my local town police cops run alot of Ka 35.5 freq. kustom signal radar units. and most of all other's run stalker dual units 37.7 KA band and motor cycle cops run stalker dual KA band all of them but most of them also have handheld kustom signal talon Ka radar gun. a few laser guns also stalker units most of them but also other models.one local cop that i know of runs a beeIII ka pop unit.and also 1 cops that i know run's a k band PoP Gun so pretty much that is all i have seen. I have never seen X band in my town or oklahoma city the only thing i have seen is vascar bye small aircraft plan OHP in the highway but that is rare atleast for me but be safe cause vascar does happen.
