Super Sonic X10 Overview: What is This?

January 15, 2018

What is the Super Sonic X10?


You’ve likely heard “lag” described as the secret skill of the pros. You probably know that lag is an effective way to pack extra energy into the golf ball and gain yards on your drive. And if you’ve tried to do it yourself, you are also well aware that the precision timing lag requires does not come easy.

We looked into the Super Sonic X10, a training aid designed specifically to help you master lag and increase swing speed. This aid essentially swings like a driver and gives you instant feedback on your timing. The idea is that this immediate feedback will help you make immediate corrections.

We’ve collected some information for you about how it works and what you stand to get out of it. But first, let’s clarify why this tool exists to begin with.

What Problem is the Super Sonic X10 Solving?

In the most basic terms, the Super Sonic X10 is designed to help you increase your swing speed. It does this primarily by helping you master lag. In case you’re not entirely clear on what “lag” is, here’s a quick primer.

Lag is a technique used by all the pros but only occasionally mastered by amateurs. It refers to the angle between your lead arm and club shaft on the downswing. The theory is that the tighter that angle is, the faster your swing speed will be. You will find a variety of opinions on how to create lag. One common belief is that you should create that tight angle by tucking the trail arm in close to the body, rather than outstretching it on a wide casting motion.

This angle is significant because it influences the motion—and therefore the momentum—of the clubhead. Most amateur golfers hinge their wrists completely at the top of the swing. It is an instinctive attempt to set the wrists at the correct angle for impact. Then, they cast out wide on the downswing too early, releasing all the energy before the clubhead reaches the ball–in  essence, releasing all the lag.

Pro golfers, on the other hand, know to create either a partial hinge or no hinge at the top of the swing. Then, they can create the hinge (i.e. release the clubhead) closer to the moment of impact. This delayed release generates greater clubhead speed at the exact moment they need it.

In other words, lag replaces a wide casting motion with a more whip-like motion.

Lag is not an easy skill to master. It’s all about timing, and mastering that timing proves to be a challenge for many amateur golfers. This is the problem the Super Sonic X10 seeks to solve.


The Design of the Super Sonic X10

The Super Sonic X10 is a training aid that essentially takes the form of a driver, minus the clubhead. It is not intended to be used to strike the ball. Its only functions are to help you master lag and test your swing speed. And because your feedback comes directly from the Super Sonic X10 rather than ball flight, you can practice with this device anywhere, in any season.

The design is very simple. There are two main features.


First, there is the built-in SwingSpeedometer. This is exactly what it sounds like. The speedometer is built into the base of the Super Sonic X10 where the clubhead would be. The speedometer gives you immediate feedback after each swing, reporting your swing speed in miles-per-hour. This feature exists as a way to motivate and challenge yourself. It also allows you to test whether your practice time with the Super Sonic X10 is actually achieving the results you want.

To help you master lag, this training aid also features a SpeedSlider. If you caught our article on the B1 Blue Strike, you’ve seen this feature before. Like the Blue Strike’s Impact Slider, the SpeedSlider helps you time your release through an auditory cue.

The cone-shaped slider sits just below the grip. The moment you release the clubhead, the slider also releases and travels down toward the stopper at the base of the club. When it strikes the stopper, the slider makes a clicking sound. You want that click to happen when you are in impact position. If you hear it earlier, you know you released too early.

What makes the SpeedSlider different from the Impact Slider on the B1 Blue Strike is the added dial. The Super Sonic X10 features a dial at the base of the grip. This dial has ten settings. A higher setting means you need more speed to move the slider. So even once you’ve mastered lag and are getting great speeds at a setting of three, you can still challenge yourself by bumping it up to a four.

How the Super Sonic X10 Promises to Change Your Game

At this point, it’s clear that the Super Sonic X10 is all about gaining swing speed. With regular use, this training aid is designed to help your body learn what optimum speed and lag feel like in your swing. Once you ingrain those habits, you theoretically see the results out on the golf course. Basically, you can figure that for every 1 mile-per-hour increase in your swing speed, you’ll see a gain of about 2.5 driving yards.

The team behind the Super Sonic X10 also claims that training with this product will make you more comfortable increasing your speed. At some point, someone may have warned you against going for speed. Or you may hold back out of instinct. A faster speed can make for a sloppier swing. And we all know that nothing kills the thrill of making a long drive like watching the ball fly 200 yards in the wrong direction.

The Super Sonic X10 claims to improve accuracy at the same time that you’re increasing speed. The release, dictated by the design of the SpeedSlider, is timed to square the clubface for impact.

Ultimately, the Super Sonic X10 promises you will be able to swing faster with confidence.

The Cost of the Super Sonic X10

The current price of the Super Sonic X10 is $119. The purchase includes video lessons featuring Peter Kostis. They send these lessons via email after your purchase and include instructions for the product as well as practice routines.

The Super Sonic X10 comes with a 60-Day money back guarantee… and some very specific promises.

If you practice twenty swings each day with your Super Sonic X10, the company guarantees you will pick up at least 8 mph in your swing speed in two months. (That would be an increase of about 20 driving yards.) If you do not achieve that, you are guaranteed a full refund, no questions asked.

In Short…

The Super Sonic X10 is a training aid designed to help you master lag and increase swing speed.

It has the look of a driver, minus the clubhead.

The Super Sonic X10 features a SwingSpeedometer to give you instant feedback on your swing.

To help you increase speed with a delayed release, it includes a SpeedSlider. The slider is located at the base of the grip and begins sliding toward the bottom of the club at release. You should hear the slider click at the bottom of the club at impact position. If it comes earlier, you know you’ve released too soon.

Our Take

The biggest setback we notice with the Super Sonic X10 is that it needs battery power to work.  Without the battery, you basically have a $100 stick.

Another problem a lot of users seem to have encountered is battery life itself.  When you add the electronics to the equation, you just have another component to worry about breaking.  So while the product itself is pretty valid, many of our readers have been sour on the life of the training aid.

So if you are worried about the product breaking down, our suggestion would be to try the Power Stick instead.  The Power Stick helps golfers increase club head speed and distance, not by swinging harder, but by learning how to swing faster.  And at about $20 less, you can use that extra money on your next tee time to see that extra distance!

You can read our review of the Power Stick for more information, and how mastering lag can help you gain those extra yards you didn’t know you had!

What Are the 3 Most Common Distance Killers for Amateur Golfers?


  1. Hi, I got the speed stik advertised by Bobby Wilson and broke it in 3 months. The concerns I had with it, besides the breaking, were I was using a 5 on it 1 day after I got it, so other than timing it was not going to help me increase my speed. Also the click was tooooooo loud for use inside and I can imagine my neighbors would not like it hear it outside either. How does this product differ from that training aid? Looks the same, except for the speed meter. Thanks, Jim

  2. Hello
    Bought supersonic 10 a month or so back. Worked good for first few day’s, but after that the speed meter stopped working.Thought battery must have finished it’s juice.Went to Batteries Plus and bought new battery, installed it and still speed meter is not working.Other than that it look’s good.

  3. there were no instructions included with the delivery of my recently purchased x10. is something written or available as to how to use or reset the swing speed of the device?

  4. how do i get written instruction on how to use my X10

  5. I feel for sure that when I get the click with the sonic X 10 it is way at the end of my swing in front of me when my hands are about head High.
    It does seem to be helping me get a higher swing speed reading but I don’t know if it helps if it’s not at the impact position. What’s your opinion thank you.

  6. I am getting the click with my sonic X 10 only way past impact position when my hands are almost head high. Is that OK. What’s your opinion thank you.

  7. Sounds like a piece of junk maybe tiger woods might like to use it

  8. I bought the X-10 worked for 2 sessions then quit working. Took apart thinkin g battery dead found out if you wiggle jiggle and hit it a few times it will work for a swing or 2. Piece of junk!

  9. I bought mine online through a Hank Haney video and the link gave me video from Peter Kostis. Once you order, you get more videos from Kostis on how to use it, drills, etc. I think it’s going to help me get through the ball better and I want a few more MPHs of speed. However, I have the same concerns as mentioned above. After just 10 days the second digit on the speedometer has stopped registering. I imagine the other digit might go soon as well. For those of you getting the “click” well after your contact point with where the ball would be, I think that’s a coordination issue with the speed dial setting. With a swing speed around 80 mpg, you should be on a setting of 3. Setting of 2 is good for gentle swings to warm up. If you are around 90 mph, you need to be on setting 4 or 5, I imagine. Great concept…..but we’ll see if the speedometer holds up.

  10. The concept is good, but it has not been perfected yet. Two months ago I bought the Super Sonic X-10 and it worked for two weeks. I called and they sent me a new one. That last about two weeks also. They wanted to give me another one but I took the money instead. If it would only work for the long haul, it would be a miracle golf product. It is not the battery, because I put in a new battery and it still did not tell me the MPH. PLease let me know when you get the bugs out because it is a great idea and i did gain 20 yards extra distance using it for the short duration I owned one.

  11. I had mine for less than 2 months and the display quit. Will return it unless there is a fix.

  12. Brought the Super Sonic X-10 in January. It arrived with a dead battery. I called customer service and was told that this was a common problem. A new one was sent with a new battery which lasted for about a week. The company should recognize this problem and simply issue refunds to all purchasers. Instead it appears that Golf US is now selling a “new” version of the speed stick. I am surprised that Hank Haney and other golf pros continue to endorse this product.

  13. Their customer service is excellent. I know because I’ve now sent back 3 of the speed sticks which each
    worked for about a week. My fourth is currently on the way. Great product concept. Now if they could only
    make some that actually work. I’m amazed that two fellows with the fine reputations of Haney and Kostis
    continue to endorse the product.

  14. Thanks to all people who posted above. Sounds like poor quality and I’ve decided not to buy. The Speed Stik threw off my timing, and the Orange Whip aggravated my shoulder. The best thing I’ve found for increasing swing speed is practice swings while holding the head end of the driver and listening for the “whoosh” at impact.

  15. I bought one and the speedometer went out after a week piece of junk.

  16. The Shaft ON My X-10 Is Chipping Apart, I Have Photos. But Who Do I call Or Where Do I Return It ???

  17. Thanks for the comment Tony. We are not affiliated with this product, so I would suggest checking their website to see if there is a number or email for customer support. Best of luck!

  18. The battery on my x-10 went dead after one day. I couldn’t get the screws out that hold the battery. An Allen wrench got one of them, but the other two are stuck. Not very happy.

  19. Has this product lasted more than 2 weeks for anyone ?

  20. The speed slider worked the first time and hasn’t worked since. I can’t get it to release, even when swinging savagely.
    I am hoping to return this for a full refund.

  21. Can I Get A Phone # And Talk To Customer Service Please

  22. I’ve had mine for about 3 weeks, and to date, no problems. I asked the company if this was a new version of the product, and they said yes, they made some improvements over the winter to protect the electronics housing to prevent the lag slider from banging directly into it (there is a plastic wrap of some sorts at the bottom of the speedometer’s housing that indeed, absorbs the blow from the lag slider. So, perhaps the problems listed here have been somewhat addressed???

    The product DOES work. I’ve gone from 88 MPH to 96 MPH in two weeks. The key is the training protocol…the Kostis videos on the website. Bottomline, it’s overspeed training…the resistance dial is providing a light, medium, heavy resistance. “The 5s” and the “Time Saver Workout” are the 2 primary protocols. I use the Time Saver in combination w/ my homemade Superspeed Sticks Level 1 protocol 3x weekly. It’s working….the trick is gaining the confidence to really RIP IT when hitting balls or playing, and having the confidence that the more aggressive swing will hold up.

  23. Hi Tony, we are not actually affiliated with this product, nor do we sell it. We just did a review of the product itself.

    Here is a link to their customer service page, which also has a number for contacting:

    Best of luck!

  24. not working no display and allready changed battery

  25. How do you change the Sonic X10’s battery?

  26. Bought my first one about 9 months ago, display wouldn’t work, I sent it back & they shipped me a new one, stated the originals had a few “flaws” . I finally purchased the special T-10 Srewdriver typewrench torque wrench you need to replace the batteries, about $6 bucks. It worked fine for a few months , but now the display won’t work. It’s a great product when it’s working. I’m trying to see if they’ll replace this one as well, if not, I’m certainly never going to order from this company again.

  27. Thanks for the comment Ted! We have heard similar battery issues with other readers who purchased the club. If you are still looking for a swing speed trainer, we recommend the Power Stick. It doesn’t require batteries, it has a formed grip to help you hold it properly, and you still get the audible feedback to help you work on your lag, as well as adjustable speed settings (and no wrenches necessary!). Here is a link to their website:

    Thanks for reading!

  28. My x10 worked great at the beginning but now when I put in a new battery it only lasts for about one hour. I’ve sent three e mails to the company but they don’t even acknowledge or reply to my messages.
