The Garmin Approach R10 is pretty versatile and works well whether you're using it inside or outside. One thing to keep in mind is that while you don't need special balls for it to work, the manufacturer does suggest using Titleist RCT balls if you want more accurate spin rate measurements.
These balls have a reflective layer that helps the R10 get more precise spin data, especially useful indoors. Our research shows that using these RCT balls can really improve the R10's performance in measuring spin rates indoors, which is important for getting accurate simulation and analysis data.
Without them, you might notice that the spin numbers aren't as spot-on, which could affect the overall data quality. Besides spin rate, the R10 does a good job with tracking things like distance and ball speed, even with regular golf balls.
This makes it reliable no matter where you're practicing—whether it's an outdoor range or an indoor setup. So, if having precise spin rate data indoors is a big deal for you, then picking up some RCT balls might be a smart move.
But for just general practice or outdoor use, the R10 should work just fine with the golf balls you already have. In short, those RCT balls boost indoor accuracy, but the R10 is still a solid choice for tracking your practice both indoors and out.
