Navigating on the open water away from land has always been challenging and very exciting. Boating can be a very rewarding experience if your boat is equipped with the proper tools to ensure your safety. Good quality marine navigation electronic equipment on board aids easier, faster and safer navigation.

It is recommended to make sure that, the boat is equipped with certain marine electronics. The minimum requirement for safety is to have a VHF Marine Radio and a compass before leaving the shore. Other desirable electronics include a GPS plotter, fish finder or depth sounder,radar, and auto pilot. Other more sophisticated but nice to have items include an Automatic Identification System and a networked navigation system

Marine navigation electronics equipment operation and uses are discussed below:

Auto Pilot: It is a highly recommended tool for mariners set to go on a long voyage. Auto Pilot helps to steer the boat automatically and thus, relieves the person at the helm from fatigue. Auto Pilot is of great help for those that troll while fishing as it controls the boat direction automatically, relieving the captain to join the fishing. This tool is of great use, as it helps to save fuel by keeping the boat on a steady heading.

Fish finder: Those who fish for pleasure or hire enjoy the help provided by a good fish finder. The fish finder operates using SONAR. generally, the sonar operates by sending a signal down trough the water column until it meets an object with mass, sufficent to return a signal to the device, thus drawing an image on the screen. Thereby, showing the depth of the fish in relation to bottom structure. If a fish finder is not desired then a depth sounder with a digital readout is a good option, being less expensive.

Automatic Identification System: It is considered an important electronic tool for marine navigation. It provides other boats with your vital information as well as their information to you: the exact location of the vessel, longitude and latitude, Time stamp, Rate of turn, Course over ground etc. While the vessel is under way, the AIS shows the above information every 2 to 10 seconds, and when the vessel is anchored, the data is presented approximately every 3 minutes. Apart from providing the above-mentioned information, it also provides information about other boats or ships concerning their dimension, location, and type of the boat or ship. It is the ultimate electronic tool for collision avoidance at sea.

EPIRB: The Emergency Position Indicating Radio Beacon (EPIRB) also known as distress radio beacon is a transmitter, which helps rescue services to locate boats in distress. The transmissions are repeatedly transmitted from satellites worldwide to the various rescue services. Watercraft operators wishing to have an EPIRB must use a digital 406MHz unit. The International Copas-Sarsat Satellite System stopped monitoring for all but 406MHz signals for distress alert and location data for rescue operation throughout the world..

GPS Plotter: The GPS system now takes over the duty of the old Loran navigation system. GPS signals are broadcast from those satellites worldwide, that are a property of the US government. The GPS can be presented in digital or map format. The preferred method is on a plotter that is loaded with digital maps of the area you are boating in. Most new VHF radios now have the capability to broadcast your location with a distress signal if connected to a GPS
