I've walked right through airport style metal detectors with my Schoeps rig and don't beep (my cell phone and keys always go into a tray) on the way out once I walked back through with keys/phone and it went off) They ain't looking for us with these things, they're looking for a certain mass of certain metals which would imply weapon...most gear these days (except maybe an SD unit) should go in no problem. key is know your rig and know what might set it off, and change out that piece of gear.
