Waywisers were used by the ancient Chinese and Greeks, but became popular in the 18th century as the need for surveying increased with the enclosures and canal building. They translate the length travelled by the circumference of the large wheel to distance which can be read off the face.
Waywisers are also known as odometer, surveyor’s wheel, or perambulator.
