The original Wingman solved the cart-speaker problem by reading your yardages aloud through a remote in your pocket, and the whole line has been iterating toward the obvious conclusion ever since: sometimes you want to look at the number. The HD is that version. A 3.5-inch touchscreen shows front, centre and back plus hazard distances, so you get the glance-and-go of a handheld GPS from the speaker already magnetically stuck to the cart frame — one fewer device, one fewer thing to charge. The audio is the reason people buy the range in the first place: 360-degree sound loud enough to carry across a fourball without being the group everyone else resents, and Concert Links pairing so two units play in sync if your playing partner has one too. It's waterproof, as anything living on a cart should be. Worth it over the cheaper Wingman 2 if you'd otherwise carry a separate GPS; if you already wear a watch, the saving is the smarter buy.
