Qwik Caliper $9.95The earliest caliper was first discovered on a shipwreck off the Italian coast — a practical tool for sailors taking quick and exact measurements. Today’s boaters in need of such measurements have the Qwik Caliper for measuring the outside diameter of round objects. The simple and compact tool is useful for boaters measuring everything from spars and winches to stanchions, lines and engine filters. The caliper’s blades are held astride the round object, and the outside diameter is indicated when the scales touch the object.
