It , in my opinion , does not cure target panic. It does, however, allow you to shoot like someone who has no TP .
In my case TP has changed as I have tried different things to overcome it.I used to not be able to come to full draw when on target.Now, I can come to full draw on target no problem, but once anchored I really can't hold and expand thru the shot with any consistency. And once in a while when I really am trying very hard I will have a really bad colapse release.
I keep working at it and one day I will beat it. But until then the clicker is my key to confident, accurate shooting.
BTW in one of the MBB dvd's,Ron LaClair says that a clicker is the only thing he knows for sure will stop target panic.
