Summary: SG3 has very good accuracy, display is very good and it's light and easy to handle. Big downside is the AA batteries. I go through 2 batteries every other round.
Summary: Very Accurate GPS. This will eventually improve my game once I fix my swing. The only issue I have is that it uses AA's as opposed to a rechargeable lithium.
