From the inside out
The Graff smart golf ball is embedded with patented electronics that capture every shot you hit — on the course or at home with a net. Real data. Real improvement. Finally.
The Process
The Graff system is the only tool that turns every shot you hit — whether on the course or into a backyard net — into real, actionable intelligence.
Use the Graff smart golf ball exactly like any other ball — on the course or off it using a net. The patented electronics inside capture data on every single shot you hit. No extra devices. No clunky setup. Just play.
After each session, connect via Bluetooth and sync to the Graff app. View detailed analytics for every shot — velocity, launch angle, spin rate, distance, hang time, and more. The more you play, the more accurate your data becomes.
Your data drives a personalized improvement plan. Access curated drills matched to your actual weaknesses — not generic tips. Know what you did right and, more importantly, what you did wrong and exactly how to fix it.
Shot Data
The Graff smart ball is embedded with a unique, proprietary chip that records ball speed, launch angle, shot distance, spin rate, hang time, and spin direction — data points currently only available to professionals with $20,000+ launch monitors.
Connect to the Graff app via Bluetooth, and you have a personal launch monitor that fits in your bag. Use it on the fairway or set up a net at home. The data goes where you go.
The Smart Ball
All the technology is packed inside a regulation golf ball. No external trackers, no sensors to attach. Just hit it.
Every Graff smart ball is Bluetooth-enabled for syncing, charging, and location tracking. Find your ball up to 300 feet away — even in the rough, in a bunker, or under leaves. Never lose a ball again.
Shot data appears in the app on every shot you hit, instantly. No waiting. No manual entry. Just swing, and see your velocity, angle, spin, and distance appear in real-time on your phone.
Track your round score with GPS course data from over 36,000 courses worldwide. Automatic hole-by-hole scorecards synced to your shot data — giving you the full picture of every round, not just practice sessions.
You don't need to be on a golf course to get better. Set up a net anywhere and use Graff as your own personal launch monitor. The same shot data, the same improvement programs — whenever you want to practice.
Course Integration
The Graff app tracks your round score with GPS course data from over 36,000 courses worldwide. Play your home course or travel anywhere — your data travels with you and builds into a complete picture of your game over time.
Every round adds to your analytics history. The more you play, the smarter your improvement plan becomes — automatically calibrating to your actual performance patterns, not generic golf tips.

What Golfers Say
"I've been playing for 20 years and never truly understood my shot data until Graff. After two months, I dropped my handicap by 4 strokes. The improvement plans are incredibly specific — not generic advice. This is the future of golf training."
"The net practice feature changed everything. I live in Chicago — I can't play in winter. Now I set up a net in my garage and get the same data I'd get on the course. My driver swing has never been more consistent. Worth every penny."
"The Bluetooth locator alone is worth the price. I stopped losing $5 Pro V1s on every round. But what really sold me is how the app connected my 7-iron spin rate problems directly to my ball-striking drill plan. This is a professional tool."
