Okay so I got to test my 9500i today. Note:My 2 previous detectors wouldnt alert until I was right up on this trap (v995,cobra xrs 9330)
My 9500i gave me 4 bursts KA band about .4 miles away. Im pretty sure this was instant on. But it gave me enough time to slow down if i needed to. lol and my passenger was like "You can pick them up that far away?!??". But anyways these are my local PD that setup up a speed trap for this school zone.
