Flightscope, trackman and other similar units are pretty much out of reach for most of us. However, I was listening to the Sirius/XM PGA John Maginnes program on the way home from work Monday, and he was interviewing the inventor of the ES12. It is a doppler device that gives you audible distances of your shots. I went to the web site, http://www.ernestsports.com/ , and it seems good. The best part is that it sells for $249 with a special discount if you put Sirius/XM in the product code section that makes the price $199 until this Friday. JB, this might be something that THP might be interested in testing.
