Panoramic disc accessories are useful for creating an independently controlled panning axis for your equipment. A panoramic disc can be attached on top of a Gitzo Systematic Leveling Base, attached on top of or underneath another head that doesn’t have its own independent panning axis, or fixed directly to the top of Gitzo tripod columns to replace the tripod upper disc. The 3/8” thread & the included 1/4”-3/8” screw adapter allow the panoramic disc to be attached to various tripods, heads, & other supports.
