Did you know we have tennis-product inventors in Women’s Tennis Blog’s community? Grégoire Gentil is a familiar name to all those active in the comments on this website and now I’m excited to tell you that he has created a revolutionary portable device that can be attached to a net post and detect whether tennis shots are in or out, with 99% accuracy. The GoPro-sized product, that will be available this summer for $199, has a simple and telling name: “In/Out”. Besides being designed to eliminate endless arguments over line calls, the In/Out helps players learn from their mistakes through HD video and analyzes their game through stats analysis.
No more drama: Portable, accurate, and affordable In/Out tennis line call device saves time and nerves!
