Tallying Taped Measurements. At the initial point the rear tapeman holds one pin and the head tapeman begins with ten pins carried on his steel ring. This is the reason why a set of eleven pins is normally used during taping operations. The first pin which the rear tapeman hols indicates that one tape length has already been measured, and the total numberof pins in his possession (not counting the pin still set on the ground) indicates the total number of full tape lengths that have so far been measured.
