After 2 months reading and learning i pulled the trigger on a Whistler PRO78SE. Due to some financial shortcomings ( my wife just lost her job) i had to settle for the best one for around $150. I installed it right away moved it to city 2 filter 2 and went to a speed sign i knew. Sign was not reading speed anymore but was changed to info mode. So no luck with the detection. I decided to go to a strip mall and test the city mode. Boy this detector can detect the automatic doors big time. I disabled X so i got K reading. Not sure if it was mixed X to K or the doors were K signal. I think i will use auto quite mode in city. On the main street it barely picked up any doors so so far so good. I purchased it for a trip i will be taking in February. I do my city driving 90% in rush hour so i can not speed so that was not why i bought it. I bought it mostly for highway use as i tend to keep 20mph over PSL. Down here the traffic flows with 15-20 mph over the PSL. This is my first detector since 1995 BEL that i am not sure what model it was. Now i need to find a bracket to mount it under the mirror. Will post more when i get some encounters with Radar.
