(From company literature) Gitzo G1570M Low Profile 3-Way Pan/Tilt Head. The G1570M Low-Profile head provides solid support and flexibility for heavier large format cameras. The distance from the top of the tripod to the camera platform is reduced to ensure that the camera's center of gravity is kept over the middle of the tripod to avoid the possibility of overbalancing.
All models pan smoothly through 360 degrees, and provide a vertical tilt of +90 degrees, and -20 degrees. Side to side movement is 60 degrees to the left and 90 degrees to the right, allowing the photographer to direct the camera at virtually any angle without compromising on stability.
