Eclipse SD12UK Spring Divider, 12"

Spring Divider, also known as the mathematician's Compass is used as a Point Marker. Sharp points can envision visible Arcs or Circles which comes in handy when measuring point-to-point distance. You just need to tighten the screws, spring the magic Web, and have the path map in mind. Mathematics can take care of itself.
