SwingPerfect Golf Carbon Fiber Dual Rail Swing Path Trainer. Every wayward shot has the same root cause: the club never traveled where you thought it did. Two rails. One set. Now the path cannot lie.
 
"Two rails. Every club. No guessing which way your path is going."
"The swing path either stays between the rails — or it doesn't. That's the whole lesson."
"Putting to driver. Five drills. One set. 310g total."
 
1. You think your swing is straight. The rails will tell you the truth. Set the two rails on either side of your ball, lock them in place with the tee pins, and swing. If the club head clips a rail, you have a path problem — and now you know exactly which direction it's going (inside-out clips the outer rail; outside-in clips the inner rail). No slow-motion video. No coach needed. The feedback happens on every swing, in real time. After a few sessions, your body will start to self-correct before you even think about it.
 
2. One set. Five ways to practice. Every club in your bag. Day 1: putting path calibration. Day 3: back/follow-through symmetry with the scale markings. Day 5: iron swing path. Weekend: driver path with the rails spaced wide. The sliding adjustment means the rails fit around any club head — putter to driver. You're not buying a putting-only gadget. You're buying a training system that grows with your game.
 
3. The scale markings are there for a reason — use them. Most golfers have no idea whether their backswing and follow-through are the same length. That asymmetry is one of the most common causes of inconsistent tempo and off-center contact. The ruler markings on the rail surface let you measure both sides of the stroke. Set a backswing length, match the follow-through, practice until they're equal. It's the kind of structured drill that instructors use — and now you can do it independently.
 
4. Works on any surface. Stays where you put it. Indoor mat, outdoor practice green, grass range — the tee-pin holes anchor the rails so they don't slide during your swing. No tape. No weights. Just set it, pin it, and practice. The carbon fiber surface is thin enough that the ball rolls off it cleanly when putting — you're not fighting the tool, you're training with it.
 
5. 85g per rail. It fits in a side pocket. The full set is 310g and stores flat. Roll it into your bag when you head to the range. The carbon fiber won't warp in heat or humidity. This is the training aid you'll actually bring with you — not the one that sits in the garage because it's too heavy or fragile to travel.
 
6. Ball position finally makes sense. Set one rail toward the target, angle the other along your foot line. Now you can see in three dimensions whether the ball is forward enough in your stance, whether your feet are truly parallel to the target, and whether the club face is pointing where you think it is. Five minutes of this setup drill before a round does more for your alignment than a season of guessing.
