Ball striking wins U.S. Opens.
Narrow fairways. Punishing rough. Firm greens. Every year, the U.S. Open strips golf back to its essentials. Under the toughest conditions in the game, one skill repeatedly rises to the top: ball striking.
It's no accident. The U.S. Open rewards control of the ball from tee to green above all else — which is why, year after year, it's won by the purest strikers in the game.
To mark golf's ultimate test, Dan Frost has put together three training aids, each developing one essential of elite ball striking.
The System · Set, width, lag
Three tools. One repeatable strike.
SET — Sure-Set
Builds the fundamentals of a sound backswing and transition — where every quality strike begins. You'll feel the club set in the right place going back, so the downswing has something solid to fire from.
WIDTH — Tour-Feel
The No.1 swing-width trainer on Tour. A radius trainer that holds your arc wide and repeatable, so the low point arrives in the same place, swing after swing.
LAG — Lag-Pro
Trains lag and forward shaft lean into impact — the essential that compresses the ball. You'll feel the hands lead the clubhead through the strike, the way every clean iron player does.
Practice The Way The Best Players Do.
Watch any Tour player warm up and you'll see the same thing — they're not running a mental checklist. They're feeling their way into the swing. The System trains the same way: the set, the lag, the width, built as sensations your body retains. Fewer swing thoughts. More feel that holds when the round gets tight.
What's in the System

One price.
Sure-Set

A Note from the Coach
“The U.S. Open is the truest test of ball striking in the game — and it's won, every year, by the players who strike it best under the most pressure.”
I built these three aids around the three things that strike depends on: where you set the club, how wide and repeatable your arc stays and how you hold your lag into impact. Not positions to chase. Sensations your body learns and keeps — the same ones the best ball-strikers in the world already own.
The feedback you'll feel on the first ball. The improvement, you'll earn — because you trained it. That's the only kind that lasts.
The Knowledge Centre
Your System. Your Coach.
Your System comes with a coach. The Sure-Golf Knowledge Centre gives you 100+ structured video lessons from Dan Frost - so every range session and every spare ten minutes turns into deliberate practice. Each of the three aids has its own path, from first setup to advanced skill.

Game Chaning
The sure set is really helping me improve my takeaway and I have seen my shot shape change slightly already. Really positive stuff. The video lesson's sent with the sureset are also so helpful ⛳️

This is a must have for golfers struggling with wrist extension through impact
This is a must have for golfers struggling with wrist extension through the ball. I've been working on this for years and just didn't have the feel, this improved me more in two sessions versus my work over the past two years, great product!
Tour-Feel
Everything I have been missing in my golf swing! I wish I would've ordered it sooner instead of wait till the end of the season.
Tour-Feel
Wasn't too sure this device would have any real applications but after watching the You Tube videos and going to the range I learned what the real feel was with this training aid. This is a must for anyone looking to improve their ball striking.
FAQs
All three aids — Sure-Set, Tour-Feel and Lag-Pro - shipped together, plus full Knowledge Centre access for each.
These aren't built around one swing model. They train the fundamentals every quality ball-striker shares - the set, the width, the lag - so the work carries to your swing, whatever it looks like. It's the standard the Tour trains to.
Then you've built the foundation. This is the rest of the strike - the three fundamentals that turn a sound swing into a consistent one.
