The award-winning RigTune Pro rig tension gauge lets sailors fine-tune rigging with digital precision to the nearest kilogram, eliminating inaccurate spring-loaded gauges and conversion tables. The RigTune Pro works by deflecting the rigging over three pins on the back of the gauge. A load cell records the pressure on one of the pins and displays the measurement on an easy-to-read screen. Sailors can record their fastest settings and reproduce them for each regatta with dependable repeatability. The Harken Rigtune Pro was conceived and designed by Lou Varney of Diverse Yacht Services/Tropical Engineering and developed by Harken UK.
