The tape measure has remained virtually unchanged for over 100 years until now. The eTape16 digital tape measure revolutionizes not only the tape measure but also expands its utility as never before envisioned. The large digital display provides easy reading while the advance features are readily accessible. These features include 3 memories, US or metric units, centerline calculation, re-zero and Inside/Outside measurements. In addition to its advanced features, the eTape16 incorporates a sleek modern design. Made of poly carbonate plastic, the eTape16 is made to last in the most rugged of environments.
