DeWiggler™ is an automated calibration tool The most important mission of an instrument system is correctly reporting wind direction (see Importance of true wind). If lifts or headers occur every time you tack or gibe, there is a problem with your instrument calibration. DeWiggler is the solution

Here’s a term that is bandied about in measuring Wind Direction, but is commonly misunderstood: upwash. Many people think they understand what it is, but are wrong by 90 degrees. What do I mean by that? Most people hear the term upwash and take it for face
Learn more →Calibration makes your instruments more accurate and useful Sailing instrument calibration systems is necessary to make displayed information correct and useful. Instrument systems use sensors to measure primary environmental factors (boatspeed, wind, heading, position, heel and others), possibly combine them, and display the results. Calibrations adjust for
Learn more →The story of one boat having calibration problems was recently relayed to us. The crew was having difficulty obtaining reasonable numbers from their instrument system, so they began to “calibrate” the instruments. I used quotes because what they were doing was not actually calibration, but fiddling and

It is also widely available, so it can be obtained fairly easily (including through our Web Store). It can also be calibrated
