Today, navigation is going through a revolution due to marine GPS units. This global positioning unit is useful for both beginners and experts. These devices allow you to track coordinates when you are in the water. You can easily navigate without worrying about getting lost. As a result, you can enjoy smoother navigation since you won’t need maps and the like.

Marine GPS units offer many features. In this article, we are going to talk about some important factors that can help you get the right unit.

1. Connectivity to Multiple Satellites

First of all, it is important to note that these units connect to a minimum of 12 satellites in order to work properly. This is important for accuracy. A high-quality device makes use of all 24 satellites to offer the best service.

2. display screen

If the GPS unit has a large screen, it will be easier for you to read the screen. Additionally, some units can read the layout of the ocean or lake bed. This way you can know the location of the shallows and rocks in the sea. If the screen is big enough, reading all this information will be much easier.

3. Portability

Depending on your personal preferences, you can opt for a large or portable unit. Portable models are also available. Again, these devices are safe and convenient since they are small. However, it is important to note that handheld devices do not have many mapping features. In addition, they have a small screen.

Larger units offer a larger screen and many features. For example, you can see everything without problem on an 8-inch screen. These removable units are easy to place in any vehicle when not in use.

4. Computer connectivity

GPS systems allow you to save different types of information such as waypoints, maps, and routes. Apart from this, you can also download additional maps. To access this data, make sure your device can connect to a computer wirelessly or via a wire.

5. Antenna port

Many GPS units have built-in antennas. They’re compact but not impressive when it comes to reception. Therefore, you may want to opt for a device that has an external antenna. Alternatively, you can get one that comes with a port for antenna installation. With good reception, you can enjoy more accurate forecasts and maps.

6. Voice activated

Sometimes navigating requires you to get help from other peers. For this purpose, you may want to get a device that can receive verbal commands in addition to manual commands.

7. Waterproof

Most GPS systems are waterproof. But it is important to note that they are not completely waterproof. When it rains heavily, the unit is likely to get wet. Therefore, you need to invest in a device that is 100% waterproof.

8. Mapping system

As far as the mapping system is concerned, marine GPS units come in three types. Each type has many features; however, all of them have at least the basic features.

So be sure to consider these features before purchasing a unit.
