Handheld spring scale designed for racket sports, compatible with all stringing machines. Most accurate results are achieved when used with polyester tennis strings.
Consistent tension readings - with a calibrated spring scale
Calibrated spring scale measures tension in both kilograms and pounds, with a readable range from 0-80 lb across five centimetres. A simple spring mechanism converts pull force into a numeric reading on the scale face.
Consistent measurements help match string tension across rackets, reducing variability between jobs and improving playability and feel.
