The HA-77 Horizontal Armfrom Siruiis a telescoping cross arm that can be combined with a tripod or stand to create a miniature camera boom. Its total 30.3″ of length is provided by a two-section tube that rests on top of a tripod head, which features 360 of independent rotation. The tube and the head are connected by a fulcrum, which enables 90 of upwards or downwards tilt that can be locked into place. This allows an attached camera to be easily raised toward an elevated subject or over a scene. For subjects along the ground, the HA-77 Horizontal Arm can be used to obtain low angles while its user stands comfortably behind the camera.
