The laser from Butch can also be adjusted to be focused on the sweet spot.
I have this item, but I haven't really ever used it, yet.
Just for the following question, can we ignore the fact that the laser doesn't start from PP#3.
But, as far as it focusing on the sweet spot, it actually is focused just in front of the leading edge of the club. So, it's actually about an inch or so in FRONT of the sweetspot.
If any laser on a golf club was to point at the sweetspot of the clubhead/face, then it would just shine onto the sweetspot and not on to the ground (target line). Does this make any difference? Is it okay for the laser to be pointing in front of the leading edge?
Given the limitations of the laser trainer, as long as the laser beam lies in the same Plane as the Sweetspot, you'll be all right.
However, never forget that your ultimate goal is to educate The Hands (per 5-0 and 6-G-0) to execute the Three Imperatives -- including the Right Forearm / #3 Pressure Point Plane Line Tracing we are discussing here -- through the Three Stations (Address, Top, and Finish per 12-3). This does not require a Shafted Club -- laser or otherwise -- and in fact, for reasons I've stated in previous posts, the presence of a shaft can be detrimental. Again, per 5-0, the Hands must learn to Monitor only themselves, not the Clubhead or Body.
Here's a recommended training program for Plane Line Tracing:
1. Begin with a shaftless device, e.g., a flashlight with the lens at the #3 Pressure Point. Find any floor or driveway (but remember, neighbors will talk!) and Trace every straight Plane Line you can find.
2. Once a good Tracing motion has been established, work with a Headless Shaft -- that eliminates any "sweetspot" pointing problems! -- and Trace away. In fact, you might want to use two headless Shafts in your training: the first with the Shaft cut off at the bottom of the Grip (to enable you to assume your Grip as you Trace while retaining total focus on the Hands and what they are doing; and the second with the Shaft cut at the Hosel (for direct Plane Line pointing). And don't forget to include some closed-eyes training (per 5-0 and 3-B).
3. Then take it to the range and Monitor the Clubhead through the Impact Interval in actual Stroke Execution. Few golfers actually do this: Most suffer from an incurable case of DownStroke Blackout! As a cure, per 8-0 (#3), visualize the path of the Clubhead through and beyond Impact. Then. make sure you actually see the proper blur of the Clubhead passage through Release. Look, Look, Look per 3-B. This is a precision system dependent on precision execution!
Now, do the great Players do this? You bet they do! They know exactly what is happening during the Moment of Truth. One of Byron Nelson's most important Swing keys was to "watch the Clubhead flatten out at Impact." Johnny Miller says the same thing, only he refers to the process as Brushing. Specifically Brush-Brush, back and through. Lee Trevino has the mental image of the Clubface going through four balls -- not just one -- during the Impact Interval.
We call it Plane Line Tracing.
But we're all talking about the same thing: Controlling the Clubhead Line-of-Flight (2-N-0) through Impact. It is best done with Educated Hands controlling the entire operation, and they are best educated -- certainly in the early learning stages -- without the distraction of a physical shaft...whether that shaft be on a laser trainer or otherwise.
