ahh gotcha. so you think sticking to a NZ DFR7 would be better than bringing one in (aside from the cost savings)? will DFR7 go down that low on K band?

Not quite sure we're talking about the same thing...

I have tested different detectors and setup:

So far the R7 is definitely superior to the DFR7 (NZ or US). This is because the R7 combines excellent redflex detection and massive Ka band detection.

The US DFR7 I tested was able to detect low frequency K band redflex. However, I never used Ka band detection on the DFR7. [This is because in my tests I wanted to see if I could run two detectors together. I was very successfully demonstrating a combo with the R3 and DFR7. So the R3 was giving massive Ka band detection similtaneous with good redflex detection through a US DFR7. - see my earlier videos on this thread]

However, the DFR7 at its current price on ebay/amazon is a fantastic detector, and can be installed with my updated NZ gps database. The DFR7 NZ does have better firmware than one from the US. However, would I pay the massive overprice on the DFR7NZ just for that firmware? No, not a chance.

=> My recommendation for a Uniden to run here is either an R7 or a DFR7, where you choose to buy it from is up to you.

This footage is captured using a US R7, not a DFR7. Had I had a bit more time, I would have liked to compare redflex detection range against the R7 and DFR7. I had the DFR7 with me at the time, just needed to get back home. Redflex is still tough. This instance possibly got better range because the approach on the road bends through the radar beam at distance where it was first detected. However, the R7 does keep hold of the signal so, still looks like a strong detection. This run really would have been the ultimate site comparison to compare different detectors against redflex. No other radar interference; and not too much traffic so I rule out 'lucky' reflections between one run and another.

This signal was also low K band at about 24.034 so completely undetectable with the R3!

I have had two very useful Ka band detections on the vertical mount R7. My gut feeling is my vertical mount is possibly not quite as good a range as my previous standard mount R3. However, its still pretty close, and more than adequate. I had a good instance yesterday, just haven't downloaded the footage from the camera.

Basically in a built up area, I was on the approach to turn right in the dark when I got a 'front' alert. I decided to wait at the junction, sure enough about a minute later the police car came around the corner. So I really am loving the R7 so far.

My only criticism is to find a better vertical mount. First one I made from Aluminium, and works well but the suction cup ends up above the detector and takes up too much space cutting down visibility. Currently I am using a wizgear magnetic mount. This is quite a large mount that goes on the side. However, the metal plate now keeps coming unstuck from the R7. So either need to find better adhesive, or make another metal mount to clip into the R7 and sticks to the windscreen from the far side of the detector to give maximum visibility.
I got some extra strength 3M double sided tape from Mitre 10. It's the black stuff, not the grey.

looks like i can get a DRF7 landed for NZ$300! wohoo! is it difficult to install your GPS database? Really appreciate your advice and help

For the benefit of others I am running a US DFR7 up here in the Waikato. I haven't done enough driving since I got it, and as such haven't actually come across a redflex van yet.
That said, I have had a false on 24.03 so that suggests it can go lower than the published 24.05 specification.

Re Ka, I get fantastic warning on Ka, the DFR7 gives me ample warning (even over the brow of hills), on a straight I would estimate I can get 2km of warning (or more) of an oncoming police car broadcasting Ka band.

I have tested against reflex fixed camera's also, I probably get ~300m warning approaching the camera from the front. From the back however, it's lucky to give any warning, so you have to talk nicely with Mithheru about giving you a US compatible copy of the NZ GPS database. :)
