Introducing the ThunderBolt Mark II Putter. A revolutionary putter with moveable and removable weights to alter balance and forgiveness for ultimate feel and accuracy.

Putter Physics

Simply loosen the adjusting screws and set the weights. You can move them up or down, reverse them, or add/remove them.

We'll be adding more weights and styles in the future so you can create your own unique performance putter.


Until now, golfers had to settle for symmetric shaped putters with minimal adjustment capabilities. This requires golfers to adjust their putting stroke to work with their putter.


How about a putter that can adjust on the fly to fit your style of putting? The result is a putter that feels comfortable and effortless to use.

Configure the putter to match your unique putting stroke.

Change the putter's feel and balance for different course conditions

How does it work?

Sliding the weights can instantly adjust putter balance to your needs. From face balanced to toe hang to heal hang.

Or reverse the weights to increase MOI (forgiveness)
