The

from
Really Right Stuff
is an Arca-type compatible dovetail equipped, 360-degree panning base that features a screw-knob equipped Arca-type clamp.
For panoramic and landscape photographers, the PC-PRO base allows the user to rotate their camera 360 degrees on top of a tripod, ball head, or other support.  The base may be attached to a support or Arca-type equipped ball head via the integrated Arca-type dovetail, a 3/8"-16 threaded socket, or a 1/4"-20 threaded socket.
When in use, the rotation of the mounted camera may be accurately monitored via a laser engraved degree scale which features markings in 2.5 degree increments.  When the photographer decides on a stopping point, the rotation may be locked by an integrated screw knob.
The clamp diameter is 2.9 inches, total height is 1.4".  Clamp length with knob is 4.5".
Includes single bull's-eye bubble for accurate leveling.
