Samsung has unveiled a new version of the Galaxy Watch 4. The new model offers practically the same specifications as the regular Galaxy Watch 4, but with a few software adjustments aimed at golf fans.

Do NOT waste your time, energy, or money on the smart caddie version of this watch. I have the Smart Caddie Active 2 and it has never worked well, if at all. When it does work the yardage is never correct and it takes way too long to get the updated yardage. Save your money and get a golf app for your phone.
