Martin, thanks very much for the list, it is very informative.
However, nothing takes the place of asking someone of their experiences with regards to the actions of the TSA and one can not be sure that what passes in one area/airport will or will not pass in another.
Haviing the list is one thing, discussing experiences is something else.
I was stopped at LAX and told to remove my six eyeglass repair kits, as it was prohibited to carry more than one. The list clearly indicates there is no limit applied to this item. Since the item is listed, with no limit to quantity shown, it does not fall under the discretion of the TSA employee, if you take the form at face value.
I use them as handouts for customers wearing eyeglasses and they are usually appreciated, hence having more than one with me.

So, once again, thanks for the list. I sure hope you were not offended by the question being asked about the tripod. Even though it may be covered in general under "Camera Equipement" I could see a TSA grunt saying "No" to a carry-on. If you are stuck in a situation like that with a $200 tripod, it is definitly decision time. A little knowledge ahead of time might help a great deal.
After all, it is a discussion forum.
I will print the list and carry it with me.

Thanks again.

Cheers!
