you put your swing on the v1 software and compare it with other golfers, try and download v1 its has a free software download and you will see how it works, but in leadbetter it shows you whats right and wrong from a player swinging and shows you line of the swing, where your arms are legs etc, and you can have two swings next to each other to see if your doing right or wrong. you can then look at things like your ball flite and and he shows you how to stop a push, pull, slice. hook and asked you a lot of things and you say yes or no and he then give you drills to help, he does try and get you to hit a draw and if thats what you want then this will really help.
if you do get it let me know what you think. i think its something you can keep going back to to help with your swing. if you want to know more just ask.
hope this helps
