Hi Dave
I am a pro in Oz and i use the dual track and highly recommend it. I use it in my lessons with students and find it gives instant feedback. The one great thing is that you can do full swings and use it for chipping as well. I can send you a video of me on the Dual track showing what happens during the swing with it if you like. addampga@bigpond.net.au
send me a email if you need any extra info.
Do you use one now,
I love to with mine do a one/two pre swing where I set up to the ball with the dual track, take the club back to the top of the dual track and then back to the ball and i do this again. Both times I take the club to the top of the dual track without setting it off and then on the third time i do a full swing and hit the ball.
Give it a try it is like three time the use in one swing.
Good luck
Regards
Addam
