I just recieved a brand new V1 with POP last week as my old unit(1997) was stolen.
The new MPH Z35 radar ups the ante. My V1 might need to be upgraded soon.

Couple of things that work againist the Z35:
-Z35 is used stationary only, cannot be moving.
-Z35 Hand held, the likelihood of a cruiser stopped along side of the road in the same direction of travel is rare.
-Z35 does not use DSP that previous generation radar uses which can select which lane they want to montior.
-Z35 only tracks the strongest or largest target(trucks show up over cars)
-No information if Z35 POP can be used to measure traffic in both directions as the officer sits.
tomm, POP is K or Ka. There is no difference in the frequency which will make it detectable in the future if it is not currently. Supposedly to make newer POP detectable, more false signals will be detected by a detector. If thebigjoeshow can beat regular radar on the street or in court he has no threat of POP. POP does not use a computer to track a history of sample readings used to verify a "locked on" speed. Rocky Mountain Radar uses the same prinicple in their jammers. They are not actually jamming the radar, but confusing the computer sampling and not allowing a locked on speed. Ask me how I know! An officer maybe able to turn off the computer sampling or listen to the doppler frequency while the radar is being used and a detector will be recieving the signal the whole time.
When caught sleeping at the wheel I have ask for a locked on speed when stopped, the officer gives some excuse that I seen you flying faster than surrounding traffic or the nose of your car dived('99 Regal GS - read soft suspension) and they say your using a detector as they look into your car. If it is local I will go to court to at least drop the points.
Which leads me to the question of why twice, once in Indiana and once in Michigan recently, my V1 picked up two(2) sources when being zapped by an oncoming officer? Maybe be POP?
