I'm wondering if airport security is going to have any problem with freediving weight as part of carry on luggage? Mine is self-made of lead shot, like most of us do, it took me some effort and money to make it, so I don't want airport security to confiscate it. Once at airport, they took away my toothpaste, although sometimes, they are ok with it, nowadays, I travel with travel size toothpaste, but I can't really use a "travel size freediving neckweight". Has anyone had any bad experience with neck weight at airport? Thanks.
