It's similar in appearance to the metal detector, but as you stand in it it puffs air at you from various angles. Sensors then "read" the air to see if you're giving off chemical traces from nonmetallic explosives, etc.

That should be interesting, I do a lot of reloading and I would imagine that single and double base powders give off a lot of dust that might sound the alarm. Another good reason to stay away from those paranoid ones at the airports.

Yep, I've had to have hand luggage screened with the "explosives pads" for the same reason - made me segregate my luggage more completely. Range bags no longer go on the plane!
