I just started using my new X50 last night. I have not had any LEO encounters yet, but I have driven past a couple falses, a store with automatic doors and a construction sign. I was not warned until I was on top of these falses. Now I vaguely remember someone else posting a thread similar to mine, some time ago. My question is, are falses that weak that you won't detect them until you are right on top of them, or should your detector be picking them up from further away? I'm certainly hoping for the former.
