With increased airport security, traveling with your CoxBox is trickier than ever. We recommend you check the CoxBox in with your luggage. Include product literature that explains what the CoxBox is. Brochures can be obtained from NK, or product literature can be printed from the website. Another option that may work when traveling overseas is to ship your units through UPS. If you do so, be very clear that these are used units, being imported temporarily. Put a low replacement value on them, but do note that you run the risk of the replacement value being used for customs. VAT (tax) is quite expensive and if they decide to hold the units in customs until you pay you could be without your CoxBox for the race.
