Each ball reportedly has a 40-hour battery, making them perfect for multiple after-hours rounds. The only trick finding a golf course that will allow you to play at night. (Stupid rules.)
But therein lies an opportunity many golf courses may consider. If their patrons complain about finding a tee time on a busy Sunday, or if the course is prone to overcrowding, extending tee times past dusk may be the answer.
Oh, and if you’re wondering whether or not night golf is any fun, here’s a video I took of Graeme McDowell defeating me in a closest-to-the-pin contest in Chicago from 2012*. It’s a little hard to follow the golf ball tracer, but the guy stuck it to three feet.
(*Note: All that’s required to have a similar experience is the 2010 U.S. Open Champion and gallons of Guinness Black Lager.)
