The E-Image GH04 Fluid Head has a recommended payload of 13.2 lbs. and can switch from having a 75mm ball for tripod mounting to having a flat base with a 3/8-16 mounting point. To transition from ball to flat, simply use the included 3mm Allen wrench to loosen the three locking bolts on the underside of the 75mm ball mount and twist the ball mount counter-clockwise. Pan and tilt drag are installed and set at a fixed amount for light cameras. The same is true of the installed counterbalance.
