Here's a picture of the Tripod/Monopod Head I use,,It simply unscrews from one to the other,,It has a ball & socket type joint,,the bottom is slotted for vertical Adjustments,,By simply squeezing the trigger it can be rotated to any position,,The normal heads require both a horizontal & Vertical screw to be loosened for it to be Re-positioned,,I find this one is perfect for moving targets also,,,Plus it only cost about $60 with the plate for fixing to the camera included,,Hope this Helps,,,,Mat
