H.L.
I would say a series of lessons with his PGA Professional. If he is a golf fiend, he might appreciate it. My husband is a PGA Professional himself and he says that there is always something to improve in himself as well as in the lessons that he gives. Good luck!! My husband is also impossible to buy for and golf stuff is OUT in my household as he can get it all at discount for himself and he has all the new stuff that he looks at everyday as well as the merchants coming directly to him.
