro, which is like the Bee III but both handheld and dash mount capable with a backlit LCD touchscreen. POP works pretty well as long as there aren’t too many cars around. If I was in a 3 x 3 lane city road with cars near by on all sides of me it was pretty useless. It worked best when I had lots of space in front of me and used it to measure cars coming at me on a 1 x 1 road, where the car approaching me also had a gap in front of it.

That’s interesting that the power for the MPH BEE III is higher than the rest. Do you know if that is for all MPH units like the Speedgun Pro, or only the BEE III? I’m curious to see what other Ka band units can read this far off.

In the near future I hope to get a GoPro with a suction cup mount that I can use to film testing. I don’t have the most steady hands and that definitely shows in the video. Maybe Santa will be good to me this year. :)

That would be a cool stretch of road to shoot some lidar on too!

Interesting information that corresponds to TXCTG's experience when we had @Vortex's Bee III for some testing in Waco way back when. We ran out of course that day, even though we moved the source a about a mile farther back than usual... lol.

the longest off axis hit in heavy terrain was 33.8
would be nice to see another pop range test w/ R3.

Does pop work in moving mode too?

I saw a BEE III on eBay for about $400 bucks a month ago. You get it?

I got a Genesis II 35.5 back in April or May. I have played and tested and know it’s weaknesses which is same lane tracking.

Yes, it would be. I'll have to play with that too. Problem would be capturing via the view finder. I suppose I could just shoot near by the camera, then show the view finder to the camera after measuring -- keeping the camera mounted and focused down the road the whole time. That way the video shows the car the entire time and you'd hear the audible sounds of the LIDAR gun, then see the measurements after in a continuous video.

Someone else must have gotten that BEE III for $400, as I paid about twice that.

POP does work in moving mode, but traffic must be relatively light. IE if I'm on a 12 lane freeway (6 lanes in each direction), it's basically worthless when I have cars all around. It works best in moving mode when cars are spaced out a bit. It can't be rush hour packed roads. I'm hoping eventually to get a GoPro Hero 6+ for myself for Christmas. Then I would like to make some good demonstration videos including that.

I need to find some local RD users here that'd love to geek out. Right now I don't have anyone to help me with a second vehicle, so it's a bit difficult. I'll see what I can do on my own, and of course take advantage of any opportunities I get with friends. For a perspective of my situation, the person closest to me physically and in day to day interactions -- My only coworker who has an RD -- he has an older Escort 8500 X50 and thinks I'm pretty ridiculous for buying RADAR and LIDAR measuring devices. So that's where I'm at right now haha.

It would also be interesting to see what strength each RD was showing when being hit from .9 miles away.
Wonder if they would all be at full tilt in this particular scenario?

I imagine most detectors would alert immediately to this "line of sight radar source" rather easily. This would be a strong signal source on top of a hill from 1 mile away.

You are in a militarily advantages position- the high ground - taking pot shots at the cars below. :mmmhmm::mmmsmug:

I believe @Jag42 did a test similar to this a year or so back with a ton of different detectors. Even the low end ones.
