Multiple data dictionaries can be loaded into the Geo3. Digital compass is built in. Offset capability is built in. However, the offsets are all manually entered. There is a real time map display.
Logged features appear on a map as they are collected.
There is a Repeat, Pause and Resume key for easier use. You can log 10 minimum positions at one second intervals for a fire hydrant and 30 minimum positions at 5 second intervals for gas valves. This is a vast improvement over the old setting restrictions that dictated the same interval for all lines and areas, and a different one for point features. There is an icon in the left margin of the display that denotes a feature as a point, line or area. You don't have to remember that you called a small maintenance building a point feature, rather than an area feature.
