GPS chartplotters are exceptionally useful maritime navigational tools. They are the latest innovation in course plotting and one of the most practical uses of GPS technology. Whether it's a large cargo vessel or a small fishing boat, a GPS chartplotter can create route plans and provide accurate information on where you are and what path the vessel has taken.
GPS Chartplotters – So Where Do You Want to Go?
A GPS chartplotter is usually placed at the helm of the ship while the GPS antenna is positioned at the top of the ship. The GPS signals are translated by the chartplotter as longitude and latitude data. This will be shown in the chartplotter's screen. Information that you can see on the screen includes the water depth, environment, obstructions, and other minute data.
Depending on the sophistication of the model, a GPS chartplotter is typically easy to use. A chart display lets you easily plot your voyage. Many units allow you to simply point to a destination and the chartplotter will automatically create the coordinates. A chartplotter should have a keypad so you can easily add coordinates you have determined before.
The display of the chartplotter is very important. It can either be LCD or a full-colored screen. It can be a few inches wide or about a foot in diameter. While more expensive, a full-color display is much preferred because it allows you to view the symbols and information more clearly. Another frequently neglected aspect in buying a chartplotter is its readability under the sun's glare. It's usually pretty bright in the area where you place the chartplotter. Readability under the sun's glare can be a pretty useful feature.
You should be aware that performance is a major consideration when it comes to purchasing a GPS chartplotter. Speed in calculations and redrawing time on the display are factors you should look closely on. You really don't want to wait when you need to look at some critical information.
Chartplotters use two types of charts to present information - raster and vector. Before, vector charts were preferred because of their small size and crisp images. You could place more vector charts in your chartplotter. However, as technology has progressed, the difference between raster and vector charts became negligible.
If you will operate a small boat or yacht, an affordable hand-held GPS chartplotter will usually suffice. These small devices are typically priced at just five hundred dollars. The more sophisticated and mounted chart plotters are for serious vessels. These can be priced up to twenty thousand dollars. Since a GPS chartplotter is such an essential tool, people should not hesitate to purchase an expensive unit if it contains the features that they need.
