You came here with a ridiculous valuation of your company, no business plan, so on that reason I'M OUTOur group was saying the other day wouldn't it be good if you could have a small can of foam like they do for football free kicks. ?. Little spray behind your ball, when you replace your ball you sweep it away with your putter. Dragons den here I come?
Go for the green ones, not only will your playing partners not be able to see it, neither will you once you've took a look at the putt from the side or behind the hole.
Found these two on the course yesterday. One did not fare too well with its encounter with the mower.A story from a few years back
Lyme Regis had a notice on their board from the head green keeper
" Would players please stop using £1 coins as a ball marker"
With a £1 coin cut cleanly in half stuck to the notice.
The poker chip ones are daft. The marker(s) I use are all thin and flat, so if anyone does hit a wayward putt it should roll over it. I don't know why the poker ones exist. You might as well use an up-turned saucer or a coffee cup as a bloody marker.
