I am an amateur chess player and I plan to fly from the United States to Europe with the following clock:
I'm afraid the clock is a bit "scary". It's also quite sturdy and made of metal (aluminum), so I guess (my Physics is a little rusty) it's like a Faraday cage with mostly empty space (basically tiny electronics, wires and two batteries AA). As such, I am not sure how this is displayed / recorded on the hardware they use and if this could worry the operators.
Is it safe to assume that I can take it with me in the cabin as checked baggage?
Or should I possibly take it with me to the airport already open for them to inspect its contents? (You must unscrew a panel to change the batteries or see what is inside – a screwdriver is needed).
