A putting stroke training device has two adjustable arms, each joined to an elevated
arch at the "closed end" of the device. Preferably, the elevated arch is of sufficient
dimensions to allow a golf ball to travel underneath and through the arch. Each
arm may be connected to the elevated arch by a wing nut and screw which can be
locked down to set each arm at adjustable angles. A guide ball is affixed to the
opposite end of each arm at its "open end." One of the arms is also connected to
a vertical marker which shows the user where the golf ball is in the user's stance.
The arms may be rotated to open the device to accommodate the width of a putter
swinging through the distance between each guide ball on the open ends of the arms.
A method of using the device is also included.
