I have been driving with my GX65 for several days and I'll have to say it is a very quite detector...I get next to none of the falses I got with my 9500i such as CVS, Walmart and so forth. I have not had to use the Truelock yet because of very little falses. I do get great detection on K band when it is a actuall LEO. I have not had a KA encounter yet but if it is anything like K band it will be great...It is so quite that I worry it isnt working so I drive to some local K band signs just to test it...I love the voice...Its crystal clear!!! I'll post more as I get more encounters.
