Well i have had my 9500ci for a few weeks and tested it for interference with my 9500ix and came to the conclusion there isn’t any interference under almost all circumstances.
I was also starting to think i bought this wonderful 9500ci so i could here 100x more falses to X band and K band for an additional 5 seconds of real sensitivity.
But last night i was driving on my regular back curvy roads to my GF house when i got a very week K alert that’s never there (nothing from the ix initially). About 10 seconds later as i came around the 3rd bend in the road my ix went full blast and about a second later i see a LEO tucked into some trees and shrubs.
Though it would have been very close with my 9500ix, i was extremely pleased how well the CI did with such a difficult encounter. It seems the 9500ci with difficult scenarios is really where it shines.
Over all i would say the 9500ci alerted a good 1/2mi with 3 bends in the road with relatively good ramp up so i knew just before i was within sight distance of the LEO.
