The SYNCHRONIZER golf swing training aid is an obscure contraption that actually works quite well although I think the same results could be achieved with a much simpler device. The training aid makes you clear your hips in the downswing to make room for your arms. If you struggle with distance or a bad path path in to the ball the chances are you are not sequencing properly and your hips are not clearing. Try this training aid or something similar to make you aware of your hip position in the downswing.
