This device helps you line up with your target and with your swing path at impact. A wider setting for driver, full swing, irons, chipping and pitching plus putting alignment. Portable enough to take to the range. One complaint is that not all the holes were an exact diameter, i.e, there is one hole that is always so tight that the stick could not be inserted through, but all the other holes were loose enough for the sticks to glide through. If there was something I would like to see is clamps to attach at least 3, at most 5 alignment sticks to the backside of the tour aim. I think this would be a great addition either attached directly or as an add on to attach later.
