Types of Marine GPS

Before you pay for the best marine GPS for the money, it is ideal to learn more about the product. Basically, there are different types of the tracking device. Given below are the following, which could also help narrow down your choices:

1) Fixed Mount Units – From the name itself, it will be fixated on the fleet. It comes with a mount, which helps in the installation of GPS in your fleet. However, take note that once installed, it could no longer be removed.

There are large GPS units that could be mounted on your fleet, which have an average size of approximately seven inches. Most of the fixed mount GPS units today feature a touchscreen. Many prefer this for professional use since it could serve as an all-in-one device.

It may also be linked with radar and sonar. For it is packed with a lot of features, expect that it is offered at a considerably higher price.

2) Handheld Marine GPS – This is an in-demand type of GPS since it is handheld, which means you could carry it anywhere when you are not on board. Besides being used for marine purposes, you might as well use it to track locations when cycling or hiking. Obviously, the maps will be more different since these will be in marine charts.

It will likely have a smaller screen due to its reduced dimensions. When you are not steering, it is a great device to use on other boats. Since it is battery-powered, you do not have to worry about plugging it elsewhere.

However, this may not be the great choice for others who are looking for more features. It may also not be as versatile as its counterparts. The smaller screen also makes reading and positioning more difficult.

3) Portable Marine GPS – This is considered to be the most versatile, but not as filled with capabilities as the first. It is almost similar to the appearance of GPS in cars. At present, most of the portable marine GPS devices also feature a touchscreen interface.

Physically, the device could be too large to hold despite its “portable” description. People choose to mount it instead. Nonetheless, it is a target of most theft since it could easily be removed.

The larger display makes navigation easier. You may even use it on the road. Depending on the model or brand, it may also connect to sonar.

What to Look For When Buying

Your choice of boat navigation system must comply with your preferences for personal and corporate use. Remember, not all GPS trackers are meant to be used off the road. Moreover, there are products that have limited features.

To ensure that you will get a device with a full package of capabilities, you should verify its features. You may consider the following while choosing a product from your shortlisted options:

1) Number of Satellites – You must determine the number of satellites a marine GPS tracker uses. The key is to find a device that could at least connect to 12 satellites. This is a customary that makes a navigation system worth the buy.

The more satellites are synced into the marine GPS device, the more accurate it is. At present, a unit could be considered high quality if it uses all 24 GPS satellites.

Screen Size. The smaller the screen size is, the more difficult it is to navigate the maps. You have to read coordinates and layouts at the same time. If you do not want to make incorrect assumptions, look for a bigger screen.

Marine navigation involves studying the lake bed, shallow areas, and all of the rocks you could see. By having a bigger interface, you could see everything.

2) Sonar Capability – It is a must to find a GPS tracker that has sonar on board. Otherwise, it must at least be able to link to sonar. There are new models that utilize WiFi to display sonar on both smartphones and tablets.

3) Portability – You do not necessarily have to settle with a handheld device given it has a smaller screen although it could be useful for other applications. If you use the GPS tracker for professional purposes, look for one that is mounted on a fleet with a bigger screen.

4) Computer Connection – The GPS device is also more ideal if it connects to a computer. You need this in order to either save or have a backup of maps, routes, and waypoints. Through the connection to a PC, you could also purchase or download extra maps when needed.

5) Marine Charts – There must be nautical and optional charts available in the device. Usually, upon purchasing a device, the bundle includes the basic marine charts. However, if you need optional ones, you may as well get the highway maps for road use.

6) Safety Features – You should not forget how useful safety features are. Among these attributes is a 12-channel receiver, which allows you to receive a signal when you are offshore. Moreover, you have the arrival alarm you will know when to run up onto the dock.

Collision alarm is also valuable since it could give a warning if the fleet is close to an object that may result to accidents. Low-battery alert is also helpful, particularly if you need to replace batteries. Also, you have the Man over board (MOB) feature, which gives the boaters idea the location of an incident to be attended urgently.

Usage Safety Tips

After getting your best GPS for boats, you also have to learn how to use it properly, particularly if it is your first time. There are cases you may also need a refresher even if you have been utilizing navigation systems previously. At present, GPS systems for marine use are becoming more complex due to added features.

To get the most out of the product, here are professional tips that will help:

1) Install the Device Properly – Installation of the device gives high consideration on the antenna attached to the GPS tracker. There are units with external antennas, whereas the rest have internal ones. The fixation of either of the two varies.

If you are dealing with a GPS for marine use having an external antenna, you need to ensure that the device is installed on the boat hard cover’s top part. There must also be a direct site line to the satellites it is connected to. Moreover, it must be linked back to the console and receiver.

2) Test the Reception – Signal reception has always been an issue in using GPS devices. It is necessary to test your device for good satellite connection. This must be done in the fleet where it will be used.

In case there is a poor connection, you may purchase a separate antenna. This is a proven way of improving the signal reception to the satellite.

3) Familiarize Yourself – Before you even use it in actual operations, you should not forget to read the manual. This is imperative so you will not miss understanding the added features of the product. Chances are that newly bought GPS trackers have additional capabilities.

Reading the manual will not only help you use the device. Instead, you will also have improved knowledge on the terms used in marine navigation.

If you are a beginner, you could start with the basics. For instance, you have to be aware that a triangle or boat symbol represents your vessel. From this simple information, you will have ideas of its distances to other areas and related coordinates.

4) Verify the Maps – You should not depend on the preloaded maps in the device. This is the case even in products with a worldwide basemap. It is still necessary to check if the maps give you details of the regions you need to work on.

5) Try Getting More Charts – There are charts downloadable from the web, which will provide significant value to your navigational needs. Most of the time, you could get the other charts in the official website of the provider or manufacturer of the device.


There may be tons of high-quality marine GPS trackers available on the market apart from the ones given above, but Garmin eTrex 10 Marine GPS is obviously the most recommendable one. It comes from the trusted GPS producer, Garmin, and has a noteworthy larger internal memory feature, which is unlikely in portable GPS trackers. Besides, it is offered at a considerably lower price, giving beginners a taste of great quality device.

Otherwise, you may check out another product. It is normal that every system could provide satisfaction to its users. There are cases that one may prefer Garmin trackers, whereas others do not.

Ultimately, if you find the selection generally perplexing, you should choose a product that meets your needs ultimately.
