I havn't had a radar detector in my car in years, do you know if they are directional and need to be pointed at the source or if they are omnidirectional and pick up the signal from all directions?

I just skimmed the CARD website. I get the impression that it picks up the marine radar transmitted by the boat/freighter. Some of these are X band, some low S band and I think (??) some may be C band. The point being that only the X band overlaps the frequencies that might be used for speed measurement. I'm not at all sure a CARD system would detect a "speed gun" though it might be useful to detect the Raymarine radar that I see on most of the NHMP boats.
As for the directivity of your typical radar detector antenna ... they are somewhat directional but will pick up stronger transmissions off the side and from behind. The only one I'm aware of that let's you know where the signal is coming from is the
