Of course, the carrier should not be too quick head movements and look for a while in the direction so that the viewer can just starting later on video recording something with the result.
It very useful to be able to remotely control GoPro with the remote control or the app, because then you have the camera does not lose weight, or may, if it has another on, check, so that the wearer does not have to take care of them. Only in 3D can not remotely control it, here you have to unity oh time and run when they are not wearing myself.
Even in 3D with the corresponding housing (if possible with a second fixed end at cinching belt holder) works quite well, but then the weight of the unit Kamara is clearly noticeable. That must accept the carrier. As an alternative, if nothing blocks the view in front of the chest, the chest mount.
Nor can the headband good about helmets (fire and soldiers helmet) drag, so anything on the helmet must be stuck and the whole thing can be removed quickly after the films.
Who has a corresponding interface program can also record a normal video camera and later encode two perspectives or combine the images, resulting in very great effects.
The headband is therefore a highly recommended accessory for GoPro.
