Proposed by the professional: Stable "Distance" and "Directionality"★ Trained the谷三姉妹 (Tani Three Sisters) into professionals★ The astonishing practice machine by Pro Kiyohiko Tani★ Tani Swing Checker PAT1616163

If you receive one-on-one instruction from a professional! Good news for golfers who are frustrated by that! This practice device, "Naruoto Checker" and "Wrist Put," was devised by the father who trained the谷三姉妹 into professionals, utilizing over 30 years of experience as a lesson pro. The two functions are: the Naruoto Checker, which sounds a tone when the wrist turn is performed correctly, and the Wrist Put, which alerts you if you maintain a consistent swing plane. It is a superb device.

The usage is simple: just attach it to your left arm and practice. Indoor practice without holding a club is also possible.

Golf often comes with endless worries. Even if you understand swing theory, for some reason, the ball does not fly as you wish.

Everyone has experienced this, but the reason is only one: you are not swinging as you imagine. It’s surprisingly hard to realize, but first, you should correct your form to the ideal using the "Tani Swing Checker."

**If your wrists are used correctly, the ball will fly farther and won’t curve**

"Distance and directionality may seem mutually exclusive, but in fact, they are naturally compatible. The 'swing that flies straight and doesn’t curve' is the fundamental of golf," says professional Kiyohiko Tani.
Directionality is achieved when the swing plane is maintained consistently.
Distance depends on correct wrist movement at impact.
While it is often said that conscious wrist turn at impact is bad, this applies only to amateurs whose swing plane is inconsistent.
Pro golfers, with stable club head paths, practice consciously turning their wrists to increase distance.
They know that the key to wrist turn is within 30-40 cm after impact, when both wrists are closest.

Specifically, if you can correctly use your wrists while keeping the club on the swing plane, your driver’s distance will undoubtedly increase by 20-30 yards.
For irons, the difference can be about one and a half clubs.
Of course, the ball will not curve.

**Check your swing plane and wrist turn yourself**

"Among amateurs, there are expressions like 'it flies but curves' and 'it doesn’t curve but doesn’t fly.' These people all have swing flaws. Those who curve the ball are swinging incorrectly, and those who don’t hit far are also swinging improperly," continues Tani.
The mechanisms for the ball flying far and not curving are fundamentally different.
People who curve the ball do so because their club head path is incorrect; nearly 100% of them bend their left wrist backward during the swing.
Those who don’t hit far do so because they pull their left elbow backward after impact, preventing proper wrist turn.
Such swings put strain on the body, eventually causing back pain or tendinitis.

"I have long wondered if there is a way for golfers to check their own swings. The result is the Swing Checker. Using this device, you can learn the correct swing plane and wrist turn simultaneously," says Tani.

**A swing that flies far and doesn’t curve remains effective even after removing the device**

"When you perform the wrist turn correctly, a faint sound will notify you in the zone about 30-40 cm after impact. Also, if the back of your left hand does not touch the Wrist Pad during the swing, it indicates that your swing plane is maintained," explains Tani.
Since practice is based on not consciously thinking about wearing the device, removing it will not change your swing.
It is also possible to practice at home without a club, leading to faster improvement.

"Golf students using this device have shown remarkable progress. Moreover, once the technique is acquired, it never leaves you," Tani says.
Flying far and straight—this is a golfer’s dream, and it seems the Swing Checker can truly make this a reality.

Golfers’ physiques vary; some have long arms, others short. It’s not possible to specify a universal attachment point like "a certain number of centimeters above the wrist."
The attachment method is simple; follow the instructions in the manual to fit it at the correct position suited to your body.

The Swing Checker has two functions: the Sound Checker and the Wrist Pad.
Right-handed golfers should set it on the left arm; left-handed golfers on the right arm.

The belt can be adjusted freely with a Velcro strap according to arm thickness.
If your arms are thin and the end of the belt is loose, fold the end in half before fastening.
Once the correct position is found, align the arrow of the Sound Checker toward the direction of the shot and secure it firmly with the belt.
