Ok, here's one for ya........
Got my PBS today and took it to the range. Didn't hit full shots but hit a lot of chips and pitches (long and short). The PBS helped me realize a already do a decent job with the #3pp. However, keeping it there while pitching, I did notice really nice accuracy.
Here is the kicker....my 4 year old was with me. He is a really talented 4 year old. I have a battle with him keeping a proper grip. He grips with the left hand fine but has a really strong right hand....and uses a base ball grip.
So he sees the PBS under my finger and has to know what it's for. So, with minimal explanation, I get him set up with it on his long iron. This iron...he does not hit very high at all....and, the PBS is kind of big for his fingers but...I made it work. First ball hit, he messes it up. Second ball hit, he hits it high and long. We were about 65 yards off a practice green and he lands it on the green with a fly. He continues to do this, shot after shot. So, I take the PBS off and tell him to keep feeling like he's pressing with his trigger finger and he keeps hitting these great shots.
The grin on his face was well worth the $ paid for the PBS. I wore a blister in the PP3 area today. I can see keeping this in the bag and just making it a habit to pull it out for practice sessions.
