The Smooth-C features pan following, locking, and following modes, and offers 320° rotation along the pan, tilt, and roll axes. For operation, it has a 5-way joystick at your fingertips that allows for speed regulation and angle control. The Smooth-C is designed with short-circuit, reverse, and over-discharge protection that ensures continued safe start-up. This stabilizer comes with two batteries that provide approximately two hours of runtime each, and that can also be used together at the same time if you incorporate an extension tube, sold separately.
