Instructions for Using a Maritime Chartplotter

The complete lack of signals and light when night comes makes it impossible to safely sail the seas without getting lost, especially in the case of beginner boaters or those who do this activity in their free time with a recreational purpose. To get from one point to another safely and as fast as possible when you are on the water, you must use a marine GPS chartplotter. Fortunately, the device is not hard to use or understand, so you will not encounter difficulties when it comes to operating it. To find out more about the process of installing and using the chart plotting device, read the following lines.

  • Step #1: First, you must properly install the GPS device. If you are dealing with a marine chartplotter featuring an internal antenna, use it in a boat that does not have a top or cover as the receiver the device features requires a direct line of sight to satellites. If you have an external antenna device, install the antenna on the top of the vessel’s cover for it to communicate trouble-free with the satellites.
  • Step #2: Each marine GPS has its own operational style, so it is important for you to carefully read and get familiarized with the instructions manual of the device. The basic principles of operating marine GPS devices are quite similar, but there are still more than enough differences between the gadgets to make reading the accompanying manual mandatory.
  • Step #3: To see where your boat is located, you need the map to be already loaded on the device. Pick the type of map or chart you like and is compatible with the chartplotter you own, and select the region you are navigating in to receive an accurate visualization of your location.
  • Step #4: Now that you have installed and connected everything, it is time to use the device. On the screen, you will notice a triangle or boat symbol – this is where your vessel is situated in relation to the map. Press the zoom in/out button to get a better view of the map, your current location, and the rest of the areas you want to reach. As you zoom in, details start to be more specific, and you are able to analyze the route better. To mark the destination you want to go to and receive instructions on how to get there, simply move the triangle or boat symbol to that specific destination.
