stalkervision,
I too have grown quite fond of both BEL's tech display and Escort's spec display (which does the same thing).
Historically, since I live in PA and routinely drive in NJ, having the capability to know the exact police radar reception frequency was unnecessary as K (24.1 Ghz) and X (10.5 Ghz) ruled the day. But as Ka is becoming more prevalent in NJ as the older K-55 X-band guns get replaced, having that additional information is proving very valuable, indeed!
Once you get used to seeing the different Ka frequencies, you can feel a little naked and exposed when you don't have that additional intel! I believe it's easily as valuable information as [the V1's] directional information [without it].
