There are a great number of training aids out on the market. None that I've personally found yet that is entirely accurate. Zepp didn't work for me, but it may suffice for you. DuoTrac Golf is pretty snazzy. I like the idea of 4 sensors working together to better suit up your swing. It makes sense to measure swings on a plane instead of a point. https://www.kickstarter.com/projects/681483588/duotrac-golf-the-fundamental-swing-analyzer I backed it because the price on these sensors are competitive. Definitely looking forward to seeing some reviews on these guys.
