Or you can try out this little trick....
Wrap the gear in one of those flat-paper USPS Express envelopes, then put it in something else. Even if someone finds your hidden envelope, they still can't open it without a warrant. Most likely, they will just drop the issue because spending all the time to get a warrant is too much of a pain in the ass for them. If they can't rip it open immediatley (like the rest of your luggage), they won't waste their time. They are lazy people to begin with.
