Endangered Art of Chaining Hub is for, Land Surveyors United members to discuss the Gunter's Chain and the endangered art of chaining in the land surveying profession. Share your best experiences and tips for chaining in land surveying.Gunter's chain (also known as Gunter’s measurement) is a distance measuring device used for surveying. It was designed and introduced in 1620 by English clergyman and mathematician Edmund Gunter (1581–1626). It enabled plots of land to be accurately surveyed and plotted, for legal and commercial purposes. Gunter developed an actual measuring chain of 100 links. These, the chain and the link, became statutory measures in England and subsequently the British Empire.
