It's my impression that many, most, or all of these various radar detector tests do not perform rear-sensitivity or distance tests where a LEO is driving up from behind you with moving radar and your detector is facing ahead of you. The Valentine is (I think) good for this because it has a rear-facing antenna horn, but maybe it's the only one that does (?).
I'd love to see some testing like this, and even more:
I usually keep my RD down on the center console instead of up on the dash or the windshield (naturally this is done because I don't want it to be seen and it's easier to turn off if I see a LEO). I'd like to know what effect that position has on being detected by spectre, as well as IF I had an STI sitting in that position how would it affect it's ability to detect LEO from behind?
In general how good is spectre at detecting RD's if LEO is behind you vs in front of you (ie facing you) ?
