Garmin ECHOMAP Ultra 2 166sv US and Coastal Canada GN+ with GT56UHD-TM Transducer Product Description
Imagine pinpointing your next big catch with crystal-clear images beneath your boat, all while navigating coastal waters with unmatched precision. The Garmin ECHOMAP Ultra 2 166sv, paired with the GT56UHD-TM transducer, transforms your fishing boat into a high-tech command center. Serious anglers swear by its massive 16-inch full HD touchscreen that delivers stunning clarity even under direct sunlight, making every sonar return and map detail pop. Whether you're chasing trophy bass in inland lakes or stalking stripers along the coast, this chartplotter's blend of advanced sonar, preloaded charts, and seamless connectivity keeps you ahead of the fish.
Unrivaled Display and Usability
The heart of this unit is its expansive 15.6-inch diagonal IPS display with 1920 x 1080 resolution, offering vivid colors and wide viewing angles perfect for crowded boats. Touchscreen controls are intuitive, backed by physical keys for glove-friendly operation during rough seas. Its IPX7 water rating shrugs off splashes and submersion, ensuring reliability on any adventure.
Ultra High-Definition Sonar That Reveals Everything
Thanks to the included GT56UHD-TM transducer, you'll get photo-like Ultra High-Definition ClearVü and SideVü scanning sonar at frequencies up to 1200 kHz. Combine that with CHIRP traditional sonar (covering low, medium, and high ranges), and separating fish from structure becomes effortless. High-contrast color palettes make targets stand out, while support for the entire LiveScope lineup lets you watch fish react in real-time—ideal for jigging or live-lining.
Superior Mapping and Navigation
Preloaded with Garmin Navionics+ charts for U.S. inland and coastal Canada, you'll have access to depth shading, daily updates via a one-year subscription, and detailed contours. Multi-band GPS (including Galileo, BeiDou, GLONASS) with 10 Hz refresh delivers pinpoint accuracy, even in canyons or under heavy tree cover. Garmin Quickdraw Contours lets you create personalized maps on the fly, and optional upgrades like Navionics Vision+ add satellite overlays and dynamic tides.
Smart Connectivity for the Modern Angler
Wireless networking shares user data like waypoints, routes, and sonar across multiple units—no cables needed. HDMI output mirrors your screen on a larger TV for crew viewing. Bluetooth enables hands-free voice commands for trolling motor adjustments or sonar scrolling. NMEA 2000/0183 compatibility integrates with engines, radars, and autopilots, while ActiveCaptain app support keeps software current and connects to a community of anglers.
