WHAT TO LOOK FOR WHEN BUYING A CHART PLOTTER & GPS PLOTTER

Chart plotters are essential for fast and safe navigation and are therefore an integral part of every boat owner's repertoire.

A chartplotter is a useful device that helps you navigate at sea, through coastal waters and in inland waters. GPS chartplotters provide accurate location anywhere, anytime. In addition, chartplotters allow you to plan and track your route accurately by providing detailed maps and precise position information.

The following article introduces the different types of chart plotters, including their specific functions and features. In addition, you will learn important factors to consider when selecting and purchasing.

What is a chart plotter?

A chart plotter describes an electronic device that can display detailed maps and accurate position data. Chart plotters are often used by boaters to plan or track their route on the water or on land.

They are used to display important information such as speed, course, depth, temperature and other relevant data. Most chartplotters have GPS technology that can pinpoint the user's position and provide charting and navigation data.

What types of chart plotters are there?

There is now a wide range of different chart plotters for boats. These can be selected depending on the area of application and purpose. The most common types include:

  • Stand-alone chart plotters
    The stand-alone chartplotter is usually larger and more powerful than portable models and has a built-in GPS system.

  • Portable chartplotters
    These models are lightweight and compact, making them easy to take with you. Therefore, they are ideal for boaters and sailors who are looking for a simple navigation device.

  • Multifunction displays
    Multifunction displays offer a combination of chartplotter, radar, sonar, instrument display and other functions. Therefore, they are especially recommended for experienced boaters who need extensive navigation functions.

  • Chart software
    Chart software can be installed on a PC, tablet or smartphone and provides both navigation and charting functions. This option is ideal for people who already own a suitable device and do not want to buy additional hardware.

What features should a modern chart plotter have?

A modern chartplotter should provide accurate boat navigation and detailed chart displays.

GPS system

An integrated GPS system is important to provide accurate position information. A high-quality GPS system enables precise navigation and thus also improves boater safety.

Electronic charting systems should additionally perform a variety of navigation tasks for boaters, such as route planning, track storage, waypoint navigation, tide functions, race tactics and wind programmes.

 

Chart display

A good chart plotter should provide detailed chart displays in high resolution. The ability to zoom and scroll charts quickly and easily allows for effective navigation. The zoom function allows the sea area to be enlarged or reduced in scale and resolution.

Fishfinder with chart plotter: echo sounder

An echo sounder is a technology that is integrated into a fish finder. This is used to detect fish and other objects underwater. A chart plotter is used for the visual display.

Echosounders with chartplotters enable mariners to have a full-fledged fishfinder with graphical underwater display. A prerequisite for this is an appropriate depth gauge. A depth gauge is an important function in a chartplotter, as it informs the captain of the current water depth.

 

Radar, sonar and AIS systems

A modern chart plotter offers a wide range of functions such as the integration of radar, sonar and AIS systems. These features can help you detect obstacles and maintain safe navigation

 

Wireless connectivity

Wi-Fi interfaces, Bluetooth and Wifi functions can be used to ensure functional data transmission around the world.

User-friendliness

A user-friendly chart plotter should be easy to use (intuitive user interface that is easy to understand and navigate). A chartplotter with simple functions and a clear display will make navigation much easier.

 

Connectivity

A modern chart plotter should also be compatible with other devices: In the digital age, you should be able to connect it to your PC, tablet or smartphone. This allows easy transfer of data and provides additional functionality.

Which interfaces are particularly important?

NMEA 0183 / NMEA 2000 / Seatalk / Seatalk Ng are standard interfaces for the transmission of data between electronic devices on board a vessel. Ethernet and USB ports allow the chartplotter to be connected to other devices on board (e.g. computer or radar). WiFi ensures a wireless connection to mobile devices or a wireless network on board for downloading updates or synchronising data.

Modern chartplotters should have the following important interfaces:

  • NMEA 0183
  • NMEA 2000
  • Seatalk
  • Seatalk Ng
  • Ethernet
  • USB
  • WiFi

Which systems can be connected to the GPS chartplotter?

These systems and devices can be connected to a GPS chartplotter:

1) Radar

For a comprehensive vessel monitoring system, a radar system can be linked to a GPS chartplotter. This can be used to monitor both the vessel's location and its surroundings. Warnings of hazards such as reefs or shoals can also be easily detected this way.

2) Autopilot

A GPS chartplotter can be linked to an autopilot system to allow the vessel to steer automatically. This makes the vessel's voyage safer and more comfortable as it can maintain the vessel's course without human intervention. Linking to an autopilot system gives the GPS chartplotter additional functions such as detecting navigational objects and displaying weather forecasts.

3) AIS (Automatic Identification Systems)

By integrating AIS with a GPS chart plotter, vessels can be tracked and identified in the vicinity. This can reduce the risk of collision by continuously monitoring a safe position in relation to other vessels in the water. In addition, AIS systems can also provide information on the position, speed and course of one's own vessel to facilitate navigation.

4) Sonar and fish finders

The integration of sonar and fish finder systems with a GPS chartplotter enables precise location of fish and underwater obstacles. This makes fishing or navigation in unknown waters much easier. In addition, the combination of GPS and sonar technology allows for precise charting and navigation that can be quickly and easily adjusted to suit individual needs.

5) Weather information systems

A GPS chartplotter can also be linked to weather information systems. This allows boaters to get up-to-date weather forecasts and information. This is particularly useful for long-distance and offshore cruising, as it gives boaters a better idea of current and future weather conditions

6) Entertainment systems

You can also connect your GPS chartplotter to an on-board entertainment system. With this connection, you can enjoy music, videos and other media content while you drive.

Are there any existing devices that can be connected to the chartplotter?

In fact, there are a variety of devices that you can connect to a chartplotter to enhance or improve functionality. Here are some key interfaces and devices that should be compatible with a modern chartplotter:

  • Radar (increase visibility on the water and detect obstacles)
  • Autopilot (automation of navigation)
  • AIS (detection of vessels in the vicinity)
  • Sonar (depth and structure of water)
  • Mobile devices (connectivity with smartphones and tablets to synchronise data and charts in real time and enable remote control functions)

What does a chart plotter cost?

The cost of a new device always depends on what your needs are and what features are important to you. Therefore, the cost of a chart plotter can vary greatly depending on the brand, model and functions. You can get basic echo sounder chartplotters from around £250, while you will need to budget considerably more for high-end, powerful models with comprehensive features and a large display.

The cost also varies depending on display size, connectivity options, sonar functions, integrated maps and the other facets shown. Therefore, it is important to initially set a budget and then decide which features and functions are most important for your application. This way, a sensible investment can be made.
