A green reading system based around a putter/surveying instrument. The putter is solid as is the green reading system. Worth a look for those who need to improve their reads.
Is it a putter with a built-in green reading system, or a green reading system that includes a putter? Either way, the P&SI-EGOS is one of the most unique offerings in golf. Developed by Andrew Walters, a professional engineer, this system has two parts: EGOS (Expert Greenreading Operating System) and P&SI (Putter & Surveying Instrument).
Why should you be interested? What does this system offer? P&SI-EGOS GUARANTEES an expert green read on every putt. I think that’s a claim worth investigating.
P&SI – The Putter
The putter itself is an Anser-style blade with a dark finish and very minimalist engravings. The putter sports a sight line on its beefy topline, but is otherwise free of distractions at address. Where it gets unusual is at the neck. In appearance it’s similar to a gooseneck, attaching near the heel but with the plane of the shaft crossing nearer the middle of the putter. The neck is set back from the face giving it the appearance of onset, but when the putter is soled, the shaft leans forward making it play like a putter without onset or offset.
In terms of sound and feel, the putter is quite good, if a touch on the firm side.
Now, why is this a “Putter & Surveying Instrument”? Because the putter hangs perfectly vertical regardless of where the toe is pointing. This is what EGOS is built around.
EGOS – The Green Reading System
Out of respect for Mr. Walters, who only fully shares the EGOS system with owners of the P&SI, I won’t explain every detail of the system, but I will give you a general idea of how it works.
If you watch someone use EGOS, you’d probably say, “They’re plumb bobbing.” It isn’t that, but it looks like it. Basically, you use the P&SI to create a vertical reference point and use that to read the putt. The full system is explained in several short video clips on the P&SI website, which you can access only after you purchase the putter.
Having used EGOS a bit, I can tell you that it makes sense and does provide a lot of help in making reads. It eliminates visual illusions and allows you to know the direction of the break. Knowing the severity of the break and the speed requires work on the putting green before your round.
EGOS vs. AimPoint
Though it is still relatively rare to find a golfer using AimPoint, the concept is well known due to its use on golf broadcasts. Here’s a quick comparison of the two green reading systems:
Requires golfer to use the P&SI putter
Requires pre-round “calibration”
Requires golfer to use a chart
Golfer must know the speed of the green
Golfer must learn to feel the amount of slope with their feet
What I Like About P&SI-EGOS
I like that you won’t ever get fooled by the direction of the break. This alone could be worth the purchase for some golfers.
I think the lack of a chart will be really appealing to golfers who are turned off by AimPoint. Similarly, you don’t need to learn to feel the slope, you just need to look at the “gap.”
Finally, I think the putter is a quality product. It’s not the flashiest putter, but it’s clearly well made.
My Reservations About P&SI-EGOS
My biggest reservation about P&SI-EGOS is the requirement that you use the P&SI putter. I’m a big believer in getting equipment that fits your swing/stroke, and the P&SI won’t fit every golfer. Mr. Walters and I went back and forth on this quite a bit. His assertion is that the read trumps fit, and golfers will learn to like what works. He also suggested that if a golfer can’t learn to putt with the P&SI, he could carry two putters: the P&SI to read with and another putter to actually putt with.
My other concern is the need for pre-round calibration. If you want EGOS to provide precise reads on every putt, you will need to find a wide variety of putts on the practice green. While I think this is a good idea, I also know it’s an unrealistic expectation for the average golfer. In fairness, the average golfer isn’t going to find out the green speed to use AimPoint either. Ultimately, neither system is really for the “average” golfer, in my opinion.
Lastly, the price of the P&SI, $349, will be prohibitive for some. Understanding the economics of small-scale putter making, I don’t object to the price, but I do know that some will balk at the system because of it.
Ultimately, I think P&SI-EGOS is a really interesting product that can help a lot of golfers. Anyone who takes their scoring seriously knows that better putting is one of the fastest ways to shave strokes, and getting better reads is the fastest way to better putting. P&SI-EGOS guarantees accurate reads…what would that be worth to your golf game?
