I am hoping folks here will help me decide what radar detector I should buy to protect me on frequent long drives the length of the Mass Pike, 495 and Rt 3. So, that means detecting the equipment used by the MASP. I use Waze and that has been helpful. I am diligent about reporting my sightings on the app. I have a whistler XTR 140 but it gives me so many false alerts I stopped using it. I am leaning toward the Uniden DFR9. I really don't want to drop more than $250 if I can help it. I'm having to drive the Pike, 128 and Rt 3 more and more at night so I really need something when Waze reports and visibility is at its worst. Any help or advice you all can provide will be greatly appreciated. I have been relying on Waze and my eyes for 2 years and know I am running on borrowed time!
