Four RD Test
I decided to test four RD for the fun of it to see how they would compare with each other. Two are my own personal RD and two were borrowed from friends. My RD are the 9500ix and 8500 X50 (refurb w/S7 horn) and the two borrowed RD were a Whistler XTR-690 and Cobra XRS-9430 (12 band). I ran these RD against a known, permanent K band speed sign that is very strong and facing southeast on the Lake Pontchartrain Causeway bridge as you enter into Metairie, LA. This bridge for the most part is flat and straight with the occasional rise for large boats to pass under. <<JAZZY>> and others know this area well and can attest to its location and strength of the K ban radar signal.
This is by no means scientific but I tried to keep the test as consistent and fair as possible. I started the test at 11:14 am. The temperature when I started the test was 88 degrees (as it registered on my car's gauge) and when I completed the test it was 91 degrees at 12:48 pm. Humidity was high, around 80-85%. I ran each detector separately and never together, and all RD were mounted high to either the left or right of my RVM of my car. I made three passes for each RD and to clarify I ran one RD one time, then I changed to next until all four had made an initial pass and continued this until all four had made three passes. I did this so that as the temperature rose no one RD had an unfair advantage. Each RD was set in highway mode with X band and POP turned off (except for the Cobra which did not allow this function).
The test course was started at the second crossover point from Metairie heading towards Mandeville and at this point is 7.5 miles to the K band sign. There is one slight rise in the road between these two points. Traffic was light to mild and I did not run any RD when I saw a large semi that had the potential to block its view.
I currently do not have the capability to video as my Sony is on the blink, so let me preface this thread with, "take these results anyway you want!" I have tried to conduct an honest test and the results are true with NO embellishment of the facts whatsoever! I have nothing to gain from this other than my wife's look towards me as though I have lost my mind
8500 X50: Run 1: 4.2mi Run 2: 4.1mi Run 3: 4.2mi
Whistler: Run 1: 1.2mi Run 2: 1.3mi Run 3: 1.2mi
Escort 9500ix: Run 1: 3.9mi Run 2: 4.0mi Run 3: 3.8mi
Cobra XRS-9430: Run 1: 1.5mi Run 2: 1.3mi Run :1.3mi
The two biggest things that surprised me the most was the fact that my X50 beat my beloved ix (I am sure this is no surprise to Happya$$I really did not expect that at all!
Below are some photos of how the RD's were set up in my vehicle. I do not have a photo of the Cobra (why I do not know, I thought I got a photo of each, but I am human and missed one and I have already given it back so I am not asking for it just for a photo...). You will see some messed up bungee cord that was wrapped up around the Whistler. He has some weird set up that allows him to add this to his motorcycle, but this did not affect the RD at all! You can also see how the Whistler gives my ix a false KA read when they are on together beside each other. The photos are not very good. I should have changed the setting and taken them outside instead of in the apartment garage.
Enjoy, criticize, etc...
