I have the Caddy Lite, which is now available from Golf Plus for £99.00. It does exactly and only what it is supposed to do: it tells you how far you are from the green(front, back and middle) and from various hazards on the way (providing they have been mapped), and it automatically knows when you have advanced to the next tee. There are no fancy icons, legends, graphics or colour - just the numbers. It doesn't tell you which iron to play or keep a record of your scores or do any post-round analysis. The assumption made by the manufacturers is that you just want to get on with your game and have no interest in fiddling around with messy buttons inputting scores or accessing features available on cascading sub-menus. If you are a reasonable golfer, the confidence you get from knowing exactly how far you are from the middle of the green and hence what club to choose may save you a couple of shots a round. Golfers, as you will probably agree when you read this, can be suckers for the latest gizmos - ball finders, swing trainers, range finders, electronic scorecards etc. - and they are nearly all rubbish, used once before consignment to the garage and then the dump. The Caddly Lite is different - genuinely useful and unobtrusive - and I shall always keep it on my bag.
