With a Junior Conversion Kit you can convert any Pro model into a Junior model.
This comes with a Junior model arm and stem.
The Eye Coach Pro is designed for players of any ability level. You start by hitting at ½ speed until you are consistently hitting the Eye Coach correctly. The only difference between the two models is that the Junior is for players shorter than 4’2”. This size variation allows all players to make contact with the ball just below the shoulders.
