Simple, reliable, value, these three words sum up the SLIK Standard Ball Head-II but they do not address the high quality standards that are used to make this rugged ball head. Using precision machined aluminum components and advanced high impact polymers, the Standard Ball Head-II will yield years of trustworthy service. A large, circular mount area will give you camera the proper support while the free turning anti-scratch plate within the head will protect the bottom of your camera from damage and greatly reduce the likely hood that your camera could become jammed on the head. The perfectly sized release lever makes releasing and locking the head in any position very convenient and easier to use than other ball heads having small release knobs which can be over tightened and make fine tension adjustments difficult.
