Designed by Sports Motion, our low-reach adapter arm extends the camera mounting position below the tripod at near ground level. This is essential for capturing foot and leg motion of runners or other athletes as well as patient leg movement for physical therapy. Although you can simply point the video camera at a down-angle, this usually produces a distorted and inaccurate video image. For best results, the video camera should always be located at right-angles to the subject being captured which, of course, is difficult at ground levels unless you have such an adapter.
