Do this easy Tap Test to learn if your putter has a Sweet Spot
Detrimental Impact Pads -- Some other putter makers embody pads on the impacting surface of their putters, touting it to be some kind of benefit, These pads soften ball impact and drain the transfer of energy from the putter head to the ball, That is detrimental for putting performance, but it is not the worst of it. These soft pads have have hard margins and sometimes the ball is struck by the soft pad, but all too often it is struck by the hard margin, That makes the transfer of energy from the putter to the ball unreliable -- sometimes the ball will get more launch energy, sometimes less. Nobody needs to be a physicists to understand that unreliable impact is bad for precision putting.
Detrimental Impact Grooves -- Some other putter makers embody grooves on the impacting surface of their putters touting that it in some way benefits putting performance. These grooves soften ball impact and drain the transfer of energy from the putter head to the ball, That is detrimental for putting performance, but it is not the worst of it. If there is a vertical component to the grooving, that can interact with the dimples on the golf ball to throw the ball slightly off intended line especially on very low impact short putts. Nobody needs that. .
Smooth Hard Impact Surface is Best -- A smooth hard impact surface is best because it fully transfers energy from the putter head to the ball in a reliable way, that is very beneficial for precision putting, Quantum has such an impacting surface and that makes it the Best Golf Putter.
Whould this Impact tool be capable of sweet impact - of course not!
Even though putters can be designed to have polar symmetry, most are not. Of all the putters on the market today, only the Quantum Putter is capable of sweet impact. Why? Because it has a symmetrical grip connected to a perfectly straight sturdy shaft that is perfectly vectored into the center of mass of a symmetrical compact head -- each and every requirment for sweet impact.
The physics of sweet impact is difficult to explain but easy to understand by analogy. Just imagine a tennis racquet like the one shown on the sidebar graphic. Would it be capable of sweet impact? Of course not because something as ridiculous as this tool would be incapable of sweet impact! .
It is easy to learn whether or not any putter is capable of sweet impact, Just hold the test putter lightly with one hand and then use the finger of the other hand to tap the impact spot on the test putter. If the putter twists due to this pressure, then it is incapable of sweet impact. That twist will always send the ball off intended line with adverse side-spin.
The Quantum Golf Putter has perfect impact every time; not so with other putters,
Sweet impact is easier to feel than it is to explain. Tennis players know sweet impact, but golfers don't and here is why. With one exception, golf clubs are heel shafted so they do not possess polar symmetry and always twist open upon impact -- the one exception is the Quantum Golf Putter which possesses possess polar balance, and that makes it best.
