Launch Monitor Collapsible Alignment Stick

After a few times of setting up the SC 4 for proper alignment, it got easier and faster to do. It's very accurate, with only two mis-reads in 10 sessions since purchasing it. I also like that my refurbished unit from the company (good as new!) saved me a $100. My PRGR monitor (stolen recently) was not nearly as accurate, with several misreads occurring during each session. While my SC4 can't accurately measure club head speed indoors without using balls, as my PRGR could, the increased accuracy and the confidence that gives me makes up for it. Definitely recommended!

works fine

Easy to use. Provides valuable information. It makes practice fun.
