I have 3 of these...they are tanks.

But I am constantly worried about losing a whole case...because then I potentially lose 4 cards instead of just one...I've never really figured out a totally foolproof method...thankfully I've never had any close calls either (knocks on wood).
I need a camera that does an automatic online backup

for me, same idea as your pelican but more brightly and obnoxiously colored, I had a pelican one, I plastidipped it road cone orange...
I also make sure that I am deliberate about how I put the cards back.
Brand labelling facing me is empty, used is facing away. Once I get below 80 shots remaining I change cards at the first opportunity as well...
