Got my brand new MPH Z35 unit today....... Tested POP on the 9500i from 750ft (measured with Laser Atlanta) traveling at 40mph on a flat, straight 2-lane road with ZERO traffic. With POP mode OFF it missed every single POP shot (approx 20). With POP mode ON it reported POP 1 time and had zero other alerts (roughly 25 times).
Quick trigger time....... 9500i silent and the Z35 reporting the speed every time (20-25 times). Pop mode ON and OFF, it didn't matter. ZERO alerts.
We took my Saab out to 3500FT and traveled toward the Z35 at 30mph and I did about 10 quick triggers.....NOTHING.
