Keson RR3010 3 ft. Measuring Wheel - Measure in Ft. and 10ths
MADE OF KESONITE™
  There are inherent vulnerabilities of die cast and metal spoked
  wheels. Everyday use requires that a wheel handle some rough
  treatment without dents and without bending.
  Not all wheels are up to this. Our solution? Invent a new
  material. Kesonite is a strong, dense metal/resin composite.
  It holds its shape better than metal and it’s stronger than a
  spoked or die cast wheel. The weight of the wheel makes it
  easier to use and more accurate on rough terrain.
  Based on the design of the RR Series Large, a model with over
  20 years of continuous improvement. Includes a NEW wheel
design, material and safety reflector!
  EASY-READ,
  MAGNIFIED COUNTER
  5-digit, easy-read, magnified
  counter measures 9,999 feet, 11
  inches (9999.9 ft on engineers’
  model and 999.9 meters on metric).
  NOW WITH A 3-PC. PISTOL GRIP HANDLE!
  The same outstanding features, benefits and reliability of our
  previous 2-piece handle version with the added convenience
  of our new 3-piece, pistol grip handle. The twist locks have
