Well I got an itch to try a better detector today and went out and purchased the X50 red version 5. Since there are no known speed trap areas around me I tested it as best I could at areas where I get lots of falses and already know the bands of the door openers. All I can say is that K band sensitivity is twice that of my previous Cobra XRS 9500. I discovered two new K band door openers on roads I have been driving every day for the past 6 months with my old detector that never flinched at them. I will be taking a 7 hour trip down to Florida next week and should be able to fully put it through its paces and test Ka band sensitivity which is rampant down there. I have been playing with the settings and am already very impressed with the adjustability of the unit. I have heard nothing but complaints about the RX65 and its self calibration error messages and was previously sold on the V1. I opted to try the X50 which gets great reviews from the members on this board and figured if I was disappointed I will return it and become a V1 Zombie. I will give you guys a synopsis of my trip and how the detector performed once I get back.
