I have the Passport 8500 X50 and have had it for about a month now. I have had 2 saves so far and it does work well, just that its multanova performance varies! I know this is due to it being a Wideband Ka detector etc...
For example, about 2 weeks ago I was driving in the country and got 500 - 600m on a multanova 6F. That was incredible range, however, it has also been known to give as little as 3-4 seconds on some multanovas as well. Earlier today I went past a multanova and only got about 4 seconds so I went back past it holding the detector vertical and I got literally 3-4 seconds more.
So I was wondering if anyone knows where I can get a vertical mount from, or don't they sell such an item? Has anyone else witnessed the better performance from mounting the detector vertically?
