+ Machined (not cast) from high grade aluminum. The quality of these heads is evident.
+ QR plates are arca-swiss compatible with an incorporated safety catch mechanism.
+ Knobs are a rich red color so you can easily identify touch points on the head.
+ SP heads can pan from the base or from the top platform and have engraved degree-markings. Use the lower panning base for the initial framing of a shot followed by the upper pan to rotate the camera without affecting its other positioning.
+ A large tension control knob is easy to use, even with gloves.
+ Inside of the tension control knob is a secondary knob called a Memory Lock. It sets a repeatable tension when moving the camera on the ball head.
+ Two memory lock knobs are included with the ball head. Choose the protruding Memory Lock knob for ease of adjustment or switch it for the low profile Memory Lock knob which avoids any accidental changes.
