It was 41°F and was raining in the morning. The course was 1.3 miles long. By the time everyone showed up, it was time for lunch, so we ate and the started testing, the rain had stopped but it was still overcast.

The video doesn't do the course justice, especially on this first hill. From the radar vehicle to the top of the first hill was 870 ft.

Now for the data!

Max elevation: 213 m (699 ft)
Min elevation: 159 m (523 ft)
Elevation gain: 31 m (102 ft)
Max grade: 17 %
Min grade: -2 %

In previous years where we did off axis testing, we were getting around a mile detection. With the elevation change and horizontal antenna, we were in eye sight of the gun but by then, speed was acquired as we came over the hill. So if you driving fast on a hilly road, your reaction time might not be good enough to scrub off enough speed before you get caught and since the Falcon HR is a handheld radar gun, you are going to get I/O'ed (instant on) and you won't know it is there unless the operator is sloppy.

The Max2 was the only radar detector to detection 34.7 the entire length both from the front and the rear! It still had 2 bars on the detection by the end of the course, so we could not find out how far the Max2 could go.

One weird thing we found out was the STi-R Plus does better against 33.8 and 35.5 upside down but it does better right-side up against 34.7 and K band.

I want to thank @lugnuts for checking out the area before hand and @PointerCone, @darkpenguin, @CobawLT2010, @Tallyho, and @GTO_04 for coming out and testing.

Looks good, thanks for testing.

What charting software did you guys use, btw...?

Excellent testing! Thanks very much! Interesting results! Quick question, did you guys manage to test the V1C against 35.5?

some points to note: 1. This is a tough course and the elevation changes as stated can IO any of the units if the operator is good. 2 the orange line means in all cases except for the O that the RD and vehicle were heading away from the source as if you were getting tagged in the rear. The O was mounted on the back of vehicle facing rear so that's why it did well going away from source because it was actually facing the source as it went away from it. 3. Except for the O, all units in the blue lines were coming toward the source from the other end of course. Course distances were verified by both TSS measuring and also iOS GPS measuring tape. 4. Only one Max 2 ( mine) was run in this test since that was all that was available. We did not test my RL nor my Max1 this test. The Max2 did very well in this test overall and Protias and mired rove the course with the Max on Auto and it still got 34.7 the whole way around. Color us impressed. All RDs were mounted in same place for each test.

No, Neo aka Tallyho had already left and I didn't want to use my V1C to keep some consistency.

[MENTION=1134]darkpenguin[/MENTION] did the charts, so I'm not sure.

[MENTION=3565]Tallyho[/MENTION] had to leave before we got to it, so unfortunately we did not. It was just after 5 when we finished up and wives were calling people so we just ran out of time. :(

Great testing guys, did you list or record the capture ranges?

This! Sorry guys. Now I wish I had left it for testing purposes and picked it up from PointerCone afterward.

I do have some YaV1 charts to release from my own data which can provide some context and maybe show how the elevation affected detection. You'll see what I mean once you have the graphics in front of you.

Also, and this is just a pipe dream for now, but it made me realize it would be great to have ALL detectors running on a YaV1 equivalent so that we could have software to aggregate this data and provide distance mapping for all RD's rather than just the V1.

How many feet away from the source the target vehicles speed was aquired?
Just as people were cresting the hill, so a little over 900 ft away.

Thank you for the time testing and providing the results, great stuff.

Some of those Max results are astonishing.

The vehicle speed , depending on unit used, would be picked up between 800-1000 feet because the radar unit was at the bottom of a hill facing the hill and the units were coming at it at the crest of the hill. It could pick up vehicle speed as they crested hill. This is one that Mike V considers one iof the toughest courses / scenarios since the hill is blocking the source as your coming at it. The Gen II seemed to be best at picking up the speed earliest followed by the Stalker, Bee3 and the HR.

Both PointerCone and myself were shocked when it dropped the signal just before the 1 mile marker (right before the stop sign) but then picked it right back up. Escort did a really good job with the Max2 against 34.7. I wonder why it didn't do quite so well against the other Ka bands?

Due to the hilly terrain, we could not measure maximum capture range for the test vehicles.

As far as 35.5, I ran my V1C (3.894) against the Decatur and got 1 mile range heading toward the radar. It was not part of the official test results because my GPS/Nav device did not have sufficient resolution so I used my odometer. But 1 mile is pretty good, better than I expected given the terrain. So a nice surprise for my V1C on 35.5 GHz.

I agree, great course set up guys, I have always preferred over the hill test as long as the hill does not completely block the waves. Good Job Guys.

Crazy how the Max2 beats the rear antenna of a V1? That is very hard to believe and further testing on PC's Max2 will need to be in the stew test and other 34.7 tests. Great job guys ! Thanks for your time ! Bummer on the Ka 35.5 vs V1 testing since Ka 35.5 was doubted on the V1. The V1 beat the RL on 34.7 to the source :eek:

One other thing I want to mention, the Passport takes about a minute (or so) to completely boot up. During one run, it was turned on so I started to drive away, but wasn't detecting anything, so I had to stop and go back until it started to alert. That is probably the one complaint I have against it.
