Sacks Parente Golf (SPG) Saves Grams and Saves Shots by Shifting to its Newly Patented Magnesium Face Technology

SPG’s Series 66mg putter leads the way in the move from an aluminum insert to the new magnesium face technology for better feel and accuracy

Camarillo, CA., January 10, 2023 – Sacks Parente Golf (SPG) is continuing its relentless pursuit of helping golfers make more putts by introducing a crucial gram-saving putter insert technology. Starting with the company’s Series 66mg Anser-style putter, SPG is moving from its original aluminum insert and replacing it with SPG’s new patented magnesium face technology – a patent that SPG secured earlier this year.

Why the Switch from Aluminum to Magnesium Inserts?

The inspiration behind the change originated from SPG’s obsession with saving and redistributing weight to places that benefit the golfer the most. “Everything we do is about saving weight and redistributing it to the benefit of the golfer,” said Steve Sacks, Co-founder of SPG. “Saving grams is what we do, and I believe we are better at that kind of engineering than anybody.” 

SPG’s patented magnesium face technology is 35% lighter than aluminum, allowing SPG engineers to take 4-5 grams out of the middle of the club and place it in the heel and toe – all to deliver a more stable Anser-style putter.  

“Aluminum weighs 2.7 grams per cubic centimeters, whereby magnesium weighs 1.74 grams per cubic centimeters,” said Sacks. “That’s five times lighter than steel. We tried all kinds of materials including metals, ceramics, different steels in different configurations, and we found that magnesium provides a better feel than aluminum. Our patented magnesium face insert will keep the ball online even with a mishit of up to ½” to the toe or the heel from center. This technology, that only SPG can deliver, provides the ultimate in lightweight and performance.”

Additional Technologies and Patents in the Series 66mg Putter

Ultra-Low Balance Point (ULBP)

The Series 66mg putter, as do all SPG putting instruments, incorporates an additional SPG patent, the Ultra-low Balance Point (ULBP) technology, which means that SPG engineers have taken weight out of the shaft and grip and centralized most of the weight in the head. With a lighter shaft and grip, golfers can feel the gravity in the head weight enabling a natural stroke, good tempo, toe release and neutral acceleration at point of impact – all resulting in a consistent putting stroke.

CNC Milled

The Series 66mg putter is CNC milled from five different metals, all formulated by SPG engineers to deliver feel, roll and distance control so lag putts become second nature and three-putts a thing of the past.

The SPG Series 66mg putter is available now for $479.99 on
