Review on SkyCaddie SG3 Golf GPS: Your Ultimate Guide on the Green (Black Model) by Tonya Zayas

I think the SG3 works exactly as advertised. The yard is dead for distance. It will last a round and more on a normal set of batteries. Batteries will drain quickly if you use the backlight (which is optional) or if you don't remove all stored ammo. For those who just want to know the distance to the front, middle and back of the green and want to collect points on each hole, this is the device for you. I use batteries and replace them in the device after each round. He had the SGX but returned it for a refund as it wasn't user friendly and kept disconnecting.
