Web Pricing - Why are the prices on this web site different from those in your stores?
Our stores are staffed with a wide variety of product specialists and support staff, each of whom make an effort to be responsive and pleasant to deal with. We're also able to provide a customer with any item from our inventory to inspect and test. The cost of this customer service is an increased overhead for our in-store prices, to pay for the store space, the training of our employees, and other considerations not present online. We're happy to offer reduced prices online and hope that you will be satisfied with your purchase no matter where you decide to buy.
The Manfrotto Hydrostatic Arm features a new locking mechanism. A ball pivot encapsulated in a hydraulic oil-filled chamber enables the arm to be locked in position with only a gentle turn of the knob. This is accomplished by the fact that the oil surrounds the ball joint and applies pressure evenly, as opposed to a traditional lock that simply jams a screw or cup against the ball.
The 8191 Medium Hydrostatic Arm spans 7.1" (18 cm) and is a perfect bridge between a video camera and a small monitor under 4.9 lbs (2.2 kg) in weight. It also features both 3/8" and 1/4"-20 pins with standard tripod/camera threads.
