The 6-1/2ft GAMMON REEL® is a Surveyor's Plumb Line Reel used in surveying and construction to set up and deploy a plumb bob. The GAMMON REEL® allows surveyors to quickly and easily set up, deploy, and adjust for an accurate plumb line. This helps determine verticality with respect to gravity, essentially helping to place an instrument over an exact point in space to accurately set markers. Simply slip the reel into your palm. Draw the bob to the desired position and stop with finger pressure. The steel clock spring zips the string back into the case.
