Also, this product has a C-MAP easy routing and Avionics charts which will show you not only the shortest course to your waypoint but also which way to go to avoid any potential dangers like landmass or shoals. But the navigational hazards feature is not pre-installed so you will have to buy some new charts for this. Yet, the GO7 SXR has a radar input and thanks to the NMEA 2000, you can take control of your vessel’s motor, check the fuel level, flow meters and many more. And the best thing is that you can do this via your phone, using the Go Free controller app.

A Few Words About The Types That You Really Need To Know

Marine GPS Chartplotter ReviewsUnless you are a compass pro, then you definitely need a chartplotter to help you navigate in the open sea. But what does it make this device so useful and helpful? Well, imagine you have only a GPS system in your boat – you will see the coordinates of the place you want to go, but they will be shown in numbers. s

And if you have skipped Geography classes, the latitude and longitude coordinates will not be familiar to you at all. So, here comes the pivotal role of the chartplotter. This unit is an excellent combination of a GPS system and an optical device through which you can actually see where you are positioned on the map shown on the chartplotter’s screen.

Hence, you can no longer be lost in numbers or coordinates because they are going to be accurately plotted on your device so that you can easily read them and go sailing with confidence.

However, chartplotters come in different types, and this is perhaps what will make you feel confused when considering buying one. For this reason, our team has compiled a list with the basic models that you may come across on the market as well as their main features and characteristics. And remember that the more advanced the technology is, the bigger the price you will pay for such sailing electronics.

1.     Handheld Chartplotters

This type of devices for marine navigation has the option to be placed anywhere, and as their name gives it away, you can hold them in your hand. They come with internal GPS and are small in size which makes them very compact to use while sailing or doing watersports. Handheld chartplotters have all the essential functions which will be enough for you to determine your position on the map and mark your waypoints. In addition, these units are equipped with integrated maps although not that detailed as you may wish for.

Still, all handheld chartplotters’ manufacturers offer a wide variety of lake or sea maps to be downloaded or bought separately as an add-on to your unit. And one more thing – since the screen of such products is small, you need to pick a handheld chartplotter with very bright colors and screen protection from direct sunlight.

2.     GPS Marine Chartplotters

The second type is also basically like the handhelds, but the difference is that its screen is bigger than the former’s. Therefore you will not find it very comfortable to hold it or mount it on your kayak, so such guiding navigation is more suitable for bigger boats and not intended for water sports. However, GPS Marine sailing electronics may come with so many features such as additional maps, options to save waypoints and routes, barometric altimeter and a built-in compass. In short, this is all you need for a weekend sailing.

3.     GPS Chartplotter With Built-in Fish Finder

Now, this is what every fisherman would like to have in their boats. This type of device has the same characteristics as the basic GPS Chartplotter, but there is a built-in fish finder. You will definitely like this extra since it sends sound waves into the subsurface and then turns the signal into a picture to be shown on the screen of your chartplotter. This way you will easily find the perfect fishing spot without wasting your time and your boat’s fuel. Another thing is that you can upgrade such steering navigation with a sounder when you buy an additional antenna for the weather or radar. Also, some models come with a transducer, but if this is not the case with your chosen model, you can always purchase such separately.

4.     Network Chartplotters

As the name suggests, this is a high-tech navigation device designed to provide you with the most accurate information of the sea bottom as well as give you full control of your boat. Usually, network chartplotters have built-in internet connectivity so that you can use your marina’s Wi-Fi or tether it to your smartphone. This way you will get not only an accurate picture of your target place and your route, but also be alerted of possible dangers under the water. Also, the operation systems of network chartplotters are exclusively user-friendly and very advanced, so you will really like all the extras it has to offer like controlling your boat motors, water temperature feature, free Cloud services and even listening to music.

5.     Network Chartplotters With Built-in Fish Finder

These types of marine navigation systems are again aimed to aid fishermen, but since it is cutting-edge technology, you will undoubtedly enjoy the 2-dimensional image of the sea bottom on the screen. This way, your fishing trips will become even more productive and satisfying.

What To Look For In A Marine Chartplotter

In this section, we are going to list some of the features that may come with your chartplotter or be purchased separately to boost your navigation device’s performance. We have included some basic information on each one’s purpose and functions as well. This way, you will no longer hesitate what the most useful feature for you and your sailing activities is.

1. Transducer

Some marine chartplotters are sold with a transducer while others are not. But in either situation, you need to know why a transducer is so important and what type you need.

Transducers actually serve as an antenna for your boat sonar’s system. The electrical signal that comes from the sonar is turned into a high-frequency sound which is then sent into the water’s subsurface and when it reaches the bottom or any other object like rocks, for example, the signal returns. At this very moment, the transducer receives the incoming signal and turns into a frequency which can be read by the sonar. And this is how you get the image of what is under your boat.

The transducers that come with chartplotters will be efficient because you will not waste your time and money in searching for any additional devices. Also, this tool for converting electrical signals will help you when you go fishing or when sailing in unknown waters.

2. Chirp Sonar

This feature is excellent for giving you an accurate image of the sea bottom in terms of depth and resolution. And thanks to the fact that this type of sonar transmits and receives signals in more than one frequency, you can quickly tell apart big fish from smaller ones for instance.

Also, if your marine chartplotter is equipped with Chirp sonar, then the chances of you receiving misleading information from the sea bottom are minimal. The reason for this is the ability of the sonar to tell the difference between true sonar echo and disturbances.

In addition, there are different frequency ranges for the Chirp sonar that can be exceptionally functional depending on where you sail. And this is crucial when you want to cast your anchor successfully. So, do not miss out our best boat anchors thorough guide along with our top picks to help you choose the right device for mooring your vessel.

·       Low Chirp Frequency

Here the signal is transmitted at 25-80 kHz or 50 kHz, which means that such signal will be excellent for sailing in really deep waters – more than 196 feet.

·       Medium CHIRP Frequency

When the frequency is between 80-160 kHz or 83 kHz, then you can easily find great fishing spots in shallow waters.

·       High CHIRP Frequency

At high frequency like 160-800 kHz or 200 kHz, you will definitely get the highest resolution. Moreover, if your vessel is sailing fast, the high chirp frequency will be able to show you whether there is fish or other objects under the water. Also, such a frequency range is most suitable for water depths of up to 196 feet.

3. Maps

No matter whether you are sailing in the sea or fishing in a lake, you need to know your exact whereabouts. This is why maps are of great importance, and all chartplotters come with preloaded ones. However, the in-built maps are usually too general, and very often you will not find your preferred fishing spot there. Or, if sea adventures are your thing, then all of the places you have never been to will not be installed in your steering navigation system. But this does not mean that you cannot get the map you want, it is just that you are expected to buy anything extra from the manufacturer.

So, when picking a marine chartplotter, make sure to get all the details about the preloaded maps and all the charts that do not come in the package.

4. Mounting Hardware

Although not a feature of the chartplotters’ electronic characteristics, positioning your device the right and safe way is vital. We advise you to check your boat’s dashboard and think how to mount the chartplotter since some vessels ‘panels with controls are not conventional.

Also, make sure to research the material of the mounting bracket. If plastic is mainly used, then you will have to buy a new product for securing your chartplotter as this material is not durable at all.

5. Screen Brightness Display

When choosing your perfect device for marine navigation, do not forget to check whether there is protection against direct sunlight. It is also essential to pick a product with extremely bright color options to get a clear view of the images on your sailing electronic device regardless of the weather conditions.

Marine Chartplotter Installation Tips

Marine Chartplotter InstallationIn case you wonder how to put your marine chartplotter into use on your boat’s dashboard, here are some pieces of advice to help you with the installation. However, remember that different models may require some adjustment to fit in. Also, not all electronic devices come with the mounting hardware and what is more, if the transducer is included in the package, you will have to fix it, too.

Here we will give you a step-by-step guide to installing a basic model navigating device.

  1. Choose the place where you will mount the chartplotter and make sure it will fit. Sometimes this is a challenge, especially when you have to consider the protection of the device as well as the viewing angles.
  2. After deciding on the most appropriate place, drill the 4 holes for the mounting studs. You should make a hole in each corner to match the device’s chassis.
  3. Run the cables for the chartplotter before you actually position it.
  4. Then you have to reach in behind to fix the thumbnuts to secure the unit.
  5. Place the helm panel and after that turn on the device for testing.
  6. Insert the chart data card (if you have such), and your chartplotter is ready to navigate.

Finally, do not forget to read the manufacturer’s installation guide for more specific details on your marine steering device.

Maintaining Your Marine Chartplotter

Any device needs proper care, and the same goes to chartplotters. And given the fact that you will use this device in any kind of weather conditions and in a variety of situations, you need to know how to keep it safe. So, here are some hot tips about maintaining your fish finder.

1. Screen

Taking care of the visible parts is a must. And the screen is the most important here. Make sure that:

  • You clean it with a soft cloth or a PC screen cleaner
  • The back of the chartplotter is sealed against the pod; otherwise, the device will not be water-resistant.
  • You do not use abrasive or solvent-based cleaners.

2. Software Updates

Updating your marine navigating device is essential because it can give you the latest information about the weather, currents, tides and many more. Make sure to call a technician or contact the manufacturer if any problems occur when the image is blurred on the screen, for example.

3. Replacing instruments

Sometimes you will need to make some changes to your chartplotter device either due to upgrades or any troubleshooting features. In these situations, it is crucial to take into consideration the following tips.

  • In case your display has been cracked, or your transducer is not working, and you have to replace them, remember to contact the same device’s manufacturers.
  • If you cannot find a replacement for your chartplotter model because your navigation system type is no longer in stores, then you still have some options.

A- If the part that you need is a stand-alone instrument and it is not connected to any network, then it is going to be easy as any piece can fit.

B- If the part is networked with others, then you will have to check whether your device is equipped with a standard NMEA output. Remember that your new instrument must use the same protocol to make it work but make sure you get some extra cables, just in case. Also, a data combiner will be a great idea since some NMEA protocols have a limit to the number of instruments.

Marine Chartplotter Safety Tips

Buying and installing your electronic navigation system is just the beginning of your sea adventures. But if you are not aware of the possible dangers or do not know how to work with your chartplotter, then any voyage will turn into a nightmare. This is the reason why we have prepared some essential tips to ensure safe sailing.

  • Navigation systems are essential, but they are made to assist you, so do not rely only on your chartplotter. You really need to have some basic navigation knowledge and know your boat.
  • If you are going to use a map which is on an SD card, make sure that the map is up-to-date. This way you will have the latest information about all the possible dangers that you may come across.
  • It is vital to study and understand all the symbols that you will see on your device’s screen.
  • When plotting your course remember to check what is standing between you and your destination because your chartplotter will show you the shortest way but not the hazards you may come across.
  • Make sure you plan your route carefully and understand where exactly you are going. You can get an excellent helper when looking at what is in front of your vessel in the far distance if you have binoculars. So, do not forget to check out our best marine binoculars top picks and extensive buying guide to aid your navigation.
  • Some models for marine sailing navigation will let you zoom in and out. Although this is a helpful feature, you really need to use the largest scale zoom possible so that no functions are lost during this option.
