Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Do you want to locate your current location by GPS?
Or do you want to locate the golf course, specifically?
I would think, the former.
There isn't good support for your device from GolfBuddy, and the instructions for the WT4 are what little I can offer at present:
While in Watch Mode, press the OK button (at lower left).
Then touch the GPS Tracking icon. (Walking Man icon.)
Then press the OK button to start recording your position, and the bottom-arrow button to stop the recording.
(Perhaps what you're looking for is simply: While the time shows as if it were a digital watch, you press OK, and get a choice of several icons. One of which is a golf green - maybe that's the function you need.)
Let me know if this helps - or doesn't. I'll try to find the exact info for your model itself.
