Gobal Positioning Systems (GPS)

A GPS is a positioning device that is a mini computer for road and water travel that can be used in the wilderness. It eliminates the need of using a map and a compass.

The GPS device will give your location per latitude and longitude with fair accuracy. The device uses signals from a number of orbiting satellites, usually a minimum of three satellites is required.

Our GPS device is an older version, hand- held, battery powered, Garmin, Model GPS12. It gives the satelitte status, our position in latitude and longitude, a compass navigation and map to our point of destination. We use our GPS for mapping and locating the boundary of our property.

Before leaving on your trip, plug into the GPS memory the location of your cabin, car or motel. Then proceed to travel, hike or boat ride. When you want to return to your point of origin, enter the cabin, car or motel from the GPS memory and the GPS will guide you back to that beginning location.

Of course, it is a good idea to have a good map and a compass with to see the overall picture of the trip.
