The Bushnell Phantom 2 slope is the first GPS device I have ever purchased. I have used apps before but this is a game changer. Although the display is basic the amount of info and data you get is amazing. I have now played 4 rounds with the device and have definitely benefited. For example even if I don’t hit the green I have been nearer pin high and not leaving so many shots short. The green pin function, hazard data and slope compensation are excellent as well. I would highly recommend to anyone wanting an excellent aid on the course without spending silly money. The Bushnell app that you get free is also as good- if not better-than others available. Delivery and service from Golf shop online was faultless as well. Thanks
