In the past, mariners use to navigate by the stars. Today, they navigate by satellites through the Global Positioning System (GPS). This brilliant piece of technology can locate a person with a GPS receiver anywhere on Earth and report back their exact location with astonishing accuracy. It can also tell a sailor out on the ocean or lake how to get to any chosen destination quickly and easily.

Hundreds of different types of marine GPS units are for sale. As you can imagine, all are waterproof and have various features that help you navigate out on the water. The units have pre-programmable databases for all the rivers and lakes as well as nautical markers for lights, buoys, sound signals and day beacons among other things.

Not only will a Marine GPS unit aid a fisherman or boatman to keep his bearing, it can also help them catch more fish. Using the GPS navigation maps the device can indicate what the currents are like and where the best places to find fish. It can even locate caves and contours in the waterways.


The smaller marine GPS units are typically used for recreational use and are usually portable as well. The gadgets contain bearings for longitudes and latitudes that assist one to establish sunset and sunrise. You can also save the routes and tracking points.
