Its a tripod, its a selfie stick, its all of these!
This GoPro 3-Way Grip Arm-Tripod Mount does it all: camera grip, extension arm, or tripod. The folding arm is perfect for POV or follow footage, and makes it easy to capture selfies without the mount appearing in the shot. When detached from the arm, the handle doubles as a camera grip. Stored inside the handle is a lightweight, mini tripod that can be removed and used on its own or combined with the handle.
