Just wrapped a Stack Wedge session and tracked every shot with Mevo+. Check out the carry comparisons. Stack Wedge powered by the Stack Radar has obvious limitations, but what a great combo to practice distance control.

There’s a lot of golf products out there but @TheStackSystem continues to shine!

Speed, wedges, putting, and now strokes gained data from your round! I can’t wait to log more rounds in Stack Stats!

Finished STACK Foundation Today. Pretty good improvement for a 76 year old I think!!! Thanks @SashoMackenzie @Guidry_Golf_Fit and Mach3 Speed Training Tools. On now to STACK Progress Check next week, and then the NEXT STACK PROGRAM. #220yardsiscoming

There's a lot of hype around the idea of forgiveness, which is a benefit, but it's a secondary benefit.

Wrote about it here but as @SashoMacKenzie explains, off-center hits aren't usually the reason why you miss putts.

It's face angle.

Needed to work on my wedges with @TheStackSystem before my qualifier

Feeling pretty, pretty, pretty good!

@OdinStrTho We are working on having Learning Library speed tips play during set breaks.

Sweet insight into how some of our most active Pro Stackers are seeing their bat speed gains translate to on field performance 💪

Welcome to the 10K Club, Jay!

The 10K Club recognizes Stackers who have accumulated 10,000+ Stack swings - a milestone that reflects commitment and consistency over time.

To celebrate the achievement, members receive a set of gold Stack weights as a tribute to the work they've put in along the way.

Congratulations, Jay.

Small enough to fit in your pocket. Smart enough to change the way you practice.

The Stack Radar gives you instant club speed feedback on every swing. Use it during speed training sessions, on the range, or even when you're hitting balls on the course.

When you can measure speed instantly, every swing becomes more intentional.

Pair it with TheStack App in Wedge Mode and it gets even smarter.

The app calls out target distances and scores your shots in real time, turning wedge practice into a data-driven, gamified training session designed to sharpen distance control from inside 150 yards.

🔥Train speed.
🎯Dial in your wedges.
🧠Practice smarter with The Stack Radar.

@Fit_For_Golf @ColinSh86041284 Mike is correct. I look at this type of data all the time. Most golfers or instructors would not find it helpful. Interesting, but not particularly actionable.

I’m getting older, but I’m not old yet. Losing speed is a still a choice and I’ve been making it for too long.

Went to work.

Y’all can call me Celine Dion because it’s all coming back.

I’m not ready for 12.5° senior flex (yet).

[Michael Finney @mfinneygolf]

Looking forward to it…
