Just got back from Northern Ontario with my 1 week old refurb V1, and I'm in love. I brought along not one but two old "early warning" RDs in case of an encounter with the spectre run by the OPP, so I could cough up one of those if he was confiscating my RD. No such encounter.
What I can tell you is this:
-PA staties are running constant on K-band, as far as I know exclusively. I did not encounter any other bands or instant-on. All falses from speed signs and toll plazas were also K. Since I was on the highway I was in "A" mode and in built up areas did pick up X falses.
-NY staties are running the same. I did not encounter any KA or X or Laser from Police.
-OPP are running K band in Southern Ontario and X and K bands in Northern Ontario. Again, no instant-on that I saw.
4 "saves" (Ironically, all with my girlfriend driving - in all cases she had PLENTY of time to slow down to about 5 mph over the PSL)
1 "J" reading in heavy traffic
0 "E" readings
1 Laser False, also in heavy traffic near dusk (brake lights?)
What can I say? I'm very happy with the performance of this unit. I have to say that having it in the car was probably a deterrent to excessive speeding, since it kept my speed always on my mind. Basically I feel it allowed me to do 10-15 mph over the PSL (something I consider to be completely safe under good conditions) with a lot less worry about getting tagged.
When I would get any alert of any consequence in Ontario, I just turned it off after slowing to PSL+5-10km/h .
I also passed several OPP cruisers who were not running radar at the time. (visual deterrents!)
Anyway, I just thought I would share my experience on my new-ish unit.
