I am extremely please with the Garmin Approach G6 Handheld Golf GPS. I have been using it for approximately 2 weeks now and have quickly "mastered" the key opperations, yesterday was the first time using it on an away course and proved so useful showing all distances, hazards etc., on each hole. I don't think it has yet improved my golf but has taken the guess work out of it. The facility for measuring the average distance for any club is very useful. I have found that a full battery charge lasts for 3 full 18 hole rounds.
