The Explorer EX-XL Epic Explorer Extra Large Ball Head is the ultimate professional ball head designed for the toughest tasks. A key feature is a hollow body and spherical socket designed to minimize weight to just a total of 19.8 ounces, while maximizing strength, durability, and load capacity of 88.2 lbs. This makes the EX-XL Epic Explorer suitable for supporting larger telephoto lenses while being light enough to carry and use with camera bodies and lens combinations of all sizes. Ball heads increase stability compared to other head types and provide faster, more accurate camera rotation for photographers. The head tilts 90 degrees for quick and easy upright orientation. The large main adjustment knob features a friction-controlled rubber grip and a separate 360-degree panning clamp to assist with quick, precise adjustments, so you never miss the action. The ARCA/RRS compatible quick release clamp makes it compatible with a wide range of quick release plates and L-brackets and includes an Explorer EX-60 QR plate in the box. A 3/8 inch thread socket and included 1/4 to 3/8 inch brush fits tripods from many manufacturers. The clamp features the same hollow ball head design and an extra-large release lock so the camera doesn't obstruct the release. The Explorer EX-XL Epic Explorer Extra Large Ball Head is CNC machined from aircraft grade aluminum alloy and anodized with an oxidation treatment ensuring durability
