ABSTRACT:
A hand held instrument for determining the degree of angular deviation of a line between selected points on a subject from a gravity-dependent reference, including a transparent base through which the selected points may be viewed and a gravity-dependent indicator mounted on the base for free rotation under the influence of gravity. The base includes indicia complementary with the gravity-dependent indicator to provide an indication of the degree of deviation between the gravity-dependent indicator and the line between selected points on the subject when the instrument is held in a substantially upright position.
