Thanks for standing bye as I took a 3-day vacation from the blog with my birthday this past Friday. To get back into the swing of things, we need to take a look at the latest Brian Manzella video, the Essential D-Plane video. I believe this video is a mandatory to watch if you're serious about improving your golf swing.
This video has been discussed over at my forum (http://richie3jack.proboards.com) quite a bit and one of the posters still didn't understand why Trackman was such a great tool and why not just examine the biomechanical aspects of the swing.
I would make the analogy that Trackman is much like a forensics lab. Let's say I'm a detective and I come across some skeletal remains and from my experience I make an educated guess that they are the remains of a male teenager. I could then start searching for missing male teenagers in the area. But instead a detective will take it to the forensics lab, and they may accurately determine that the remains are from a female. Along with determining the approximate age, ethnicity, size, how they were killed, etc. I could then use that *accurate* knowlledge and know where to look and then get back into doing the good, old fashioned detective work to solve the crime.
SliceFixer (aka Geoff Jones) mentioned this in an interview with Ralph Perez at the Gotham Golf Blog. He said he had an issue with hitting a low, diving hook and thought he had a problem with his club path. But when he measured his swing on Trackman, he found that his path was fine, but his clubface was too closed at impact. Had he not used Trackman, he may have been doing 'good ole fashion detective work' on curing his path woes which were not there instead of finding a way to cure his closed clubface.
