Having a 360 Quick Connect mount on your GoPro 3-Way or other selfie stick, gets you a whole new set of angles you can work when you are shooting your selfie. Having a 360 Quick Connect connector on your pole gives you 2-Axis movement at the tip of your pole so you can shoot high and low angles and still have the GoPro at the correct angle for the shot.
Being able to rotate your GoPro on the 360 Quick Connect Mounting Stud and also being able to pivot your camera on the camera mount gets you every angle you need to shoot amazing photos and video.
