Extremely convenient 3

Yes, very practical, because a GoPro is small, but in general we like to have a lot of accessories with.
In this briefcase I put 1 or 2 GoPro (if I have one, I have a second chamber), all fasteners and teasers, microSD card deck, float, charger, USB cable and a few extension cords, + batteries, LCD display and remote control.
The cameras, screens, batteries and remote controls are obviously very tidy and held in place ... for the rest, well, it wanders a bit, but nothing too bad.

What more?
