Physical Device: As far as the on-shaft devices, Swing Smart is the best.
It attaches under the shaft, so it’s barely noticeable at address, it’s tiny and lightweight, and it doesn’t twist.
The only real negative about it applies to all of the on-club devices: you need to move the device (or at least the sensor) when you change clubs.
Ultimately, it was decided that declaring a "winner" was important, so we did, but just like with our Most Wanted Driver Test or Most Wanted Mallet Test, it is not necessarily true that the winner will be the best device for you.
I strongly encourage you to take a careful look at the all the information and ask yourself what you're looking for in a swing trainer before making your purchase.
All of the devices were tested by up to five different My Golf Spy writers.
In addition to this field testing, I tested each device against Flight Scope to judge the accuracy of the data that was produced. The first gives some broad information about features, price, and compatibility.
The second gives you letter grades in each of four categories, plus an overall score.
Below, you will see full explanations of each grade for each device.One area that I intentionally ignored was Price/Value.Price may be a determining factor for some people, but I came to the conclusion that it was best to judge each device purely on what it does and let the individual consumer decide what was the best bang for their buck.By: Matt Saternus Last year I said that the Swing Trainer Shootout was The #1 Most Requested Review, even more than Rocketballz, and that may have been a stretch.This year, it is not a stretch to say that the Swing Trainer Buyer's Guide is the single most in-demand review that My Golf Spy has done.Since the PGA Show in January, not a week has gone by that I haven’t gotten a comment, email, forum post, or tweet asking when it would be done. 3Bays GSA PUTT - Ultra Light & Ultra Small Something that I came to appreciate only as I spent more and more time with these devices is that comparing them is not apples to apples.
