"Conforms with USGA Rules"
Decision 2012-650
Although 13 clubs account for 60% of ALL golf swings, 40% of ALL shots are hit with one club. That's right, the putter!  My P&SI-EGOS is the absolute best and most expensive club in my bag; as it SHOULD BE!
Andy, I've had the P&SI-EGOS for two weeks now and there isn't much else to say but thank you!  It's been two weeks of more consistent pars, more par saves, more birdies, more back to back birdies, and more long putts made then I would normally have in two or three seasons combined. That all equates to more fun on the golf course!  I also now know the frustration of lipping out putts and burning the edges of the cup consistently when I don't get my speed right. It's funny to think I could go from a pretty mediocre lag putter to a player who now expects to make putts without spending time practicing putting, but just using the P&SI-EGOS to properly read greens and putt while playing a round of golf.  If you ever invent something that would help chipping please let me know.

Andrew, just giving my take on it.  The P&SI-EGOS putter has no bias. It accommodates any putting stroke whether you have an “out-to-in” stroke or straight back & straight through, or open to close; the putter adjusts to your putting style because of the 360° balance. It works for any feel regardless of preferences for face-balance or toe-hang.  Heck of a good putter….

Patrick gives away Texas Open. Sees exact break with P&SI-EGOS. 
Here's the Solution:
The P&SI-EGOS putter which comes with a Patented & Proven   Operating System called EGOS.
EGOS - Expert Greenreading Operating System
Confidence Levels will skyrocket knowing exact lines for your “preferred” speed to hole putts. Only a practiced “calibrated-for-that-day” stroke needs to be REPEATED before getting the ball out of the hole!

For the win, Rose missed this 72nd hole putt to the right. Ditto Garcia. Both putts holed with P&SI-EGOS. 
Key talking points from EGOS video: 
Notice with EGOS there’s no need for maps, no stemp, no foot-feeling, no staring from all sides, no looking for drainage routes, no crouching, no pacing off, and most importantly, NO WASTING time! The EGOS takes snap-pic “angel/gap” reads that automatically correlate to a precise “direction & amount” of break. EGOS is incredibly accurate even on SLIGHT breaking putts.

From PRACTICE GREEN calibration, combined with previous putts taken during the round, the line is known for the speed-you-like-to-hole-putts, all accounting for the course conditions at that moment. Yes Sir, that’s Expert Greenreading.  

Remember Expert Greenreading with EGOS is based on GRAVITY, which is to say they both always work. When there’s a bad greenread, it’s pilot error. Correcting pilot error may take a lesson or two, which is free for P&SI-EGOS owners. Then, when there’s NO doubt about your greenread, all focus is on the putting stroke as it should be. If everyone used the P&SI-EGOS, there would be no more dallying around reading greens and more putts will get made. 

Each P&SI-EGOS has it's own engraved PIN# to access "EGOS Owners" for video lessons & troubleshooting; plus Math proof.
Please consider 400+ years ago a putter was created to get the ball into the hole. Due to optical illusions on greens, the line is misread like in clip above, so it takes 2 or more strokes before getting the ball out of the hole. Verified by Owners, the P&SI-EGOS will eliminate ALL optical illusions, so can’t help but make more putts! Plus it’s Guaranteed, Quick, Supported and USGA conforming. So why have any other putter in the bag?  More details at Why $800+. Offering at ebay; search with “P&SI-EGOS

(Every week there are clips of misreads to post, but Henrik is just so demonstrably shocked that it's a stellar example, so it leads.)
I love this putter! I'll never have a need to purchase another putter. Everybody needs this putter as this would speed up play and make playing more enjoyable because using the EGOS builds confidence and you make more putts. Every golfer pro and amateur should get the benefits by making this their last putter purchase.

This is NOT Plumbobbing!

  • Plumbobbing has no math to back it up. Plumbobbing has no guarantees. Most that do it, can't explain what the heck they are doing.  Plumbobbing cannot read greens correctly EVERY single time and the Owners page shows why.

  • Using the P&SI-EGOS is called "Expert Greenreading" which guarantees an accurate, precise greenread EVERY single putt; and there's Math to prove it in the EGOS Owners page.
Henrik never sees right break at the hole. Stenson sees it with the P&SI-EGOS. 
Phil has the 1st EVER 62 in a Major if sees the wicked right at hole.
62 happens with EGOS:
