Does anyone have experience or knowledge about whether something like a Wimberly Sidekick causes concern for the airport security people? I'm flying to Africa and hope to keep the sidekick and Acratech V2 ballhead in my carry-on. However these look like strange and exotic objects to non-photographers.
Check with your local airport or carrier what the rules say about ballheads and similar items.
I'm fairly certain that ballheads need to be checked in, though I don't know the regulations in your country (whatever that is).
