I think this would be a big seller for WGT.
You purchase this the same way you purchase Putter Pal or Shot Pal. Per shot.
You select which club in your bag, excluding the putter, you want the meter speed to be. Once selected the meter remains that clubs speed for all clubs in your bag.
As equipped my clubs have 4 different meter speeds:
R1 Driver
R11 Irons
3W and Clev Wedges are the same, I believe.
TM Wedge
I don't use Putter Pal or Shot Pal. I use avatar movements. But I guarantee you I would purchase Meter Match shots by the gross.
