I wasn't aware of that, I just assumed it measured both.Don said:It "estemates" swing speed from the ball speed.
FYI, if you page down on this link, it will show the protector for Ball Speed measurement. I'll likely pick one of them up in time.
Can't wait to get the thing. My main reasoning is to tone down my swing to about 85~90% on my driver to gain better control. I will likely see the same results when I did so years ago on my irons. I better controlled my swing, and it actually lead to an increase in swing speed by shortening and better controlling my swing. Right now I seem to have more of an issue of slowing it down, I don't get proper release and my otherwise straight shot or Draw turns into something between a fade and a slice. Making my faster swing a more consistent shot with an occasional Duck Hook. When I get into a rythem with a slow swing, I likely loose only 10 yards but hit alot more fairways.
