A panhead (1) having a counterbalance action suitable for heavy cameras or equipment, and provides instantaneous electronic measurements of head settin gs and position. The improved counterbalance utilizes a dual-tower dual-axis no n- linear mechanism as well as position encoders indexed to each axis (7-13) of head movement. Potentiometer setting detectors are also indexed to settable adjustments to read and relay such adjustments, and an electronic display (2 5) conveys information regarding the current positions and settings of the came ra head (1). A novel mounting system situated at the top of the head provides f or fast and simple mounting and unmounting of equipment or a dutch roll head. I n particular, a novel dovetail (19, 21) engagement mechanism swings a dovetail side down during detachment. In an embodiment of the invention, the dutch ro ll head can be remotely proportionally actuated by a user via a switch mountabl e to a handle used for panning and tilting of the pan head. |
