You may download to your iPad an store as many maps as your iPad's memory will allow, so you don't need an internet connection to use the maps in the field.
The app also includes useful planning and navigation tools, including a multi-function digital compass, a search feature covering 10 million points of interest, and a ruler to measure the distance between two points.
You may also register for a free account to save trips to the Trimble Trip Cloud for storage and for syncing between devices.dist
