Golfwith Smart Marker
The Golfwith Smart marker is a poker chip style ball marker that connects with your phone via bluetooth. Using the Golfwith and its accompanying app, a player can click just once to hear the distance to the green from the smartphone. To start the tracking function, press and hold for one second.
The Golfwith GPS app, which is free with purchase of the Golfwith, tells distances to front/center/back, gives a layout view of fairways and greens, has automatic hole recognition, and will track your shot history.
