Here's just lil trick I started using this year. I was digging through all of my turkey huntin stuff and found some old diaphragm calls in a case and the calls were trashed (from being old), but the case was still good. Well I have 3 game cams set out right now. So I found out that the sd cards fit perfectly in the old diaphragm call case. That way when I pull the cards or go to put them back in, I don't have to worry about carrying multiple card cases and losing/damaging them.
