The all-knowing Izzo SWAMI Voice Golf GPS Unit will help you see and hear your yardage. The SWAMI will hitch a ride with you on your wrist like a watch, or as a clip-on clinging to your hat, belt or glove. The SWAMI will tell you where you are on the course, and give you the exact distance to the front, back or center of the green. It is able to do this because 30,000 golf courses from around the world are preloaded into it. Features include auto-course recognition and auto-hole advance. The rechargeable battery can easily take you through two full rounds. It’s waterproof and quite durable, unless you decide to take a whack at the SWAMI with a sand iron for telling you that you’re stuck in a bunker.
