There is so much to love, and learn, about boating. That's why we created this library of articles, videos and blog posts to help you throughout your adventures.
The Benefits of GPS
GPS stands for Global Positioning System.
GPS units receive signals from satellites that determine location. Depending on the unit, a GPS can pinpoint your position in up to three dimensions—latitude, longitude and altitude.
The remarkable thing about GPS is that the satellite navigational information is available to anyone, anywhere, free of charge. Of course, you need to buy a GPS receiver to use the data, but it’s a pretty small investment when you realize how much information you can get.
Let’s talks about the types of GPS units available.
Battery-operated, hand-held GPS is ideal for small boats, because it doesn’t need to be mounted and won’t take up valuable console space.
Mountable or portable GPS receivers have larger display screens, bigger buttons and more features than hand-held units. Most GPS in this category operate on batteries or external 12-volt power. They come with brackets to hold the GPS in place while you’re underway and can be removed for safekeeping when you’re done cruising.
Fixed-mount GPS receivers offer the largest displays and the most features. They’re meant to be installed permanently.
A stand-alone GPS is often referred to as a chart plotter. Many fixed-mount GPS units combine satellite navigation with fish finding functions.
Most GPS units come with basic maps pre-installed. To boat safely make sure that you have the latest navigational information for the areas where you are boating, whether that is charts or electronics. These are changing all the time so be sure you have the most current data. To expand your GPS’s knowledge base or access detailed regional data you can purchase and download maps from CD-ROMS or data cards.
GPS offers almost endless possibilities for high-tech boaters. In fact, the technology to network a GPS with radar, sonar, VHF marine radio and a boat’s autopilot system is already available. GPS is a wonderful tool. However, like any piece of equipment a GPS unit isn’t perfect—you should also learn how to navigate with a compass and chart, just in case. It’ll give you more confidence to explore and make the most of your time on the water.
