The Swami 6000 by IZZO features a vibrant 2" color screen and is preloaded with 38,000 golf courses worldwide. Get your distances to the front, back, and center of each green and even see how far it is to hazards and doglegs. When you start it up the Swami 6000 has auto course recognition, so it knows where you are. And don't worry about having to toggle through anything during your round. Auto advance moves with your from hole to hole. You can also keep score, track greens in regulation, putts, and see how far you hit your last drive. Strong, internal magnets allow you to stick the unit anywhere there's metal; like a clubhead or the frame of the cart. The included rechargeable lithium battery gives you about 16 hours of power.
