I'm not sure what I would do. It's been two years since I last flew on a commercial flight and 4-5 since I flew on a small private plane. I guess I would use the scanner but I wouldn't like it if it was revealing...
Last thing I would do is fight TSA over it.
On one business trip I forgot that I had my work leatherman tool in my backpack and they nearly had an emergency alert when they discovered it as I was going through the line. This was at Burbank airport. They asked me to take it out and stow it with my luggage. So it cost me 15 minutes but ended without incident.
