Marine navigation has evolved significantly, making traditional paper charts and compasses a thing of the past. Today, chartplotters powered by GPS and sonar technology provide a more reliable and intuitive navigation experience, ensuring safer and more efficient voyages. Whether you're an experienced sailor or an amateur exploring the ocean, choosing the right chartplotter is crucial to enhancing your boating experience.

But with a wide variety of chartplotter models available on the market, how do you know which one to choose? Selecting the best unit can be overwhelming, from high-resolution displays to integrating with radar, AIS, and fishfinder systems. In this guide, we’ll explore what a chartplotter is, its key capabilities, and the best products to help you navigate accurately with the clearest navigational information available.

What is a Chartplotter?

A chartplotter is an electronic navigation tool that combines GPS data with detailed maps, allowing mariners to determine their location in real-time. It is an essential tool for sailing, fishing, and commercial vessels, offering precise positioning, coverage, and route planning capabilities.

Innovative chartplotters—such as the Garmin chart-plotters, Raymarine Axiom, and Simrad NSS, integrate with radar, AIS, and VHF systems to enhance situational awareness, incorporating maritime security technologies for safer navigation. Many versions, including those from Furuno, Lowrance, and Humminbird, feature versatile capabilities, such as echosounders, transducer integration, and sharp color screens.

For boaters looking for high-end electronics, companies like Navionics, Echomap, and NavNet provide cutting-edge solutions for reliable maritime navigation—whether you need a compact chartplotter/fishdetector combo for a small boat or an advanced detector/chartplotter system for commercial use, there are plenty of choices to select from.
