Review on 📏 Lufkin W606PD Executive Diameter Engineers: Precision Measuring Tool for Professionals by Fredrick Edwards

This is an easy to read tool for quick diameter/circumference measurements. My only issue is that when I read the diameter (at least when measuring an 18" roll circumference) it's off by about 10 mils (0.010"). The roll I measured was exactly 18 inches on one side of the tape. I also tested this measurement with another tape. Reading the diameter with this tape, it read 5.72. Using the Pi to find the diameter 18"circumference gives you 5.729582791". I don't expect this tape to read that accurately, but the Pi's solution is almost 0.010 more than the reading from this tape. I need to do more testing, but if it's consistently -0.010, I might add this to the Total value of readings from this band. It would be nice if the manufacturer investigated and fixed this problem.
