The SP36P is a highly technical ball head. It has both upper and lower panning controls with degree marks. The main tension control is generously large and easy to use. Integrated into the tension control is a memory lock dial for setting a repeatable tension stop. Both a high-rise and low-profile memory lock dial are included so you have the choice of which to use.  The ProMaster dovetail quick release system is easy to use and is compatible with a variety of arca-swiss type quick release products.
