The Caddy Aid GPS device features overhead photographs that allow you to calculate distances to anywhere on the course. The software comes on a PDA (Personal Digital Assistant) and gives distances to the front of the green and total carry as well as lay-up distances and hazards. The Caddy Aid GPS Software can be downloaded onto any other PDA or Smartphone for £59.00. Course downloads are available for £7.50 each, or at various prices for bundle deals.
The colour photography helps to give a better understanding of courses you have not played before. If you already have a PDA you can reduce the initial cost by not needing to buy a GPS unit. The device is not quite as easy to use compared to other software, and the course downloads aren’t particularly cheap.
