Golf courses are a great place to detect! However if I were you I would do it at night if possible. You don't want other ppl seeing you and thinking its okay for them to do it too. Keep it to yourself and be discreet. Make sure you don't dig on the greens or even the tee boxes. Rough areas, fairways near roughs. I would try to do beside the tee boxes as that's where ppl are getting things from their bags or coming off of a green to put things back into their bags. Great place for coins, rings, ball markers etc... Have fun
