I never let any of those metal detector monkeys touch any of my camera gear. Even TSA.I went there last year and they were wanting then. I anticipated it and as such left my hardware in the car. What pissed me off was their treatment of my camera gear. They were extremely7 careless taking gear out of the bag almost dropping one of my bodies. I tried to complain to management once inside and they literally said that they "could do nothing" and if I didn't like it we could leave...so I did. Never to return! I won't share my money with idiots.
If it becomes an issue, I'll ask for their supervisor, then explain the replacement costs involved.
For a zoo, that might mean my Nikon 200 f/2 (with a D850 body, in the neighborhood of $8,200).
I'm OK for an inspection, but we'll agree up front exactly how that will be performed.
