While a set of clubs and balls is all you need to start a round of golf, some must-have golf accessories can make your time on the course comfortable. You surely don't want to carry all your clubs in your hand, so the first essential thing you will need is a Golf Kit or a bag. Having sunglasses, Towels, Umbrellas, Jackets, and other necessary gadgets is required to protect you from hot weather, rain and other weather changes. Rangefinders and GPS devices will help you improve your game. So, while you can skip a few of them, carrying at least the essential tools is important.
