The field of sport is constantly shifting throughout the years and the application of technology in this arena has made a lot of influence on how it is being played today. The marine sports world has not been exempted. The invention of the Global Positioning System (GPS) has made many voyages and marine sports easy and safe.

Whereas mariners in the past had no way of determining their course on the world’s oceans except by watching the stars, today’s sailors and fishermen enjoy far safer navigating thanks to GPS technology.  The Garmin GPSMap 541s Marine Navigator is but one such device that makes use of signals sent to it from satellites orbiting the earth which allows a person to pinpoint their exact location on the world’s oceans, rivers, etc, any time they need to.

The GPS technology was initially conceived for military purposes by the US Department of Defense around 1973. Through the years and several technological advancements, the GPS navigational equipment was finally made available to athletic sports and the marine routing system. The modern GPS system is composed of twenty-four satellites orbiting the planet in such a way that four satellites are aligned to a GPS receiver anyplace on earth.

Today there are many GPS devices designed for marine use on the market and all are waterproof with a host of different features that can assist sailors to set a course no matter where they may be.  By using an integrated electronic map a sailor is able to receive information regarding his current position.  These maps are pre-programmed into the device and more can be downloaded as needed.  Anyone who enjoys being in a boat on the water should own a GPS device that will provide them with important information for any lake or river, including their position at sea any time they need it.

Some GPS receivers resembling Garmin GPSMap 541s Marine Navigator would provide detailed bottom information and enable the user to distinguish fish from other background structures. This instrument would greatly help boatmen and avid fishermen to net more fish since the marine GPS can point out places where more fish can be found. Additionally, it would also update boaters on the movement of the currents, shapes of the waterways and even help find underwater caves.

Smaller and portable GPS receivers are normally employed for recreational purposes and would contain points of reference for the latitude and longitude. These points and routes information can be stored in the unit and are termed as chart plotters, the most recent development in the present GPS technology. The nautical charts are scanned and stored as digital files and then exhibited on the LCD (Liquid Crystal Display) screen. The overlying positions are supplied by any GPS receiver similar to Garmin GPSMap 541s Marine Navigator. As soon as the positions are identified, the GPS receiver would offer the appropriate course information for the navigator, a significant leap to simplify the navigation process for professional and casual boaters.

For anyone who enjoys being out on the water a GPS unit is a very useful and necessary addition to their boat.  Users can accurately pinpoint their precise location and safely and simply plot their course from one destination to the next without any fear of miscalculating.  For fishermen the added features are a real help providing them with detailed information about where the fish are as well as giving them up to date weather forecasts so that they can enjoy their fishing experience safely.  A GPS receiver is essential for anyone who puts safety first.  Besides all the wonderful information available at your fingertips this device will also be useful should an emergency situation arise and your exact location is quickly determined, making rescue operations faster.
