10 Best Chartplotters 2026 in the United States

The Garmin ECHOMAP Ultra 2 12-Inch 126sv Chartplotter is a solid choice for those seeking a reliable chartplotter for both US and Coastal Canada navigation. It features a substantial 12-inch touchscreen display, which offers ample viewing space for charts and sonar readings. The touchscreen interface is generally intuitive, making it easier for users to interact with the device, although some may prefer physical buttons for operation. Garmin’s Navionics Plus Mapping provides detailed and accurate cartographic information, enhancing navigation reliability.

Additionally, the inclusion of LiveScope live-scanning sonar benefits users interested in fishing, providing real-time underwater viewing capabilities. However, it's important to note that the transducer is not included, which will require additional purchase for full sonar functionality. This product is battery powered, which can be convenient for portable use, though users should ensure they have a reliable power source for longer excursions.

In terms of connectivity, the chartplotter supports various options, allowing integration with other devices and systems on-board, which is a plus for tech-savvy users. The product's durability is supported by its solid construction, although given its size and weight, careful mounting is necessary to prevent damage during use. This chartplotter is well-suited for individuals who prioritize a large, responsive display and advanced sonar features in their marine navigation toolkit, although the additional purchase of a transducer is an essential factor to consider.

The Simrad NSS9 evo3S is a feature-packed 9-inch chartplotter that caters well to boating and fishing enthusiasts. The high-definition LCD screen offers clear visuals, making it easy to read charts and sonar images. The device’s new iMX 8 high-performance processor ensures quick response times and smooth transitions between screens, which is crucial for real-time navigation and fish finding.

The built-in GPS is reliable and comes preloaded with C-MAP US Enhanced charts, covering both inland and coastal areas, which adds to its versatility and ease of use for different water activities. Connectivity options allow integration with various systems on the vessel, including monitoring engines and controlling the onboard sound system.

The user interface is intuitive, with the ability to switch between a responsive touchscreen and a physical keypad with a rotary control dial, accommodating different user preferences and weather conditions. On the downside, the product's relatively high price and moderate best-seller rank might deter budget-conscious buyers. Some users might also find the weight (8 pounds) a bit cumbersome for smaller vessels. However, its robust build promises durability and a solid 2-year warranty backs it up. The Simrad NSS9 evo3S is an excellent choice for those who need a reliable, high-performance chartplotter with extensive features for a variety of marine applications.

The Humminbird APEX 19 MEGA SI+ is a solid choice for anglers who want a large, detailed display and advanced sonar capabilities. It features a sharp 18.5-inch full HD screen (1920x1080), which makes reading charts and sonar images easy, with excellent clarity to spot fish and underwater structures. The touchscreen controls combined with keypad options offer flexible and intuitive operation, along with a user-friendly interface that allows customization to suit individual preferences.

GPS accuracy is reliable thanks to its internal GPS and Humminbird’s detailed basemap, covering over 10,000 lakes and coastal areas in the U.S., plus support for premium charts like LakeMaster and Navionics, giving great versatility for navigation and fishing. The sonar is a standout, using MEGA Side Imaging+ and Dual Spectrum CHIRP sonar that provide clear, wide views under and around the boat, helping anglers detect fish more easily. Connectivity is strong with Bluetooth, HDMI, dual Ethernet ports, and compatibility with other Humminbird and Minn Kota devices, making it good for building an integrated system.

The device is also durable enough for marine conditions, with a solid mounting system included. However, it is a heavier and bulkier unit at over 15 pounds, which might be a consideration for smaller boats. While the price and complexity might be more than casual users need, serious fishermen will appreciate the advanced features and powerful performance this chartplotter offers.
