This is a like new IZZO Golf Launch Master Launch Monitor. I received this as a gift, but I don't need it since I have a Garmin R10 launch monitor that I use almost daily. I used it twice just out of curiosity and compared it to the Garmin, swing-for-swing and found that, while it lacks many of the datapoints the Garmin provides, this launch monitor is pretty in-line with the Garmin with well struck shots for the data it can provide. This unit will give you fairly ridiculous results for very poorly hit shots though, especially if you severely top the ball, since it doesn't actually track the ball itself. This goes for about 300 bones on another site and this one is essentially new, even includes the little paper measuring tape and batteries.
