Review on Improve Your Golf Game With PlayBetter Swing Caddie SC300I Launch Monitor - Choose From Accessories Bundles For Accurate Distance, Smash Factor And Ball Speed Readings by Tim Duncan

Easy to set up, positioned correctly - worked from the first swing. (works without phone connection)Would miss one or two shots in a series of swings, maybe operator error (placement or aiming direction).Most accurate with short irons, a bit off with Driver (shorter distance than actual, about 10% off, tested with Bushnell laser range finder)Voice is very handy, however, it distracts other golfers at driving range. Would be nice if blue-tooth function would connect to blue-tooth ear buds.Phone connection app is useful for recording practice sessions, and/or for 2nd person to assist with shot feedback.I believe that the SC300I is well worth the price and better than most comparatively priced swing analyzers.
