To some the arrows are a "curiosity" however I disagree. The other day I turned left at a light and a statey followed me up a hill, the detector howling with the arrow showing to the rear. As we progressed, the arrow showed to the front and the number 2 came up, both in the none X band. Sure enough coming toward me was a NYS Sheriff with his radar blasting. The thing is very sensitive and I get signals as much as a mile ahead of time, plenty to brake down and look "not guilty", if you get my meaning. Best detector I ever had and had an older Passport in my van until it broke and the techno at Passport said it was too old to update or repair.
