Recently switch to carrying an EPLB instead of a Nautilus (bought the first year they came out) and a DRYFOB to carry the EPLB during the SCUBA dive. So taking an international flight the question occurs to me of "Where to I pack it?" Given it is a metal cylinder of some size I imagine TSA and others when seeing it on a scanner would want to examine it. So that would argue for the Carry-on, or should it be in my Dive Bag? Thoughts? TSA what say you?
