This is wrong. When talking about distances vs sensitivity (in dB - logarithmic), it is the difference in distance that counts, NOT the ratio. This is because the signal is is relative to the distance squared.
Therefore, it is expected that (in ideal conditions) the DIFFERENCE in distances with / without foam be the same. NOT THE RATIO.

I think you are misunderstanding what we are trying to say here.

When we mention ratios, we're not talking about distances vs sensitivity in dBm, none of our results are in dBm. We're talking about one detector's distance vs another detector's distance in the results..

So for example, let's say that Detector A gets 500 feet of range in the eccosorb test, and Detector B gets 1000 feet (500 feet better, but also double the distance). If the same two detectors are tested on a long course, and if Detector A gets 5 miles range, then one would expect detector B to get 10 miles of range (not 5 miles + 500 feet).

To relate to sensitivity in dBm: in this example, of course Detector B is obviously 6dB more sensitive than Detector A, and should get double the range of Detector A (in bore-sight test conditions of course), and the ratio between the distances of the two detectors always stays the same.

In this respect, the ratio between the detectors is what matters.

Are there any plans to have Michael B test the Vector 940?

---

All of the detectors that we used for the tests were sent to him for lab sensitivity testing but for whatever reason he chose not to supply us with DB numbers just order of sensitivity :cry:

---

Interesting....
where can I find the order of sensitivity? I looked but I could not find it.

---

not posted[

Where did the V940 rank in the order of sensitivity?

We do want to thank Mike B. for his contributions

LMAO!!!!!!!!!!!!! TheStaton you crack me up with your sense of humor comments. :oops: :lol: :lol: :lol: :lol: :oops:

Was the brand new retail X50 a Rev 6.3?

I don't think we ever reset it to find out. We'll get RacerX to check.

GOL, what was the angle of the car or antenna with the forward facing test?

I had my red trans / am pointed at an angle to the road. then when I mounted the antenna I made sure it pointed pretty straight down the road.

it was about as real world as I could get it. I didn't want to point the radar directly down the road, being most encounters I've ran into the officers have been setting off on a ramp with a small angle.

here's a couple of pics that show it a little better. look down at my windshield on the drivers side and you'll see the 35.5 antenna.

Those pics really help to show the angle. The one on the bottom and in the GOL site picture taken from behind somewhat was tricky to look at when thinking about the angle. That clarifies it thestaton and a nice looking ride you got there too. :wink:

Veeeeery impressive Guys! 8) :D

As-always, as a truly independent hobbyist - one of the "small guys" - a big THANK YOU. :)

Oh believe me It's not hard considering the detector comes from escort :wink: A company that Produces the STi with huge manufacturer variances

Thank God Rob that someone finally brought this point out.

No one ever looks at a statistical point of view (although I have many times in the past if you remember). A few samples does not say anything about the population. Why does V1 have such a great reputation? Well, ask virtually anyone who owns a V1 and look at anything on this forum and any GOL testing, the V1 always performs like a champ at the top of its game.

However, detectors like the STI and 9500i have had so many issues. Some STI were supposedly bad on 34.7 in addition to the 33.8 issue (yet others in the GOL tests shined like stars on 34.7).

People often base assumptions on small samples (a few detectors out of tens of thousands.)

There is really no way to prove that any one detector is "the best" in any category unless you used a huge sample (this gives us reasonable assurance the sample is representative of the population).

A few hot 9500i does not mean much when you care comparing them versus thousands of Valenttine 1's that have a proven record of performance (although they also have had issues).

The same goes for hte LPP. The LPP seems to give consistent results no matter who tests it, no matter who shoots at it, and no matter who you talk to.

Manufacturing variance is a common theme in production. Try taking a business stats class and you will see.

Heck, someone even stated recently that their V1 was within the production standard variances according to Mike the Tech. All companies that produce a legit product develop such standards and reject any product that falls outside of the acceptable variance.

It is therefore reasonable to assume that some products will be"hotter" than others.

A bolt from the same production line can have different tensile strengths from its cousin that was produced three bolts before it. As i stated in my previous post, the 9500i seems to be coming up. But, as Rob said, let's not forget about the mfg variances that belscort is famous for.........
