I always believe whistlers top models get the short end of the stick they either dont get tested or they just assume whistler and cobra are pretty much the same. It be nice one of these days to see either the XTR or Pro 73 get a fair testing. I believe if the testing was done correctly and as real world as possible it would produce some suprising results that would lift some eyes. The newer whistler rd's is not a bargain base style rd by any means. And shoudn't be treated that way. That is what cobra should be reserved for bargain base.
