How to Choose a Best Marine GPS Device?
Deciding what model of a marine GPS device to buy can be difficult especially with so many models on the market ranging from simple ones to full-sized navigation systems that cost at least several hundred dollars. However, the process of choosing the best marine GPS device does not have to be that complicated if you decide what exact features and functions you want to see in your marine GPS device.
Hence, before you go out shopping for the best marine GPS device ask yourself several questions such as how many satellites you want your marine GPS device to use? Normally, an average priced marine GPS device will use around 12 satellites however the most premium ones will likely use all 24 satellites that are available in the GPS system.
Secondly, decide on how large you want the screen to be but remember that large screens are much easier to read from a distance. This can be especially useful with models that show sea and lake beds as a large screen can be used to see any large rocks on the path that could cause potential hazards.
Thirdly, most marine GPS devices will be portable however some upscale models might be too large and heavy to be carried around. Moreover, think about whether you want your marine GPS device to have the ability to connect to computers. This function will be mainly needed to save important data such as waypoints, usual routes and any maps.
Also, if you will be willing to spend a couple of extra hundred dollars then you could get a marine GPS device with an external antenna that would provide the extra reception needed for better signal, more accurate forecasts as well as better mapping of the area.
Frequently Asked Questions (FAQs)
Q: Do I Need a Marine GPS?
A: Getting a marine GPS depends on your activities out in the open sea. If you plan to voyage pretty long distances in the open ocean, a marine GPS is necessary. It is quite easy to become disoriented and lost in the vast ocean. Having a reliable, modern GPS can guide you to your location with ease.
Not only can a marine GPS help you orientate yourself in the open sea, but it can also help you find valuable fishing courses. Modern GPS can also come with fish finder software. These will tell you where fish tend to gather and have built-in features such as maps of coastlines, rivers, and lakes. This makes the marine GPS a valuable piece of equipment to have on board.
Q: How Accurate Is a Marine GPS?
A: Modern GPS technology is highly accurate. However, it needs to have favorable atmospheric conditions to work correctly every time. GPS communicates with various satellites in low orbit, so having great weather won’t interfere with that connection.
Other factors such as tall buildings or densely populated areas can also affect the GPS’s performance; however, both of these aren’t a problem out in the open sea. Marine GPS is commonly used by the military, such as Coast Guards, because of its accuracy and reliability.
Q: What Is the Difference Between a Chartplotter and GPS?
A: When searching for a GPS, you might’ve heard of the term “Chartplotter.” The difference between a Chartplotter and GPS is that GPS will provide your location but doesn’t apply it on a map. Meanwhile, a Chartplotter will take the location provided by the GPS and apply it on top of a map. In short, all chart plotters are using GPS, while not all GPS are chart plotters.
A good and reliable marine GPS is crucial for safe marine journeys because there are no directional signs of any sort on the water plus without a marine GPS system boaters could potentially get lost and even die out at sea. Once you buy your marine GPS device make sure that you correctly install it and pay attention to whether your marine GPS device has internal or external antennas as the installation process will slightly differ between the two.
Moreover, GPS devices with internal antennas are more suitable to be used on open boats without a roof or tent cover as the satellite receiver will be much weaker in such models. On the other hand, GPS models with external antennas will need to be installed on top of your marine vessel cover and will need to be wired to the console and the receiver separately.
Also, think about downloading and installing a regional map as it will contain far more details than a general world map will. Plus stock up on batteries if your model of choice operates on AA batteries or ensure you have a reliable battery charger on board. You wouldn’t need to buy an expensive carrying case, just one that is made from durable material and thick enough to prevent scratches occurring on the marine GPS.
Look for marine GPS devices that come with a warranty and an adequate exchange window too as this will give you a chance to return the product if for some reason you will not like it. With all this information presented to you, we hope you now know how to select the best marine GPS device that will be durable, reliable and will serve you for years to come.
