The More Pars Double Trouble Ball takes the guesswork out of putting. It helps to ensure that your putter’s face is perfectly square at the point of impact AND that you are maintaining the putter’s true loft (not adding or taking away loft). Plus, it provides clear feedback of where you start your ball (on the target line, too left or too right). 

Use the Double Trouble ball that is connected to test your skills. It should roll straight end over end. If it spins left your face was closed. If it spins right, your face was open. If it jumps and hops, you either had too much or too little loft.

With the Duo Gate you Can Improve:

• Square Face at Impact
  
• Contact (loft)
  
• Aim & Apex
  
• Loft at Impact
