deWiz is a portable golf training device that provides instant feedback during a golf swing. The … [+] The deWiz app provides comprehensive swing analysis tools, and the deWiz wearable device provides real-time feedback through either an electrical impulse or an audible alarm when a golfer’s swing fails.


The differentiator for golf’s newest swing training aid, deWiz, is instant feedback that you can feel via an electrical pulse. The high-tech wearable – the result of five years of research, testing and development – is getting good feedback itself and from great champions such as Annika Sorenstam, Bryson DeChambeau, Vijay Singh, Lydia Ko and Henrik Stenson.

deWiz was founded in Sweden as the brainchild of former European Tour player Markus Westerberg and has sold his initial equipment allocation to early adopters. The company is now taking pre-orders in preparation for its wider launch this summer during the golf season.

Regardless of whether a golfer wants to focus on pace, swing level, transition or the length of his back swing, deWiz helps him to feel where his swing is going astray. Unlike other swing analysis tools or flight monitors, this type of learning stimulus is based on motor learning, according to Westerberg, and helps reduce the time it takes to rewrite the golf swing.

“For every movement, like walking or a golf swing, your brain has a script that executes it,” says Westerberg. “If you give instant feedback as you make this move, your brain can process this script exponentially faster than relying on the trial-and-error process of interpreting and translating data presented on a screen.”

Sorenstam was introduced to Westerberg and his co-founder Christian Bergh by Stenson a few years ago and, together with the other professional golf ambassadors from deWiz, helped to support the development of a revolutionary wearable in the training sector.

“I’ve always been fascinated by technology and I’ve never seen anything so advanced with instant feedback,” said Sorenstam. “With deWiz, practicing is more fun with the stimuli you feel immediately, and the precision of the data helped me be more consistent.”

deWiz tracks the position and direction of a user’s hands during the golf swing and offers 3D analysis in its app. The key aspect of the product, however, is the tickling electrical pulse (for those who are wondering, no, it’s not like a dog’s shock collar) as well as an optional audio signal that is delivered during the swing and located in the analysis via the app.

“One of the most important things a lot of amateurs will look at is the swing plane,” says Stenson. “We know that over-the-top slicing is something that annoys a large proportion of golfers.”

If, due to this swing error, a user hits strokes that intersect due to that swing error, they can adjust the deWiz parameters to reduce the exaggerated movements. If these parameters are violated, they receive real-time feedback. As Westerberg says, it reduces trial and error and speeds up the learning process.

“The challenge for a golf coach is to help a student make a swing change permanent,” said Westerberg, noting that a player can be relatively constant during a lesson but fall back into bad habits on the course – especially when under Pressure is on. “The same challenge applies to many training aids, because if you take them away, golfers fall back into bad habits. We wanted to change this cycle with a seamless solution and deWiz fulfilled what many golf coaches have dreamed of for ages: What if you could give feedback at the exact moment the swing goes wrong?

That is the essence of deWiz – swing, feel, improve. “
