7 Golf Training Aids to Fix a Slice Fast

Is there anything more frustrating than a nasty slice off the tee?

A slice not only costs you a lot of distance but also takes you out of position, often leading to higher scores and missed opportunities. Which can turn to hitting 3-wood to “play it safe” which is actually horrible advice that might be holding you back. 

The good news? You can fix your slice—and fast. Today, I’ll share seven golf training aids to fix your slice so you can hit it straighter and longer. When you fix this issue, you’ll step up to the tee box with confidence and consistency. 

7 Golf Training Aids to Cure Your Slice

Before diving into the best training aids for a slice, let’s address one of the biggest causes of a slice—your grip. If your hands aren’t positioned correctly on the club, it’s nearly impossible to square the clubface at impact, leading to that dreaded banana ball.

One of the simplest and most effective ways to improve your grip is by using a grip trainer that replaces the grip on an old club. This ensures your hands are in the proper position every time you take a swing, reinforcing muscle memory so you don’t have to think about it on the course. A neutral to strong grip helps eliminate an open clubface at impact, which is a major contributor to slicing

Spend the $10, attach it to an old club, and swing it regularly in practice or at home. This is one of the best budget training aids and will have a ripple effect through your bag. Now, let’s review some others to help straighten out your ball flight. 

1. WhyGolf Alignment Discs 

If you’re fighting a slice, I bet you’re using alignment sticks for various drills to fix the issue. This is where the WhyGolf Alignment Discs come into play… because angles matter.

Unlike simply sticking alignment rods in the ground and hoping for the best, these discs allow you to adjust for six different angles (from 45 degrees to vertical). This makes them incredibly versatile for working on key swing changes, whether you’re fixing a slice, a hook, or fine-tuning your swing plane.

How to Use Them to Fix a Slice

If you tend to slice, you need to set them up to promote a more in to out swing path. Here’s how: 

1. Position the disc about ¾ of a club length away from the ball.
2. Adjust the foam rod to one of the three settings (50, 58, or 65 degrees) based on the club you’re using. For a 7-iron, the middle setting is ideal.
3. On your backswing, the goal is to move over the rod to encourage a more outside takeaway.
4. On your downswing, swing under the rod to promote an inside-to-out club path—helping straighten out your shots or even adding a slight draw.

The closer the disc is placed to your target line, the more challenging (and effective) the drill becomes. With WhyGolf Alignment Discs, your angles stay the same every session—giving you consistent, structured practice that translates to real improvement on the course. 

Plus, you can use them even if you’re hitting off mats and/or practicing at the simulator. If you’re serious about eliminating your slice, this is one of the best tools to fine-tune your setup, swing path, and overall ball flight.

2. Eyeline Golf Speed Trap

If you're dealing with a slice, hook, or inconsistent ball striking, the EyeLine Speed Trap 2.0 is an excellent tool to correct your swing path and improve ball contact. This training aid provides instant feedback by using adjustable foam rods—if you make a poor swing, you’ll hit the rods, immediately revealing whether your club is off-plane.

By working with the Speed Trap, you'll learn to develop a more neutral or inside-out swing, which is key to eliminating that weak, spinning slice. Whether you're practicing with irons or driver, it helps create a more efficient swing path, leading to straighter, more powerful shots.

The best part? It’s incredibly easy to use, whether you’re practicing on the range or at home. If you’re serious about improving consistency and ball striking, the Speed Trap 2.0 is one of the best tools for training better clubface control, path awareness, and cleaner contact.

3. Tour Striker Smart Ball

One of the biggest contributors to a slice is excessive hand and wrist movement during the swing. If your arms and body aren’t working together, it’s tough to square the clubface at impact. That’s why so many top players use the Tour Striker Smart Ball to promote a more synchronized, efficient swing.

This inflatable ball sits between your forearms and forces you to maintain proper connection throughout your swing. By eliminating excess wrist action and hand separation, it encourages better rotation, improved sequencing, and a more stable clubface at impact—key elements for reducing a slice.

It’s trusted by PGA Tour players, including Justin Rose and countless others. This slice fixing training aid is lightweight, easy to store in your bag, and works for both full swings and short game practice.

4. WhyGolf Arm Alarm

Another training aid to keep your arms connected similar to the Tour Striker Smart Ball is the WhyGolf Arm Alarm. It is also designed to fix disconnection by providing instant auditory feedback when your arms separate too much during the swing.

Unlike other training aids that physically force your arms together (but stop helping the moment you remove them), the Arm Alarm trains your brain and body to move correctly on their own. When used correctly, it helps eliminate early extension, flipping at impact, and poor wrist mechanics, leading to a more stable and powerful release.

If you struggle with a cupped wrist (which leads to a slice), flying elbows, or inconsistent ball striking, this tool can make a huge impact on your swing mechanics. Compared to the Tour Striker Smart Ball, the Arm Alarm provides superior auditory feedback, helping you recognize and correct swing faults faster.

It’s lightweight, adjustable, and easy to use in various drills, this training aid is perfect if you’re looking to build a more connected and repeatable swing—without having to think about it mid-round.

5. HackMotion Wrist Sensor 

If you’re serious about fixing your slice and improving your swing mechanics, the HackMotion Wrist Sensor is one of the most advanced tools available. This high-tech training aid provides real-time data on wrist angles, allowing you to measure and fine-tune your wrist position throughout the swing. 

Since wrist mechanics play a major role in clubface control, this device helps you develop a more stable, consistent release, reducing slices and weak shots. Compared to other wrist training aids, like The Hanger, the HackMotion delivers precise, measurable feedback instead of just forcing a position. 

The ability to track your wrist angles and compare them to tour player benchmarks gives you a level of analysis that’s hard to find in other training aids. However, because of its higher price point and the amount of data it provides, it can take some time for golfers to fully understand how to use it effectively.

6. WhyGolf Alignment Mirror  

Your slice might also be an alignment issue (once again, sadly speaking from experience). If you set up close and right of the target, it’s easy to hit a lot of pull slices. 

Over the years, I’ve tested everything from alignment sticks to Tour Aim, but nothing has been more effective than the WhyGolf Alignment Mirror. Unlike traditional aids that only focus on feet alignment, this mirror provides real-time feedback on shoulder positioning, helping ensure everything is square to the target. 

I used to “cross my lines” where my feet were right, but my shoulders were open, leading to a nasty slice. The Alignment Mirror works on the range or in the simulator, making it a staple in my practice routine.  

If you’re serious about improving your setup, this beats alignment sticks every time. You can also check out my full review of this training aid now, or watch the YouTube video below. 

7. Draw Board 

The final training aid to help straighten your ball flight is The Draw Board. This simple tool makes it easy to feel a more in to out swing to hit a draw (or at least straighter ball flight).

Unlike traditional alignment aids, this board provides instant visual and physical feedback to help you feel the correct motion. Positioning it properly forces you to swing from the inside while keeping the clubface square, which is key to eliminating a slice and even developing a slight draw.  

Like the Eyeline Speed Trap, it works with any club in the bag, whether you're fixing your driver path or working on iron consistency. If you tend to cut across the ball and struggle with accuracy, the Draw Board is one of the simplest yet most effective tools to straighten out your shots and add effortless power.

Closing Thoughts

A slice is frustrating but know that you can fix it sooner than later. Start by addressing your setup, specifically your grip and aim. Then double-check your adjustable equipment is in a draw setting to help offset any swing issues. 

Once your equipment and setup is dialed in, use one or two of these training aids to improve your swing. They will help your arms stay connected, improve your takeaway, and groove a more into out swing path.
