However, things and rules change all the time. I would suggest you disassemble your detector and pack it securely in your check in baggage. I've had no problems doing this. You may run into trouble if you try and board with it: electronics, small box, and batteries, heavens NO! You get my point. If your willing to purchase a hardcase, pack it well and check it in with your luggage. Best way in the world to have absolutely no problems would be to grow a beard; wrap your head in a turban, dress in a sheet and sandals, and if anyone asks you any questions while boarding the plane ask: "Are you threatening me?" Be sure to say it with an eastern accent. They won't bother you at all as they are afraid of "profiling." Now me, a white guy from the south...hell no! They frisk me and my friends like we asked for a tick check at the massage parlor. Any concerns just call or better yet drop by the airport and speak to one of the bosses. They'll give you the current scoop. Good luck, David@Dixie
