Secret Santa for a golf fanatic

[Urban Sports]

Evening,

I got my brother in law for secret santa, the criteria is around £100, he's mad on golf, I know nothing about the sport really so could do with a bit of help, I was thinking something like this

Is it any good or can anybody recommend anything else, obviously it's something that he wouldn't normally treat himself to, he's 26 if that makes any difference?

Cheers
