The Sirui HA-77 horizontal arm is a telescopic cross arm that can be combined with a tripod or a base to create a miniature camera arm. Its total length of 77 cm is provided by a two-section tube that rests on top of a tripod head, which features 360° independent rotation. The tube and head are connected by a support point, which allows for a 90° tilt up or down that can be locked in place. This allows for easy lifting of an attached camera towards an elevated subject or over a scene. For subjects along the ground, the HA-77 horizontal arm can be used to achieve low angles while the user stands comfortably behind the camera.
