thePuttGPT lets you assemble up to 5 Putting Trainers, each using your preferred golf balls—so you get the exact look and feel you’ll see on the course. 

The two-ball system forces a square strike: open or close your face more than 1°, and the balls spin offline instantly.

It's addictive, challenging, and the fastest way to calibrate your stroke and build putting confidence that holds up under pressure.

Assembling thePuttGPT 

1. Grab two preferred golf balls.
2. Take one center connector and insert it into the alignment tool.
3. Peel both Watson Golf stickers off each side of the center connector.
4. Place your first golf ball in the assembly channel and align it to your preference. 
5. Take the alignment tool and slide it into the assembly channel. 
6. Insert your second golf ball into the assembly channel to match the first. 
7. Press and hold firmly for 5 seconds. 

Practicing With thePuttGPT

1. Place your two-ball golf putting trainer on any flat surface. 
2. Try to consistently roll the golf putting trainer in tandem (rolling it perfectly straight is virtually impossible, so getting the balls rolling together is your goal!)
3. If you strike the two-ball system with your putter face more than 1° closed or 1° open, you will send the balls spinning offline.
