Garmin ECHOMAP UHD2 74cv with GT20-TM Transducer

The Garmin ECHOMAP UHD2 74cv Chartplotter Fish Finder is a 7 in chartplotter and fish finder combo with a bright keyed display. It comes preloaded with BlueChart g3 US coastal charts with Navionics data. That makes it a good fit for bays, sounds and nearshore fishing.

Garmin CHIRP traditional sonar shows fish arches and bottom, and ClearVü scanning sonar gives near-photographic images of structure below the boat. High-contrast vivid color palettes make it easier to tell fish from cover. With the GT20-TM at 500 W, traditional CHIRP covers 50, 77, 83 and 200 kHz in low, medium and high bands and reads to about 1,900 ft. ClearVü runs at 260, 455, 800, 1,000 and 1,200 kHz and reads to about 750 ft. The unit also supports Garmin Navionics+ and Navionics Vision+ cartography as upgrades.

The 7 in screen has an 800 x 480 WVGA resolution, and the unit measures 9.1 x 5.6 x 2.6 in and weighs about 1.5 lb. It is IPX7 waterproof, runs on 9 to 18 V DC and draws about 1.0 A at 12 V. It stores 5,000 waypoints, 100 routes and 50,000 track points, with a microSD slot for cards up to 32 GB. The 5 Hz GPS receiver has WAAS support for fast, accurate position updates.

The GT20-TM transducer is included for CHIRP traditional and ClearVü scanning sonar, along with a power/data cable, tilt mount, flush mount and hardware. Built-in Wi-Fi connects to the free ActiveCaptain app for the OneChart feature, software updates and Garmin Quickdraw Community data. If you have another compatible 5 or 7 in ECHOMAP UHD2 aboard, the two can share sonar, waypoints and routes wirelessly. Other combos and units are in our fish finder units section.
