For detecting photo, the glory days appear to be over.
My V1 picked up photo all day long. Calgary was a great place to have a detector, as all you needed was Ka to detect ghost cars and photo, and you never get false Ka. K and X could be disabled.
Now they are using ultra low power K band photo on the new units. You can identify them by the two black boxes on the roof.
I turned K band back on and drove by one of these. I didn't pick it up until I was even with it, and even then, I got a very weak reading from it. There is so much other K out there you'll just ignore it, and even if you did detect the photo unit, it's too late. Now I have to watch for the boxes on parked vehicles.
I drove back from Moab, UT yesterday. 1800km. The detector was highly useful for that trip, as most of the US is still using some form of Ka or X on the highway patrols. It probably saved us 3 tickets yesterday alone.
