An absolute must!
I used the trainer on our High School Golf Team recently because of our lag putting problems specifically. My observation was erratic distances caused by inconsistencies in roll quality off the face. By using the trainer with our 5 Varsity players, I was quickly able to make adjustments to either their ball position or handle lean to create consistent rolls off the face. Within 30 min, for all 5, their 40’ proximity was reduced from 4’-5’ to 2’-3’. We now check our roll quality before each tournament to make any quick adjustments necessary.
