Perks
It is easy to carry, as it weighs under 6 oz and fits right in your palm. The Intelligreen feature lets you read the depth of the green from every angle, and therefore more accurately execute your shot. Since it measures the distance to the hole from any part of the course, and has mapping for the center, front and back of the green, it can improve your score dramatically.
Sacrifices
Since the unit is not fully water proof you risk damaging it if it is dropped in the water. There is also no color display. The price is not much lower than similar models and even a few with color screens and some more advanced features. You are required to buy a subscription which runs between $30 and $60 a year to use the SG3 as well.
Bottom Line
If you want a simple to use golfing GPS that requires little set up time and works right out of the box then this is the unit for you. It is very easy to navigate the unit, plus it offers the most important measuring features for weekend golfers.
