Using a Bushnell Phantom. It's as accurate as I need, for F, C, B. It seldom aligns with what the course markers are placed to be, or what the scorecard says. But imo, that's on the course having 'cheater' markers.
Only bad thing about these GPS units is they do not do doglegs, always a straight line from teebox to pin. Which is great for someone like Jake, but not me.
And like a dumbass, I'm sitting here and just now remembered it will show me other things on each hole. I've only had it for a couple years, so I've got that excuse.π«
