Choosing The Best Marine GPS: Simple Guidelines

Choosing The Best Marine GPS: Simple Guidelines

There are specific guidelines when it comes to choosing a marine GPS. Sometimes, these specifications can be intertwined with fish finders and GPS combos. The point here is that you don't want to buy any GPS device without looking at the considerations. Otherwise, it would be troublesome on your part.

Number Of Satellites

These GPS devices don't work like magic. They cannot locate or map the area you are in if there is no assistance from satellites. That's the very reason why GPS doesn't work if there is no satellite coverage. It is deeply dependent on the availability of the satellite and its distance as well.

Most of the GPS manufacturers claim that their devices are supported by a myriad of satellites. Typically, the number of satellites that the GPS can connect is around twelve to twenty-four.

Of course, the idea here is that you need to seek a GPS device that is connected to as many satellites as possible. The higher the number of data sources, the more accurate the information that these GPS devices can create. Accuracy is always essential when it comes to GPS devices. Therefore, this aspect should never be ignored.

Fortunately, marine GPS will only require a minimum of three satellites so that they can operate properly. They are already sufficient enough for navigation purposes and determining your location.

Size And Design

There's no such thing as a one-size-fits-all when it comes to GPS devices. Even the manufacturers of marine GPS units like Garmin and HELIX have their creations vary in size, shape, and style. You might have noticed it on the previous section where I listed some of the best marine GPS today.

For marine applications, you can opt for handheld GPS. The latter often run through the help of 12-volt batteries. They are great for every adventure that you have in seas and oceans. There's no need for you to stay in one place to check your current location. Anywhere in the boat, you can bring these handheld units with you. Because of their small size, some handheld marine GPS can fit in your pocket.

The only thing that you need to be wary about them is their battery life. Their compact size also limited their power capacity. They can't last for extended periods. You need to charge them from time to time.

There are dash-mounted types of GPS devices as well. They are great if you prioritize power and functionality. Compared to portable units, it is undeniable that these larger GPS provides better ergonomics and features. They have larger screens, and they can provide a myriad of data that could help you navigate the waters better. Their trade-off is their cost. They are generally more expensive than portable units.

Here is a guide on how you can install fish finders, GPS, ahd chart plotters in your boat:


Sure enough, you will need a GPS that has excellent defense against the water. Always keep in mind that not all GPS out there are designed to tackle the rough environment and erratic atmospheric conditions. Since you are taking the GPS in the oceans, you must have a sufficient defense against water and moisture. If possible, the construction should provide resistance against abrasion and corrosion as well.

The ideal GPS for a marine application is a unit that offers an IPX7 waterproof rating or higher. Such a rating ensures that the device will not get damaged even if it has been submerged in the water.

Speaking of, it would also be great if the GPS can actually float in the water. Buoyant GPS devices are indeed better because they give you an assurance that you won't be buying replacements anytime soon.

Bottom Line

It is beneficial for your boats to be equipped with the best marine GPS. This device alone can ensure that you won't waste your time wandering in the water without getting any yields.

Fortunately, the GPS units are no longer expensive as it is used before. Anyone can get them now because they are all manufactured commercially. In your next fishing and boating adventure, better have them!

That's it for now. If you have queries about fishing and water-related amenities, feel free to ask me below.
