Digicue is a metric tool only.......you must do something with the information. Think of Digicue as a detection alarm......okay? So it alerts you to something but you have to go look at the data after each shot, or all the shots later on, to see what the device says happened even if the shot goes in. But when the OB goes in, why bother since misses truly count. If you ran 2 racks of 10 ball and it activated on every shot, sans break shots, or busted 3 racks playing straight pool, do you care? If you practice playing a couple racks of 9 ball and want to correlate the data to any specific shot you missed, or made, the device does not allow you to recall what you did wrong or what to do to fix it presuming anything about your stroke deserved being changed.
You don"t need a perfect golf swing to win the US Open or any golf tournament. You just need to play better than the field and the same applies to pool tournaments. Shooting at the flag can win or lose a golf tournament but aiming to get reasonably close for a makeable putt is a lot smarter. Well, Digicue doesn't tell you how or what you should do, presuming anything needed to be done, to keep it silent. That's where either video or an instructor or at least a knowledgeable partner is needed. Digicue only alerts you to something & then you have to experiment (trial &error) trying to figure out how to quiet it.
I know when I am satisfied with my stroke. I can tell when I am not hitting or penetrating the CB properly and can feel when my stroke has rythymn, balance & acceptably straight and also when it doesn't. I learn more from using my Apple phone's camera which also has a slow motion option instead of reviewing metrics well after the fact. Video allows me to evaluate and learn whereas Digicue recites data that does not help me recreate or see what I might have done wrong? That's why you need a practice partner or instructor otherwise I'll stick with using video. When you are pocketing balls and Digicue goes off, do you really care? It's only when you miss that matters to me because the one thing no one has spoken about is position play. If I don't manuver the CB in to right window, sooner or later I am going to give up the table. It means I have to use the right stroke velocity and English when needed.
Digicue does squat for position play and keep in mind you are looking at data only, not your stance, head position or movement, cue velocity, etc. It is stagmant information versus actually seeing what you did. For less skilled players, which is terminology that irks some Azers to read or hear, Digicue offers a base of information to work with and try to improve results. As someone pointed out earlier about Lee Trevino's golf swing, and let's not forget pros like Doug Sanders, Julius Boros and especiall Jum Furyk, perfect isn't needed to be a champion. They knew that consistency was the ingredient for success even with an imperfect golf swing. Being a complete player requires knowing how to improve and I submit more advanced players will find that Digicue is interesting but not really well suited for their caliber of play. They will learn a lot more from reviewing video then looking at statistics that would be more meaningful to those less skilled...IMO.
