deWiz Swing Analyzer Golf

I am crap at golf and this is for pros, hence I am selling it. Was a gift originally. A year old. RRP: 699 EUR. deWiz Transition is a distance measurement between the backswing and downswing hand path planes. A positive (+) measurement indicates the downswing plane starts above the backswing plane, and conversely, a negative measurement (-) shows the downswing dropping below the backswing. Most high-level players maintain a neutral transition (+/- 1 in), whereas players that struggle with big left and right misses tend to have more positive Transition measurements leading to less control of the club face. https://eu.dewizgolf.com/pages/dewiz-features
