Keson Metal Professional Measuring Wheel

The Keson MP301 Metal Professional Measuring Wheel is slightly more compact than the MP401 wheel, offering very good approximation when measuring roads and construction sites, garden size, building interiors, railroad tracks, and the likes. It measures up to 99,999 digits with an accuracy of 99.7 percent. With a three feet circumference, it works well on uneven terrain and can still provide accurate measurements. Plus, its handle extends from 21 to 36 inches.
