My Dad is a huge golf nut. He’s terrible at golf, but will buy basically every gadget under the sun if it has a chance of improving his game. Garmin’s Approach S2 watches may, however, go part of the way there with a library of over 30 thousand course layouts from around the world without the need for a data connection. It uses GPS to measure the distance to the green from where you’re standing and also comes with a digital scorecard that might stop my Dad from cheating with the pencil. $US250
