This is about as low a tech device as you’ll find. But it’s a good one. With the Swingyde it’s all about wrist position which can be a bit baffling to beginners and experienced golfers alike. Once this plastic device is installed and aligned properly–which is a bit of a challenge (careful you don’t snap the part that connects to the grip of any club, for if you do, it’s off to the circular file with this device)–it helps you see if your wrists are in the right position that will, ultimately, insure that you release your wrists at impact properly. That’s of great value and about the only device I’ve come across that specifically helps you do that. If the wrists release properly, you’re more insured of squaring up the clubface at impact when the club is moving fastest and without chicken-winging your forward elbow, a common error.
One disadvantage is that it only focuses on releasing the club properly for straight shots so if you’re wanting practice on holding off the club to intentionally fade the ball, it won’t help with that. But that’s OK, since before you start intentionally fading the ball, you’ll need to learn how to hit it straight…consistently. There’s only one Bubba Watson!
It’ll also help with your grip, making sure it’s in your fingers and those Vs are pointing toward your trailing shoulder. If your left hand is too weak, or if your left arm collapses on the backswing, the curved piece at the end of the device will not strike the left forearm at the proper position on the backswing and the follow-through. At impact, the piece does not touch the forearm. There are clear instructions and a CD included.
It seems to be designed for use on one club only, but with some effort it can be changed to different clubs as well. It can be used to hit balls, mostly with 3/4 swings. It should only be used on the range with a ball, or, without a ball, anywhere you won’t smash a lamp or put a hole in your ceiling!
The Swingyde, developed and made in Australia, is inexpensive and comes with a wrist/forearm guard and large rubber band (for what, I haven’t yet figured out). I recommend it.
Note: On installation, I’d suggest slipping it on the thin end of the shaft, then sliding it up to and on the grip. Less chance of that piece breaking.
