Garmin ECHOMAP UHD2 73sv Without Transducer | 7in Touchscreen Chartplotter + Navionics+ U.S. Inland

Overview

The Garmin ECHOMAP UHD2 73sv Without Transducer packs a bright 7-inch touchscreen into a compact chartplotter designed for inland waters. The display remains readable in bright sunlit cockpit spaces, helping you interpret charts and sonar at a glance without sacrificing clarity or speed.

Built-in Navionics+ inland maps bring trusted cartography to your fingertips, offering detailed lake data and shoreline contours to support route planning, waypoint marking, and on-water decisions. You get a reliable base map without the need to swap cards, plus the option to add premium data as needed.

Key map and display benefits

• Coverage includes more than 18,000 lakes with up to 1-foot contour detail for precise inland planning
• Navionics+ data provides high-contrast depth and depth-shoal cues to help reading the water at a glance

Note that scanning sonar views like ClearVü and SideVü require a compatible transducer (sold separately). LiveScope sonar is also supported when paired with the appropriate transducer, expanding real-time scanning options on the water.

Connectivity and data sharing

• Built-in Wi‑Fi enables wireless sharing of sonar, waypoints, and routes with another ECHOMAP UHD2 unit, making multi-boat coordination smoother
• Seamless compatibility with the free ActiveCaptain app for OneChart access, software updates, and remote navigation planning on your smartphone

Performance and integration

Multi-band GPS enhances position accuracy in areas where signals are reflected or weak, helping you stay oriented in challenging waterways and under varying conditions.

Practical setup and use cases

This model can wire with select accessories via NMEA 2000 networks, allowing you to view autopilots, digital switching, and other connected devices on a single screen. It can also wirelessly connect to a Force trolling motor to create and follow routes, monitor battery life, and adjust motor settings from the chartplotter interface.

Because this unit ships without a transducer, you have the flexibility to choose a transducer that matches your fishing style and preferred sonar capabilities. When you add a transducer, you unlock enhanced scanning sonar and LiveScope features for more detailed water-column insight.

Real-world scenarios

• Inland lake trips with reliable contour data, easy waypoint management, and quick route adjustments
• River and reservoir exploration with clear map detail for safe navigation and efficient planning
