5 navigation tools
What: Depending on the hand-held GPS model, topo maps are either included or added afterwards (for a price) and they show your location.
Pros: The maps are integrated with the GPS device, so you can plan routes ahead of time or export waypoints for other users. (The Magellan eXplorist 610 Canada includes Canadian topos.)
Cons: They are small and battery dependent.
