What is Marine GPS?
A Marine GPS is one that is pre-loaded with nautical maps to facilitate easier and more precise navigation. In fact, you can even choose one depending on the region that you sail in, whether inland or coastal. Moreover, if you lost your way while sailing, you can even send signals to the rescue team.
Why do You Need a Marine GPS?
A lot of people presume that they can use just about any GPS while sailing, but this is a wrong notion. Although your car or trekking GPS works on satellite-based technology and should practically work just about anywhere, a Marine GPS does the same and much more.
The core reason to go for a Marine GPS is that this device comes with several additional features such as pre-loaded nautical maps and sonar. Most GPS have regular updates on additional maps and routes, making it more useful and up-to-date.
What to look for in a Marine GPS
Although any GPS would work, but it would do just a fraction of what a Marine GPS can. Therefore, you must look for an advanced Marine GPS irrespective of its price. That’s because a Marine GPS is meant for your safety and even the best of Sailors can at times, lose their way. Below-mentioned are some features that you must look for while buying a Marine GPS.
Nautical Maps – In order to sail safely, you need to sail in the right direction without losing your way. Most advanced Marine GPS not only facilitate navigation, but also provide the required calculations to reach a particular destination. Moreover, the pre-loaded nautical maps and their timely updates are the very reason that most Sailors specifically look for a Marine GPS.
Sonar – Most of the sophisticated Marine GPS have sonar that locates fish or oyster beds. Also, it is highly recommended that you invest in a highly advanced GPS because it is a safety device, and when it comes to safety there should be no compromise.
Large Display – You must always remember to buy navigation devices that give you a clear view of what’s in store for you. This may not be possible if your device’s display is not large enough.
Antenna – If you are buying a smaller Marine GPS then pick one that comes with antenna. This is extremely useful while sailing because at times the signals can be extremely low.
Signalling Rescue Teams – The recent Marine GPS devices have the option to connect with the nearest rescue teams and send out signals for them to locate the victim ship. This is definitely a must-have feature for those who sail longer distances.
What are the different types of Marine GPS available?
Marine GPS can be classified into three groups based on their sizes, these include Handheld, Portable and Fixed-Mount GPS Systems.
As the name indicates, a Handheld Marine GPS is a compact device that can be held in your hand. It is easy to carry and considered to be the most ideal for those who sail shorter distances. It is recommended that you use a handheld Marine GPS only to navigate to places that you are familiar with. One must keep in mind that sailing is not like cycling or trekking where you should be particularly looking out for compact GPS systems. On the contrary, for a better view and detailed navigation instructions, you must always consider a GPS system with a larger display. So, if you are keen on a handheld Marine GPS, then always remember to get one with an antenna for better signals in low signal zones.
- Compact and easy to carry
- Often the cheapest of all types of marine GPS Systems
- Mostly lacks additional features that other marine GPS systems offer
- Some of them come with an antenna for better signal
- Can be used in multiple boats

These are the most preferred category of Marine GPS Systems that have a larger screen than the handheld GPS. This is quite similar to the ones you see in your car and is supposed to be mounted on a temporary mount. The portable GPS are also called as chart plotters and are lesser expensive than the fixed mount marine GPS Systems.
The portable marine GPS are considered to be the most convenient type of GPS because they enable better navigation and also are affordable. These are far better than the handheld GPS because you don’t have to struggle to get a detailed view of the map. However, if you plan to use it in two boats, then you must find a model that is easy to screw and unscrew, and also buy an additional mount for the second boat.
- Easy to Mount and dismount
- Ideal to use in multiple boats
- Larger screen size as compared to the hand held GPS systems
- Often comes in a touch screen form
- Often comes with additional features such as the fish finder
- Higher risk of being stolen since it is easier to unscrew
These are the most expensive Marine GPS systems that come with fixed mounts and are great from security point of view. That’s because the chances of theft is lowered because it is not easily detachable.
- Larger screen ensures better visibility
- Lesser chances of theft as it fixed
- Mostly comes with additional features like sonar and radar
