I have had 3 close calls with the Virginia State Police lately all on 35.5 so wanted to get some insights from the group.

The first one daze indicated police ahead at just about the same time I got an alert. It went from zero to 10 in no time. I was not going that much above PSL so not big deal but if I had been I would have been owned.

Two other incidents where I feel that on 35.5 the performance is not that great. I have used radar detectors for over 20 years so its not like I expect miles of warning but I am starting to feel uncomfortable. I know the Pro-M is not an R3 or 7 but I kind of feel a litle disapointed in the performance lately. All three had the cop facing me. Could they have all been using IO yes so that is a consideration but I would think I might have got a sniff before being in the kills zone but not in all three cases. Terain yes it could have played a part in one maybe two but the third was a strait shot on pretty level ground.

I have the RD mounted to the left of my RVM up high on the windscreen. I drive a 2018 GMC Sierra. The only settings I have changed was to lower the speed limits for auto city. Latest firmware installed.

I love the BSM filtering over my RL-O howerver and if they are using RDDs they are not finding me so thats a check in the win colimn.

What do you guys think.

Virginia frequently uses 35.5 I/O and if they are being selective and the terrain is tricky then you are not guaranteed an alert ahead of time. That is the risk you take if speeding. The first scenario you describe sounds like I/O for sure.

Pro M has good range and is undetectable by RDDs so I think it is quite a good choice for your area. It's possible you have a defective unit but I think it's unlikely based on what I've read. If you continue having encounters you think point to a defect in your unit, try posting videos of the encounters here to the forum and the members can help you judge whether there's a problem.

The Pro M is pretty average on 35.5. Slightly better than the Max 360. Slightly worse than the V1. Considerably behind the R series in the hardest terrain and vegetation conditions.

If I was you and you still have your Redline-O I would make sure you have RDR off, which I know that you do and mount it on the windshield with the Pro-M just for the hell of it. The Redline-O is a monster against 35.5! I have 3 of them and they can go toe to toe with my R1's and even beat them! At least you'll know how your Pro-M stacks up and if you have a problem with it or not. I'd mount them as far apart as possible and let them eat! I've never ran a Pro-M but my Redline's play great with my R1's with no problems, like I said it's just for testing purposes. If anything, the Pro-M might affect the Redline but I doubt it. As soon as you get shot with 35.5, you'll know what time it is! Even against forward facing 35.5. There is nothing worse on Earth than 35.5 I/O! I've been facing it for years and it sucks! I ran my V1 for years and started having lots of close calls against it, even with Ka guard off! My R1/Redline-O ghetto setups are killing it for me now getting even the smallest whiffs of 35.5 I/O even from off axis and over hills from the front and back!

Doesn't rdr-off just mean it doesn't detect other radar detectors or maybe it's rdr-on that doesn't pick up other detectors?

I'd still turn K Off on the Redline-O. I think (only speculation) that there is more likelihood of interference on K-band.

Yea I frequently pass Tennessee highway and sometimes I get alerted LOS with my R7. I wouldn't call off the ProM just for that. Just shows that you need a rabbit if you are gonna speed.

It's kind of tough to tell if something is going on without being able to see it ourselves. I can say that I rarely see more than 0.5 miles from my R3 up here in 35.5 land. It's a combination of terrain, foliage, heavy traffic, and dense surrounding area. All of that can seriously effect range, especially against 35.5.

I wouldn't write off your Pro M just yet. Keep playing with it and if you have a dash cam, post up the videos! It would help for us to be able to see what you see :)

I would also seg the Redline to 2-5-8 to make it as killer as possible, I left that part out! Of course I'd also turn X-band off as well.

Honest opinion and no offense...I think you are;

1. Looking for reasons to find fault with the ProM
2. Assuming the problem is range or sensitivity related to make the R3/R7 look better.

There are at least three explanations for lack of warning;
1. Terrain
2. IO
3. ProM 35.5 performance
  • Only you know what the terrain was.
  • Only the LEO knows;
    • If it was IO
    • If they were shooting every vehicle in front of you.
    • If they were shooting vehicles which appeared to be speeding.
    • Were shooting at you when the ProM alerted.
Many of us do a lot of research before paying several hundred dollars for an RD, so we know the devices strengths and weaknesses relative to the other devices. As a result, when we get caught, or almost caught, we jump to the conclusion it must be because of weakness(es) of the device we bought and we conveniently do not think of the times we were saved because of the devices strengths.

Every 'old paradigm' RD, dare I use the 'L' word, is a compromise.

If the area you drive the most has difficult terrain and lots of 35.5/IO, you might have bought the wrong RD for your environment.

As Brainstorm69 mentioned, the ProM 35.5 performance suffers in comparison to the R3 and R7 in such conditions. However, complaining about it would be like complaining your 2018 GMC Sierra quarter mile performance is not that great when compared to a Camaro. Learn to appreciate the strengths and compensate for the weaknesses. If your requirements change, find a RD that better meets them, knowing there is no perfect RD.

No offense taken and no not looking to find fault with the Pro-M. Like I stated I have had a RD in my car for pretty much as long as I have had a drivers license, going back to the X&K only days.

I completely understand all the factors that go into reception from frequency, transmit power, terrain, I/O, C/O, angle to the radar gun, traffic and sometimes even weather.

As with every purchase I make I try to balance all factors in order to make a good decision. RDD immunity was a big factor in my decision because I live and drive 99% of the time in Virginia. BSM filtering was another factor. Right out of the box the Pro-M gets high marks in those two key categories.

I looked at all the tests on the forum as another data point and the Pro-M was neither top nor bottom but like @Vortex said "a serious contender". In most tests it seemed like it gave plenty of warning before the kill zone. No one test proves anything but thanks to the hard work of many of the members here there was ample test data to review from all parts of the country and all kinds of radar guns.

I also like Radenso as a company. They are enthusiasts like us and really seem to be working hard to put out great products, support their products and keep us in the loop on the new stuff.

All that being said my post was not to be a criticism of the Pro-M. I completely understand there are trade-offs with everything so it was more of a conversation starter to get the thoughts of others here that might have similar experiences.

If you do run both at once to test, you might just segment the Redline to 8 so it focuses on 35.5. It could give it an advantage but what you’re looking for is to find out what method is being used. If you are almost on top of them and both are pretty close before alert you know. If one is going off well before the other you have more info to go on. I’m suggesting testing to see if its the Radenso that needs to be looked at or if its just terrain and method being used.

When I see an SUV sitting in the turn lane near a median and no signal I pretty well know what I’m looking at. I had my doubts for a minute today though since I could almost see his face before I got an alert. After passing him, it was rear I/O. He was waiting for people coming down a hill around a corner and what I picked up as I got to him was reflection from that. Never see that here, you see C/O pretty much all the time. I hope they were just trying something new and moving on but I will have to watch for that now. I’m using an R7 and they use 34.7 here so I had lots of opportunity but it was not available today. I drove PSL until I could verify what I was looking at. Good thing I did.

The testing several RDFers conduct, multiple RDs on the same course (terrain) against the same threats are invaluable because their testing methodology reduces the variables to one, the RD. However, I've never put much value on others individual experience, even with the same RD I've had, except for determining if the RD I had was defective. If the other persons terrain is not the same as mine and the threat(s) are not the same as mine, comparisons, for me, were interesting but of limited vlaue.

I have gotten some pretty good, like 20+ saves just letting off on my Pro M. Saves Mrs. Leadfoot on the reg. Still, 35.5 is one place I would really like the Pro M to do better. I drive tough terrain, some 35.5 alerts for me are serious close calls with my Pro M. If you are comparing the range with any of the big R names above then the 35.5 performance is not as great. I have close calls with my other favorite detectors, it happens. Just less with them.

One great thing about Radenso, they seem pretty top notch with customer focus. I am pretty happy with my Pro M, it is a pretty cool little unit, I would just probably contact them if I had any problems.

In routine street work, I would suggest M has less range as 360 series On 35.5. Except off axis M makes up ground.

There is nothing like owning your own Radar Guns for cases like this! I have a Genesis 2 setup with a 35.5 Ka gun and a 24.150 K band gun. I have a lot of detectors and have taken them out on several different courses that we have set up to separate the men from the boys! As long as you test them on the same day under the same conditions without moving the guns you will be golden! This is how I found out just how much off axis hurts even my red hot 3.872 V1 against 35.5! Even with Ka guard off! It kills it on our long distance straight course, but at our off axis course my range drops like a rock! My Redline-O's and R1's kill it at both courses. Without being able to do my own tests, I never would have believed how how much difference there is between the detectors! If you face 35.5 I/O even a little, I would make damn sure you don't have a problem detecting it or it won't work out well for you!

I'm just basing my comments on prior testing TXCTG has done. You may be right about off-axis vs on-axis. I don't use either enough on an everyday basis to have a good feel for that.

I agree! I haven’t done any testing with my radar guns yet, but I do plan on doing so in the future. It can definitely help when trying to determine if your detector is working properly and how it compares to others especially on off axis detection. 35.5 can often be more challenging to detect (especially off axis).

When I bought my Golden Eagle II, I also bought a separate K-band antenna so that I could have a 35.5 antenna and a K-band antenna all in one unit.

I have had 3 close calls with the Virginia State Police lately all on 35.5 so wanted to get some insights from the group.

The first one daze indicated police ahead at just about the same time I got an alert. It went from zero to 10 in no time. I was not going that much above PSL so not big deal but if I had been I would have been owned.

Two other incidents where I feel that on 35.5 the performance is not that great. I have used radar detectors for over 20 years so its not like I expect miles of warning but I am starting to feel uncomfortable. I know the Pro-M is not an R3 or 7 but I kind of feel a litle disapointed in the performance lately. All three had the cop facing me. Could they have all been using IO yes so that is a consideration but I would think I might have got a sniff before being in the kills zone but not in all three cases. Terain yes it could have played a part in one maybe two but the third was a strait shot on pretty level ground.

I have the RD mounted to the left of my RVM up high on the windscreen. I drive a 2018 GMC Sierra. The only settings I have changed was to lower the speed limits for auto city. Latest firmware installed.

I love the BSM filtering over my RL-O howerver and if they are using RDDs they are not finding me so thats a check in the win colimn.

What do you guys think.
Primarily the main reason as to why I sold my pro-m for my redline ex, was because it did not perform well in this band segment and I received a ticket.

Just a short update. I know I am breaking the cardinal rule of running two detectors on the same windshield but....I have been running my RLO, X and K off while running the Pro-M.

On a trip out to WVA to ski last weekend they both alerted to KA within seconds of each other on the few hits that I had. No constant on sitting where I could get a sense of distance and the difference between the two however. One place that all my detectors false to KA on a back road in WVA they both hit at the same time so nothing there.

Since I have been driving with both detectors I have not had an encounter with VSP running 35.5 which was the whole reason I started this thread in the first place. Kinda like gassing up the snowblower and it never snows. Not that I really want to run into 35.5 out there but on the other hand I do. Sometimes I think we are glutens for punishment.

I am heading to Chesapeake VA for business on Thursday. I will take a road that I know the VSP like to camp out on and let you know what I get and post any updates or observations I have.
