With time running out on my 9500i return period, I decided to run some comparison tests, with only one detector powered at a time, so as to ensure interference between the two detectors could be ruled out.
I drove by the same radar sources (could only find motion sensors and similar falses) with each detector.
X50 rev. 5 vs. 9500i (2207):
X-Band - detection distance same, ramp-up on 9500i gets way up there when I drive relatively close to source, but no even not right next to the store (supermarket by itself).
Here I was satisfied with both detectors.
K-Band - 2 locations tested. One a Kings supermarket (or nearby store) at a small strip mall. Second location a Home Depot with nothing else nearby.
In both cases detection distance was very very similar between the two detectors.
However, when I intentionally drove very close to the source, the 8500 went nuts (full alert) every time.
By contrast, in both locations, the 9500i did not even get close to full alert - it was *much* quieter, despite driving the exact same route each time.
I even repeated the test at HD with each detector, with the same results.
If the 9500i didn't alert at all, then perhaps the result could be further analyzed to see if the detector might in fact be doing a better job of filtering. However, the problem is that it DID alert every time; its signal strength just never properly indicated when I was within feet of the source, so that does NOT appear to be filtering to me.
Unless someone can convince me that this is, or could be, some form of better filtering on the 9500i, I am probably going to switch back to my 8500 X50 rev. 5 and return my 9500i (2207 date code) until the resolve this issue and the ramp-up issue overall.
I'd rather have to press my mute button (on the X50) one more time and know that I am getting excellent indication of distance from source.
I am looking forward to feedback and thoughts on this.
