I suppose "extremely valuable" is in the eye of the beholder but, I routinely travel with video production equipment valued in the $10s of thousands. I've never had an issue, after having requested a supervisor and explaining what I have and how it has to be treated. The gear has always been more-than-thoroughly inspected, swabbed and tested but I make certain to leave an extra 30 minutes to get through their theatrics. My gear remains unscathed.
