So I've been getting really antsy to get some testing done and finally had some time yesterday. First let me get one disclaimer out of the way. This was a course of convienence as I was by myself and didn't have a lot of options, thus, it was a bit terrain limited in Direction 1 which is going from West to East. That being said, I made a lot of runs and the data tells me quite a bit.

First, the detectors:

R1 FW 1.37
Seg 2,5,6,8
K Narrow
R3 FW 1.48
Seg 2,5,6,8
K Narrow
R7 FW 122.123.111
Seg 2,5,6,8
K Narrow

Next, the guns:
Kustom Golden Eagle:
Antenna 1 Tuned to 35.5
Antenna 2 Tuned to 34.7

Decatur Genesis 1
K band 24.150

I made 3 runs in each direction for everything except the R1 and R3 on K as I could see what was going to happen and I was running out of time since a creepy dude kept staring at me every time I went by.

The course:

When traveling in direction 1, West to East (Labeled D1) there is an opportunity to alert but not all detectors did on all settings. The second alert opportunity traveling in the same direction is about 500 feet before the Kill Zone All detectors alerted somewhere in that area. As you pass the Radar Gun I record the "last sniff" for that run and direction before turning around further down the road and going in Direction 2. All Detectors will have a first and last alert in direction 2. Of course the R7 has a big advantage for the last alert since it has a rear horn. I thought I may as well collect the data though as it's worth a comparison.


Here's the Bulk Data:
34.7
116538

On 34.7, both my R1 and my R7 were able to sniff out the early alert but my R3 wasn't able to detect it. I think this has more to do with detector variation than FW though. Also, remember that this is a detuned 35.5 antenna and not a gun that originally came in 34.7. What's interesting about that though is the below.......

35.5
116539

So on 35.5 only the R7 was able to catch a whiff at the first alert opportunity. What I find really neat about this test is that since I'm using a de-tuned antenna, and aimed it as similarly as I could to the 34.7 antenna, what we should be seeing here is the frequency difference only, and not a difference caused by the output of different gun models. In any case, I face 35.5 most of the time in terrain exactly like this so I'm happy to see the results here.

K band
116540

So on K band I did full runs TSF on and TSF off for the R7 and you can see that there is a penalty for TSF for the R7 on this particular course. I don't think it's by much, but it's enough that it would alert every time at the first alert opportunity with TSF off but never alerted in with TSF ON. I doubt that the penalty is "linear" in that you won't lose a set distance, instead I think that the weaker the signal, the greater the penalty. As you see at the second alert opportunity, there's little difference. More testing in this area has to be done. In any case, the R7 still beat the pants off of my R1 and R3 on K band; even with TSF On. As I mentioned earlier, I only had time for limited runs with the R1 and R3 on K band

Here is the average data for all runs and detectors:

I have all runs on video but my internet sucks so I'm only going to upload a couple. If anyone wants a specific run for whatever reason, let me know.

R7 34.7 Direction 1 Run 1

R7 34.7 Direction 2 Run 1

NSFW
These buttnuggets actually caused a reflection to mess up my testing on one of the runs and I had to do it over.

It's the middle of the day! No respect!
I had to dodge a few turkeys as well.

The biggest reason I wanted to do this testing was to prove to myself that I could trust my R7. So far it looks really good to me. It's as good or better than my other 2 R series detectors AND it has arrows, which transition VERY nicely. It seems like they may have done some work on the arrow transition as part of the last update. With prior encounters they were a bit slow to transition but now they seem to go quite quickly.

Here's an arrow transition example:

That's quite the number of runs and number crunching to deliver the results.

What did you end up using for calculating distance?

Yeah, it took me HOURS. I figured I had the runs on the camera and used a half a tank of gas so I might as well do the number crunching.

I used the GPS coordinates from my dashcam, the gun coordinates, and math. LOL I should be +/- about 30 feet based on my chosen speed of 45 MPH and being very careful about which GPS update the alert was closer to. Doing 3 runs each should bring down the error even more.

Code:
=6371*ACOS(COS(RADIANS(90-I2))*COS(RADIANS(90-$I$136))+SIN(RADIANS(90-I2))*SIN(RADIANS(90-$I$136))*COS(RADIANS(J2-$J$136)))/1.609
That's the Excel formula. Take it times 5,280 for feet.

Amazing work especially since you were all by yourself! Kudos! Looks like the R7 will be taking up some real-estate on your windshield.

When we did our testing this guy kept trying to hail us down and making "wtf are you up to" gestures. We just waved and he eventually went away. Another guy pretended to take photos of us, we just ignored him.

Cool stuff. The R7 has definitely done well for sure.

Good work! Nice to see the comparisons - also noted, you didnt mark the "creepy guy" on the map.

Great job! Interesting presentation of results. I'm going to need to study it better when I have more time.

Translation: "This must only make sense to OBeer".
LOL.

It's a little schizophrenic with the naming conventions that's for sure. I kept refining the data so I could make the charts so in the top charts just look at the description on the left. Any time you see "First Sniff", "Second Sniff" or "Third sniff" it's the front horn and anytime you see "Last Sniff" it's the rear horn.

The last table is basically the TLDR for everyone.

AVG D1 A1 = Average Distance Direction 1 Alert Position 1
AVG D1 A2 = Average Distance Direction 1 Alert Position 2
AVG D1 Rear = Average Distance Direction 1 Rear Horn
AVG D2 A1 = Average Distance Direction 2 Alert 1
AVG D2 Rear = Average Distance Direction 2 Rear Horn


Hopefully that makes it less confusing for everyone.

Nope. lol. It's just a different way to present results that I need to look at more closely. You've good lots of great data there. And I've been try to think a bit of different ways to present data lately. You could be onto something! ;)
