The Keson OTR (open type reel) series of measuring tapes finds the most favor in industrial/construction applications, although others often select it.
The Keson MC (closed metal case) is most often selected by realtors and appraisers because:
1)Its compact size makes it easier to carry in
pocket, purse or briefcase.
2)The closed case keeps your clothing or other
carrying location cleaner...any dirt or moisture that
gets on the tape ends up inside the case, not inside
