A strong NEWTON SIGHT HOLDER with pin, screw, washers, Allen key and instructions for quick mounting on the helmet can be ordered separately
MOUNTING HARDWARE INSTRUCTIONS
Carefully cut/drill a hole (6 mm) in the helmet above the right or left eye. Mount the NEWTON SIGHT HOLDER pin.
Fasten the NEWTON SIGHT stem on the Holder. Put the helmet on and adjust to place the sight in front of the eye.
Switch-on the helmet mounted video camera/camera. A person looking in the viewfinder should point the helmet and camera in a direction that will place an object in the viewfinder dead center. While the person keeps the object fixed in the dead center the NEWTON SIGHT screw is loosened slightly and the sight adjusted to place the same object in the cross sight dead-center. Then tighten the screw firmly.
For optimum result the above procedure may be repeated several times.
