I know many golfers use GPS nowdays but I feel it is just a very expensive gimmick and does not help improve your game at all and in fact is proberly detrimental to your game .The whole idea of golf is to works out the distance of each club before you hit the course,then read the distance off the hole on your scorecard and use the appropriate club.If you use a driver deduct that off the distance of the hole and use the relevent club to reach the green.Now if you dont hit a club the distance you know you can you work out from eye and course markers what distance you have left and chose an appropriatte club.Golfs about feel for distance and using the right tools(clubs) to cover the distance.Why would you need GPS to tell you a distance thats left to the hole when you may not cover it with the known distance of your irons? in which turn you have to manufacture a shot,so then theres no need for GPS
.I worked briefly in golf retail and selling £300+ GPS gadgets was quite frankly a big laugh between the sales assistants...theres Too many gimmicks nowdays that are making big cash for golf product companys,GPS waste of time and money just get out there and like Mr Hogan said feel the game.
