It's pretty old... I'd rather go for a new unit instead. But if all ya got is a twenty it isn't bad.

No! Those earlier Ka Superwide BEL models sucked. False all the time and poor range on Ka band. While the falsing may cause him to drive slower, eventually he will ignore the false alerts because they are so frequent.

You are much better off with a newer BEL. Go with one of the 900 series for better results.
