The GH03 head features an Easy Lock Baseplate system that combines the balance adjustment of a sliding baseplate with the ease of a quick-release system. It provides a fixed counterbalance that helps the fluid head support loads up to 9 pounds. With variable fluid drag on both pan and tilt, you can adjust the fluid head to suit your shooting style or the needs of the shot. The head features a built-in 1/4"-20 accessory socket for available monitor support arms or other accessory items.
