If you have a monopod but no tilt head on it, don't hesitate!
Very practical small head on a monopod to be able to be much more flexible. Reliable, even with a lot of weight on it such as with a 200-500mm telephoto lens and D500: sand without worries.
Pro
Very quick and easy to install
Very fast device attachment
Very good behaviour in the absence of the axis
Contra
Can become very slightly out of shape when you have a lot of weight on it
