This is the SP Gadgets: Flex Mount. This is a magnetic mount which allows you to mount your GoPro camera to many surfaces where others don’t. In this video I show where I have used it on glass and how easy it can be used to hold the camera in place on a kayak. The Flex Mount also has a velcro strap on the back that allows for it to be attached around a belt or a strap on a backpack.
