I travel a lot on business and I normally take my GPS with me. I've also had trips out of the country twice this year with no problems (except lost luggage). I just stick it in with all my other electronic stuff in my backpack (I use a backpack instead of a brief case).  It is almost never searched.  I don't normally sit by the window, but when I do, I often get the GPS out and play with it.  I basically have to hold it right against the window to get a signal, but it is fun to see where you are and how fast you are going.  I've never been questioned by a Flight Attendant except to put it away for landing.

  Subject: [Az-Geocaching] GPS on Commercial Airliner?


  Has anyone had any problems taking a GPS receiver on a commercial airliner?  I don't want to put it in my checked baggage, but I don't want hassles with security, either.
