Currently use Tag Heuer golf watch which I am less than happy with. Watch is very slow to change yardages. Unless you wait for yardage at your ball yardage will be too high. Very annoying.
Long broomstick putter. Used for number of years when anchoring was allowed, stopped when ban occured. Was a much better putter with long putter. Going to try with the no anchor rule. I think I get a better view of the selected line from above like the long putter affords.
