Wheel Master 4D
Calculated Industries created the Wheel Master 4D with balance and accuracy in mind.
This is a small measuring wheel. It has a 4" diameter (which equals a 12.6" circumference) with dual wheels. The dual wheeled measuring wheel makes it easier to hold the wheel steadily to ensure more accurate measurements.
The average accuracy is at 99.7%! This wheel can measure up to 6 digits which would track up to 9,999' 11". It has got a telescoping handle with snap lock that opens up to 42" so that you can adjust the height to your individual comfort zone. In addition to the available travel case (sold separately) the actual 4D wheel can collapse down to 20", making transportation really easy. Additionally, the ergonomic pistol grip handle makes it very easy to use. The wheel has reflective tape for added security.
Use your Wheel Master with confidence. The 4D measuring wheel lives up to Calculated Industries' standards of quality, accuracy, and dependability.
