Doesn't sound that encouraging....
RANGE BALLS OR REAL BALLS?
Another hard truth; if you’re planning on collecting data while banging limited flight, beat to hell, or otherwise nondescript range balls, you’re not only wasting your time, you’re wasting money. If getting data with the ball you play is impossible, you should at least try and get data from a ball that’s similar to the ball you play. Failing that, make sure you’re using the same ball. That shouldn’t be too hard in indoor environments or hitting nets, but understand that if one ball you’re hitting isn’t like the next, there’s not much to be learned from whatever numbers appear on the screen from shot to shot.
If a literal mixed bag of range balls is your typical use-case, and you’re looking for more than just a good time, it probably makes sense to save your money.
EXPERT TIP - IF YOU'RE ON A BUDGET AND SERIOUS ABOUT DATA, WAIT
We understand how enticing a $500 launch monitor might be. There's plenty of demand, which is why there are a growing number of offerings trying to satisfy the cravings of average golfers. We've provided our best bets for those who absolutely want to buy now, but in our opinion, the offerings in this category are immature and lack the fundamental horsepower necessary to deliver data accurately and consistently.
If $500 is your ceiling, our advice is to wait until the technology improves, or until you've saved enough to step up a class. If the money is burning a hole in your pocket, spend it on lessons. There's more value to be had there than on a device that will almost certainly provide mixed and often unpredictable results.
