Looking for advise on traveling with FIX uw case for my g11 canon. I am more used to traveling with the canon housings where I just remove the o-ring and clamp shut the case with the o-ring inside. It is a thicker o-ring that is easy to seat and fit without issues. I am a little more concern about the FIX case as the o-ring is much smaller diameter and I would rather not fuss with it. Should I remove it anyway or clamp the housing shut with the o-ring in place. I will be flying so I don't what to have a difficult time opening the case when I land.
