This LoProMoFo GoPro 9,10, 11 & 12 sticky mount does not need holes and screws. The mounts low profile sticks with 3M to your helmet shell and the case screws to the base. The camera angle angle is easy and quickly adjustable. 

Made from very resisting non cracking material this mount is light weight, completely snag free and allows to easily access the camera. The GoPro slides out within a second to access the battery or card and slides in using only one hand when you're wearing the helmet.

The installation is straight forward and easy and doesn't restrict your helmets visor function at all.

When jumping without camera or flying in the wind tunnel, the casing disconnects easily from the base by releasing 2 screws.
