Newton Golf has taken a circuitous path to get where it is today. Newton’s predecessor company, Sacks Parente, made a splash with their wildly different approach to putter technology and design. It featured what they call Ultra Low Balance Point technology that primarily centered on unique graphite putter shafts and grips. In a quest to control the quality of their most important technology, Sacks Parente purchased a graphite shaft manufacturing company in 2022. While the assumption is that the company took this route to improve their putters, the reality is that it also allowed them to evolve into a company that produces high end metal wood shafts under the Newton Golf brand. Late in 2024, we learned Sacks Parente was transitioning their entire business under the new name Newton Golf, a Sacks Parente Company.

While the history lesson may be a little tedious, it’s important to convey to our readers, because we recently saw the introduction of Newton Golf’s new putter line, Gravity Putters. While these putters are newly branded, it’s worth knowing that their roots lie in the Sacks Parente technology that changed the putting game. While there are some visual differences that will be immediately noticeable to Sacks Parente fans, the basic premise of how the company believes their offerings will make you a better putter remain the same. Let’s dive into what Gravity putters are all about and then we’ll explore the models they are making available.
Ultra Low Balance Point and CG Technology

ULBP is where it all begins for Gravity Putters, and the Gravity name illustrates this fact perfectly. Simply explained, ULBP means that the balance point of Gravity Putters is below five inches from the sole of the putter, far down the shaft. This promotes an unimpeded pendulum stroke that allows the head the stay square and release at impact, ensuring putts stay on line and that speed control maintains consistency. How does Newton accomplish this? Through a combination of their proprietary shafts and grips. The grips range from 28.5g to 33g in weight, which is about 1/3 the weight of a standard putter grip. Manufacturing a useable putter grip this light is no small feat, relying on Newton’s NANO-cellular technology.

In addition to ULBP, Newton utilizes a forward-positioned center of gravity in their putter heads. While we are so used to golf clubs and putters that utilize a CG that is placed far in the back of the head, there is a strong case to be made that positioning more mass close to where impact occurs positively affects a putter’s ability to produce a consistent roll and reduce sidespin (and the resulting offline misses) that occurs from off-center strikes.
Even with a forward CG, Newton manages to pack their putters with very high MOI, which they say reduces twisting of the head and energy loss with off-center strikes. While a typical putter may lose 10-20% of its energy with a small miss, Gravity putters can lose as little as 2%, which could easily be the difference between a made or missed putt.
ULBP in Action

While we didn’t find an instant connection with each of the five heads in the Gravity line (which should be expected), with the right head and hosel combination it can be downright magical. It’s almost a sensation that must be felt to be understood, but we’ll do our best to explain. Before we go too far, it’s worth noting that our first impressions with these extremely unique putters weren’t exactly wonderful. In hand, the lightness of the putters is very evident. The shaft is different. The grip is very different. These are just different than any other putter you’ll ever hold, and humans can shy away from change. We’re saying this in the hopes that we can convey how much our perception changed when we put them to work.

We found that ULBP, with the right putter head, functioned exactly as described. Again, it’s hard to put into words, but in Gravity’s marketing material they mention the putters’ ability to create a natural pendulum motion. With the putter behind the ball at address, a very simple turn of the shoulders was all it took to start the stroke. We experienced an almost instant elimination of the jerky takeaway that can hamper the chances of making a smooth stroke. In addition, a simple forward rock of the shoulders was all it took to bring the putter to the ball. The less we thought about the putting stroke, the better the technology seemed to work. No manipulation seemed to be required to deliver a square face at impact, leaving us to focus more on the target and less on the process.
You have to try it. There’s no better way to understand the sensation, and it’s a sensation everybody should feel at least once. Will it be right for everybody? Probably not, but it’s worth taking some putts to find out.
The DRAC

The DRAC is Newton Golf’s take on the extremely popular fanged mallet shape. It features a milled face and is constructed of 6061 Aluminum and 100 grams of tungsten weight that you can easily see is positioned forward in the head. This is a head that Sacks Parente fans should be familiar with, albeit with new branding. The aesthetic choices are very bold and lean on the “vampire” theme that the fangs inherently remind us of. If anything, we think this design would be even more popular without this slight campiness, but we found many random golfers immediately gravitated towards the familiarly shaped DRAC.

Even with its aluminum construction, the DRAC managed to produce a solid, low pitched sound at impact. We won’t call it soft, but the milling does a great job at making this a pleasant feeling putter. Speed control and direction were reasonably good, but it wasn’t our absolute favorite due to the occasional two-way miss.
The DRAC is available from 32” to 36” with choice of grip shape and either a center shaft, plumbers, or flow neck. It’s priced at $450.
PRISM

The PRISM is different. There’s really no other way to put it. It resembles the single-striped Sacks Parente Series 54 but features weighting changes to move the center of gravity even more forward. This is high MOI mallet that gives incredible confidence that you’re aligned correctly and will produce a stable face at impact.

Like the DRAC, The PRISM is crafted of 6061 aluminum but only has an additional 50g of tungsten. It feels stable and nimble in hand for such a large head. We found it to be the softest feeling putter in the Gravity line, producing a soft, low-pitched click at impact. Unfortunately, we just didn’t click with the PRISM, finding issues with our directional dispersion. However, it excelled at speed control. Keep in mind that individual results aren’t an indicator of the PRISM’s quality. Rather, it was likely a fitting issue or personal preference that left us enjoying other options more.
The PRISM is priced at $450 and is available from 32” to 36” with a center shafted hosel.
The DEUCE

The all-new DEUCE is a classic doublewide blade that we couldn’t help but fall in love with. It’s constructed of precision milled 1018 carbon and lacks the supplementary tungsten weighting seen in the larger Gravity mallets. A simple red alignment aid on the flange and its square lines made the DEUCE extremely easy to align at address. It wasn’t PRISM soft, but it was certainly pleasant feeling on both center and off-center impacts.

On a personal level, the DEUCE seemed to embody everything we loved about ULBP. It felt almost like it was floating at address and was extremely easy to putt with. The more we let the putter do the work, but better the results seemed to be. Over and over again the DEUCE proved to be the most consistent Gravity putter in terms of putts made, dispersion, and speed control. Our only real complaint doesn’t have anything to do with the putter itself. Unfortunately, the doublewide head doesn’t really fit well into the supplied headcover, making it a bit of a pain to get in and out.
Priced at $450, the DEUCE is available from 32” to 36” with a center shafted hosel and choice of flat, round, or pistol grip.
The DUKE

Named for Ken Duke, who uses it on the Champions Tour, the DUKE is a classically shaped half mallet with a flow neck hosel positioned at the heel. It’s milled of 1018 carbon steel with tungsten weighting and offers the comfort of a familiar shape that still has all the Gravity technology packed into it. Straying from a classic looking design, the tungsten weights are actually inserted into the milled face, bordering the center impact area. Unfortunately, we found this impacted feel to some extent. Center impacts were a bit sharper than with the DRAC, PRISM, and DEUCE, and off-center impacts had a higher pitched tone to them.

As one of two heel-shafted Gravity putters we tested, the first thing we noticed was the DUKE’s more active toe and rotation through the stroke. For many people this will be a comfortable and desired feeling, but it did stand out from the center shafted putters. The look at address was fantastic, with the flow neck and smooth bumpers drawing the eyes in. Even with the substantially different feel through the stroke, we found impressive success across all facets with the DUKE. It’s certainly worth a look if you demand a classic look, but still want to take advantage of the ULBP technology.

The DUKE is available from 32” to 36” at $450.
The CLASSIC

The aptly named CLASSIC is Newton’s nod to the anser-style blade putter. It features a newly designed hosel and is milled from 1018 carbon steel without additional tungsten weighting. This is a look that has stood the test of time, and we expect most who pick up the CLASSIC will enjoy its shape at address. Unfortunately, we felt the CLASSIC didn’t quite measure up to the rest of the Gravity line when it came to feel. The sound at all impact points was a bit higher pitched and stood out from the group.

Like the DUKE, the CLASSIC seemed to produce more face rotation through the stroke, which many golfers will find instant success with. Even for a smaller blade design, we found it to be very forgiving off-center and it was easy to control speed.
At $450, the CLASSIC comes in lengths ranging from 32” to 36” and three different grip options.

It’s a great article, I am having a hard time getting over the visuals though.
Still one of my early THP memories is Jb using a super light putting instrument. I think I like the weight, but I would need a lot of time between them to really decide.
There is something to be said about change just for the sake of change, but I hope these find their way into a bunch of bags to hear more. I would be very interested, especially since it seems like the same stroke as with another putter is going to give you a bit more distance with these if I am understanding correctly.
The more I read about it, the more interested I am in the Deuce. The look just “looks right” to me.
That is a really good take on the #7 shape
Interesting putter tech and great article.
Thanks for reading all.
Seriously, if I’d love to get something like 10 people together with all these putters to see the reactions.

Best for me by a long shot.
Good read. I have rolled the Sacks Parente putters at Club Champion a few times and always thought they swing well. I have one friend who has one and he putts well with it. He is a bit of a club junkie and the putter has been in the bag for 4 years so it definitely works for him.
Great review [USER=1193]@Hawk[/USER]. Sure wish True Spec Golf had these has an option because I’d love to try them out
Drac is a great club name.. lol.
The heads look good. The necks are a little odd looking to me.

Four years is a really long time for anybody. What model does he have?
ULBP has me intrigued. Would love to give the Drac and the Duece a try. Personally don’t really care for the Prism and the wide alignment line. Very curious about the feel of these after putting for a few years with a putter that I was cut to with counter balance weight placed 5” deep in butt end of shaft.

Great article [USER=1193]@Hawk[/USER] and interesting that you noted the less than desirable feel of the putters before putting them to work. I realize you said they are different than anything else, but is there any one thing you can put your finger on that makes it that way? Or is it just a completely different feeling while holding?
The “deuce” is where my head immediately goes as I look through the pics, and kind of dig the more industrial look of these.
None of these really do much for me if I’m being honest. Really great review though
Great review!!! The Deuce appears to be my jam.

Don’t take this the wrong way, because I came away feeling so much differently by the end, but they almost feel like a toy. Like it’s not a serious piece of golf equipment. They are just so light and the materials, especially in the grip, just feel like they are 90% air.
It’s really hard to explain. The Deuce though – I’ll have it in my bag regularly going forward without question.

Hmmm, that’s really interesting and the fact that you say you’ll have it in the bag makes me question it even more. For me, that lightness probably wouldn’t be good for distance control- and I realize that you’re in a similar climate as myself- have you had a chance to put it through many paces yet? Curious how that lack of weight translates to control from a distance perspective.

I’ve spent a ton of time with them, both indoors and outdoors.
First, I’m not a great distance control guy to begin with on lags. Much better closer in, though a tendency to leave putts short. I didn’t see the latter issue much at all with the Deuce. It was a little quick off the face in general, but I never felt out of control and had reasonably good success (considering my limitations) with lags.
Best speed control for me was with the Prism, but I couldn’t get that one to go where I wanted it to.
It doesn’t feel like the head is lost even with the lighter weight, which goes back to the balance point I believe.

Great feedback, thank you!
Great review! I like the Deuce and Duke. It’d be Deuce all day if it wasn’t center shafted. I’ll have to keep a lookout for places I could try one out.
These have a good look about them. If I was buying I’d probably select The Duke.
I used a Sacks Parente Series 54 for 3-4 years. This is the predecessor to the Prism. It is a great putter. Rolls the ball very well. I do think they should bring back the vernier acuity alignment system. To me, it’s the best alignment aid available today.

Nice write up [USER=1193]@Hawk[/USER]. I’m sure the technology works well but there is something about the color scheme that doesn’t appeal to me.
So is Sacks Parente gone and renamed to Newton golf now or are their putters now just Netwon golf? Or just the shafts they make with these Newton heads? Sorry for the confusion but I didn’t see it and may have missed it.

Nope lol. Finding info was a challenge.
Had a chance to play the Prism for our round Tuesday. Wasn’t sure but I really like this putter! Stays very square during the back stroke and squares very well for me through impact!
The feel is a bit different from my DF-3, but not enough to make me dislike it! The DF-3 is very soft hitting and I enjoyed this being a bit more firm!
I had 29 putts yesterday which is a bit lower than my average, so I’m happy with the results!
For me, I wish it had a way to pick up the ball. May be a little thing, but I lag well and we take gimmes!
Overall, very good putter that I’m sure many people will buy, if they give it a chance!
