The Talking Golf GPS
This is the golf GPS with over 30,000 global courses that audially provides the distance to the center of a green or the distance of the previous shot without the need to pull out another device. It clips inconspicuously to glasses, visors, caps, or shirts and connects via Bluetooth to most smartphones to provide the exact distance of your last shot and the distance to the center of the green at the touch of a button. App provides an interactive map that displays course hazards. Supports 35 languages. Its battery provides up to five 18-hole rounds of play before requiring a recharge using the included USB cable. Weighs less than 1/3 ounce.
