Where my Radarbox is positioned I have a pretty good field of vision, talking actual vision here not Radarbox, over west central Scotland. But I got so fed up opening & closing the window trying to see aircraft on the fringes that I decided to print off a compass,set it with an actual compass & cut to the extremes of my view out the window.I have taped it to the window-sill & can now see at a glance the bearing etc.
At this point someone will of course come in & tell me that there is a field of vision option on Radarbox LOL
I have not posted this for any other reason other than to illustrate that after 1 week of having this thing I am beginning to doubt my sanity!
