Summary: Have only used it on my home course for 3 rounds but found it to be very helpful especially when in the rough or playing the hole from another fairway. Yardages seem to be very accurate. I see no issue with battery life. I have used 2500 nimh batteries as one of the recommended options and have gotten 3 rounds before having to recharge.
Summary: I have used a Sky Caddie 2.5 for 4 years and had been thinking about a Garmin for several months (no yearly fees!) After "test driving" a friend's Garmin Approach 5 I was hooked. I chose the G3 after much debate and ... I LOVE it! I play 5-7 rounds a week from May to Sept in MO and even in the bright sun the screen is clear and easy to see.
Summary: The G3 does everything I need and is very easy to use. The "Measure Shot" feature helps find wayward tee shots as I know at what distance to look for the ball! No more guessing, distance to pin at a glance, all the info you need to pick the right club. Ordered on a Saturday, regular shipping, arrived Monday morning!!
Summary: i'm very pleased with my purchase. many nice features as an aid to playing. the backlighting is very good, but you need to have it in sunlight to read easily. quality is better than i thought it might be.
