The equipment in this industry can look pretty funny on an x-ray. A clear explanation can go a long way. If you are using a hard travel case filled with foam, print out labels, and stick them under each item with a bit of superglue. This will make it obvious when you write 'underwater batteries' next to those large cylinders with wires hanging out. The nice guys behind the scenes won't be getting worried. There are horror stories of airline security officers prying open underwater camera cases with flat-head screwdrivers. How do you think your seal will take that? We are aware of ongoing settlements with the airlines due to improper handling of imaging equipment.

This note should be duplicated in the language of the country you are travelling to.

This can make the handling of your luggage go smoothly. Write it up once, modify and print it out for each trip. Be sure to be thorough, this can also be used back at home as an inventory of your case. Take a digital picture of your items, and leave that at home with the inventory list, just in case something should happen.

Here is a suggestion for a start:

Dearest Inspector,

You will find the following items in this case:

1. Camera Housing, Black Aluminum
2. Handles, Black Aluminum
3. 2 Battery Chargers, Black
4. ....

Thank You

The 5 minutes that it takes to right the note and take a picture can save you hours of headaches and travel nightmares! Good luck and safe travels!
