How the Navionics GPS Chips work

There is no surprise to find a seasoned sailor living in his or her boat for a majority of the days in a year. As a sailor you have to rely on chartplotters to find your way because there are no sign posts or traffic lights in the sea. Many modern boats come with these devices, but you can still add your favorite one. A fishfinder integrates GPS information with the electronic navigation chart to allow sailors to see the direction they are going and their exact position at sea.

A sailor has to rely on a company that provides reliable charts/maps for using while at sea. There are companies that specialize in monitoring and mapping the sea so that they can provide the data to sailors through the use of integrated global positioning satellite (GPS) technologies. The whole system works as one, which usually includes an internal GPS.

How does a GPS chip fit the whole picture?

For specific fishing and sailing areas, there are companies best placed to offer maps because they have the experience and expertise to do so like Navionics.  At this point a GPS chip comes in handy, in addition to the GPS/fishfinder.  In addition to giving you current positions relative to the overall sea map, the right chip will also let you do conventional computing with the GPS capabilities to show you the potential location of fish. You can take a photo of your big fish catch, and then geo tag it so that others who view it will know where it was taken from. With that, you can also share it to your social network profile like Facebook and Twitter for friends and followers. The following section will explain the navionics gps chips.

The Navionics GPS chip

ContoursThe fishfinder device used on a boat will have preloaded charts that you use for navigation, together with the GPS chip onboard. It’s the chip that determines what maps you are able to use, and how accurate and clear the maps are. For you to use Navionics charts, you will have to use a Navionics GPS chip. It’s the chip that allows your chartplotter device to communicate with the maps service online on a real time basis. When entering a zone that is only mapped by navionics, you will have to change to Navionics GPS chips, so its always handy to have the chip even if you are not using it fulltime.

The good news is that many modern fishfinders like Raymarine and Furono all support the easy swapping of chips. A good GPS chip will be fast such that when changes from one screen to another on the fishfinder take place immediately. This is a very sensitive property because the boat can be moving at a very high speed and if the fishfinder/sonar takes time to re-write the chart, then you can get lost.

Benefit of the GPS Chip

Instead of having to download and install maps every time you change regions, a Navionics GPS chip lets you tap into the detailed company maps by simply popping in the chip to your fish-finder unit. The GPS chips come with different map details. The simples ones are ideal for just sailing but a fishing enthusiast will need the one that can also locate various utilities such as a port, and the contours, which then tell you whether your boat will fit in some lakes or rivers.  The Platinum line by Navionics is a fishermans dream and gives precise detail in both 2D and 3D modes.
