Abstract: A manually operated distance measuring tool is a ring which is manually rolled along the ground. The ring is provided with a coating having equally spaced imprinted measurement marks on the inner surface. The ring has diameter providing for a ten foot increment for each complete revolution of the circular member. Thus the number of total revolutions is directly covertible into a whole number of feet by merely adding a zero to the number of counted complete revolutions and then adding the final reading. The marks are measured from a starting location identified by an encircling tape of a different color and center enlarged loop. In using of the tool, the operator rolls the circular member along the ground manually and mentally records each revolution from the starting point to the finish point. The final measurement is recorded in accordance with the specific marking.
