The Drift Helmet Mount for HD170/X170 Cameras is a quick-release mounting kit for attaching a Drift HD170 or X170 action cam to a helmet or other curved, smooth surface.
The mount attaches to the helmet surface via industrial-strength adhesive pads and a hook-and-loop fastener. The camera plate attaches to the mount via a quick-release element, allowing you to quickly and easily remove the camera with its plate attached and re-attach it to a Drift Handlebar Mount, for instance.
The Drift HD170 and X170 both come with a Helmet Mount; this is a replacement kit. The Helmet Mount is designed specifically to mount the HD170/X170, but its camera plate's standard 1/4"-20 screw will fit the tripod thread of many other camcorders.
