The LARSEN & BRUSGAARD NEWTON RING-SIGHT is designed for easy mounting on any type of camera helmet. Its cross sight dead-center, once aligned with the camera viewfinder, enables you to aim the camera precisely at the target.
The special Newton Interference Pattern ensures that, no matter how the helmet may move due to air drag, you will always be able to point the camera at the target seen in the dead-center of the cross.
The L&B Ring Sight comes without the holder and clamp. These can be ordered separate.
