This putter took more than two years of research, development, robotic testing and 5 fully functioning versions, prior to a full year of testing by PGA touring professionals, before the final production version was ultimately ready to change your game forever.

Defying Convention in Every Detail.

This putter is a brilliant blend of 4 materials, 7070 aluminum, AS370 brass, ultra-high density tungsten and 6061 aircraft aluminum.  Fitted with advanced materials and combined with our ULBP technology the 66 offers a precise feel and playability, never before available in this style of putter. 

It is the first of its genre that performs more beautifully than it looks.

Balance & Center of Gravity Perfection.

The 66 weight redistribution is pure genius.  Nearly 80% of the total head weight has been moved to the perimeter, toe and heel. Mis-hits roll off the face like perfect contact on the sweet spot.

Step out of the past.

See how physics and applied science are the real game changers.

Technology Developed On Tour.

The 66 had to prove itself in competition before we would be satisfied. 2019 saw the prototype 66i move up 77 places, in overall putting, from 80th to 3rd on the PGA Champions Tour. Amateurs, both high and low handicap, are extolling the virtues of this amazing instrument. 

From address, through take away, to impact with the ball…you have never experienced anything like this.

Milled 360C Brass

Brass is a metal alloy made of copper and zinc; the proportions of zinc and copper  in our brass have been customized to create the perfect balance of properties specific to our putting instruments. Over time brass forms a thin protective “patina”, which, unlike steel will not rust. It is a high-density material ideal for putters. 

Milled 7075 Aluminum

7075 is a high strength-to-weight ratio high grade aluminum. It is largely used in aerospace applications where high strength and light weight properties are critical, this alloy is preferred. In our application this alloy allows us to control the center of gravity more perfectly than other alloys.

Milled 6061 Aluminum

6061 Aluminum is, by any measure, a fantastic aluminum alloy. It is a perfect alloy for our faceplate application due to its strength and ability to be anodized, adding a layer of protection against damage. 6061 is typically used in aircraft components.

High Density Tungsten

Tungsten metal (aka wolfram) is a basic element with a density of 19.25 g/cm³, which is comparable to that of uranium and gold. It has a melting point of 3422°C, which is the highest of all the non-alloyed metals. It gets its name from a Swedish phrase meaning ‘heavy stone’, indicative of the metal’s weight and strength.  It is a very expensive metal and it is the most popular metal for men’s wedding rings in America


On mis-hits, up to 1/2″ off center, the Series 66 will experience less than 2% energy loss without directional variance. 

A typical “Answer Style” blade will have 10-20% energy loss, on the same mis-hit, and experience significant directional variance.

No other putter will naturally improve your swing path, your face angle at impact, your head release, your tempo and your speed like a Sacks Parente putter.
