Golf GPS & Range Finders
GPS range finders work in the same way as sat navs in cars. The GPS systems such as Caddylite, Golf LogixGargin and Sky Caddies allow you to plan your game in more detail. You are able to download golf courses to your range finder which is the same as having a yardage chart in your hand, but instead of a book you have an electronic gadget. They are R&A and USGA approved which make them competition legal and make your round more enjoyable as it tells you where all the hazards lie.
Another type of range finder is the Laser this uses an invisible laser beam which bounces off a distanced target at a click of a button, using advanced digital electronics; the range finder instantly calculates the distance within +/- 1 yard /metre. It then shows the range in either yards or metres on a through-the-lens LCD display. When using this gadget it literally takes seconds for the laser to relay the measurement, this is the most accurate form of measurement out of the two types of range finders. These are also R&A and USGA approved and can also be used in competition play.
