A GPS that can navigate both in water and in land is all you will need in any type of expedition. The Garmin marine GPS is a dependable chart plotter with a built-in base map enhanced only by Garmin. It has a Course Deviation Indicator (CDI) which is a feature normally found on aircrafts but is equally useful for the marine environment. The CDI technology can tell you when your boat has veered off-course and at the same time guide you to get back on the right track.

On land, the Garmin marine GPS can help you find your way on interstates and major thoroughfares across the US and North America. This city navigator is voice prompted and gives out turn-by-turn directions. For more detailed road directions, this GPS can be pre-loaded with the automotive kit of a particular city or state you plan to visit. These automotive kits are sold separately.
