Very true. But bushhells are the smallest, handiest, cheapest, most likely to be used. They're also the devices most likely to cause slow play.
So sure, other devices (GPS related) do exist, and may proliferate. BUT aye, here's the rub: if they are good enough, they will not slow play at all. There's nothing wrong with allowing their use. One can already do so in casual play, and if local or club events want to allow them, then more power to them.
It just remains very difficult to distinguish between them and bushnells for purposes of rule making.
Therefore it seems to me to make the most sense to make the local rule apply to ALL devices. Sure this throws out a little baby with the bathwater, but there's no better way to do it.
And the bottom line remains that all it takes is for any course, or tournament committee, to invoke the local rule if they wish. As I say, at the many courses with GPS-equipped carts who host competitions, it just makes sense to allow such to be left on. Too many odditities have happened already at such courses. And that's just one small example.
It's also just good policy NOT to allow them at the highest levels. They don't need the help, and it's also not a good example to set.
No?
