Meet the TALON: a smart golf training aid that provides you with real-time feedback of your angles to help you improve your posture and game. It consists of a wireless back unit that measures your spine angle and a digital display unit that measures your club shaft angle. The unit attaches to the grip of your club and does not get in your way.
This training aid provides you with visual feedback on your golf stance and angles to take the guesswork out of the process. It also helps improve your muscle memory and consistency. Moving the digital display unit from one club to another is pretty easy, which helps. Yet another interesting golf product on Indiegogo.
