The Deluxe Inclinometer has the same two bases as the Universal Inclinometer, but has an upgraded 3 inch dial which is readable to one degree increments. The ball indicator reduces sensitivity to vertical orientation. The rubber footed base is ideal for spine measurements while the long base is used for making arm rotaion, and extremity range of motion measurements. The Deluxe Inclinometer comes standard with both bases and an instructional card for easy reference.
