10 Best Garmin Chartplotter 2025 in the United States

The Garmin ECHOMAP Ultra 122sv is a solid choice for anglers looking for a large, easy-to-use chartplotter and fish finder combo. Its 12-inch keyed-assist IPS touchscreen offers sharp, bright visuals with a resolution that makes reading maps and sonar images comfortable even in bright daylight. GPS accuracy is reliable, supporting detailed navigation with a preloaded worldwide basemap and compatibility with advanced BlueChart and Navionics maps, although these extras come at an additional cost. The included GT56UHD-TM transducer stands out by combining traditional CHIRP sonar with high-definition ClearVü and SideVü scanning sonars, providing clear underwater views with about 20% more range than older models.

Color palettes help distinguish fish and structures easily, and the unit supports advanced Panoptix sonars if you want to upgrade later. Connectivity is good, featuring Bluetooth for sharing waypoints and routes with other Garmin units, and wireless options add convenience. The user interface blends touchscreen with physical keys, which some users find helpful in tough conditions or for quick control. The Quickdraw Contours software is a valuable feature that allows you to create custom depth maps while fishing.

In terms of durability, the unit includes a quick-disconnect bail mount for flexible installation, although no specific waterproof rating is provided, so caution around water is recommended. This product is well-suited for serious hobbyist anglers who want detailed sonar views and reliable GPS navigation combined in one package, though it may be more feature-rich than casual users require and necessitates additional chart purchases to unlock its full capabilities.

The Garmin ECHOMAP Ultra 2 with a 12-inch screen offers a bright, sharp display (1280 x 800 resolution) that's easy to see and use even in bright sunlight. Its hybrid touch controls make navigation straightforward, balancing touchscreen ease with physical button reliability. For GPS accuracy, it supports multiple satellite systems (GPS, GLONASS, GALILEO, BEIDOU) and updates position at 10 times per second, which means your location on the water is pinpointed quickly and precisely.

Mapping comes preloaded with detailed Navionics+ charts covering North America, providing rich information for navigation and fishing spots. Connectivity is strong, with dual microSD slots for extra maps or data, two network ports for connecting other devices, and compatibility with NMEA 2000 systems, making it easy to integrate with your boat’s electronics. Sonar capabilities stand out thanks to the included LiveScope Plus bundle, providing real-time, clear imaging of underwater structures and fish with multiple CHIRP frequencies and ClearVu/SideVu scanning to cover a wide area around your boat.

The user interface is designed for ease, combining touchscreen and buttons, but those new to advanced chartplotters may face a learning curve given the many features. The unit is somewhat heavy at 14 pounds and fairly large, so ensure your boat’s mounting space can accommodate it. This chartplotter is ideal for serious anglers and boaters wanting detailed sonar and mapping combined with reliable navigation. It may be more than casual boaters need, but it delivers excellent performance for those focused on fishing and precise positioning on the water.

The Garmin GPSMAP 8616 is a solid choice for boaters who want a large, clear display and reliable navigation features. Its 16-inch HD IPS touchscreen offers vibrant visuals and good viewing angles, which makes reading charts and sonar data easier, even in bright daylight. The device includes detailed Garmin Navionics+ coastal and inland water charts for the U.S. and Canada, providing a wide range of mapping options for varied waters. GPS accuracy is strong, helping with precise location tracking on the water.

Connectivity is handled through Wi-Fi, allowing for updates and some wireless features, though it lacks some of the broader networking options found in higher-end models. It supports both traditional and scanning sonar, plus live sonar functions, useful for monitoring underwater conditions and fish activity more closely. The inclusion of a motion sensor adds convenience by automatically adjusting the display based on boat movement. Mounting is straightforward with panel mount options and a simple design.

Due to its size and weight—16 inches and 15 pounds—it requires a dedicated space on your boat, which could be limiting in smaller vessels. The user interface is intuitive thanks to the touchscreen and Grid 20 remote control, although there may be a learning curve for those new to chartplotters. This Garmin unit is well-suited for boaters seeking a large, feature-rich chartplotter with good sonar capabilities and reliable map coverage, but may be less ideal for those needing ultra-compact or highly rugged units.
