Garmin ECHOMAP UHD 73sv Combo GPS/Fishfinder - US LakeVu BlueChart g3 w/GT56UHD-TM Product Description
Imagine spending less time searching for the perfect fishing spot and more time reeling in your catch. The Garmin ECHOMAP UHD 73sv transforms your boat into a high-tech command center, blending crystal-clear sonar imaging with intuitive GPS navigation tailored for U.S. inland waters. Paired with the GT56UHD-TM transducer, this 7-inch touchscreen powerhouse delivers Ultra High-Definition views that reveal fish, structure, and bottom details like never before.
Anglers rave about its vivid color palettes that make separating baitfish from trophy bass effortless, even in murky waters. Whether you're chasing walleye on a northern lake or bass in a southern reservoir, this combo unit equips you with the tools to outsmart the fish every trip.
Ultra High-Definition Sonar That Sees It All
The included GT56UHD-TM transducer brings three frequencies of scanning sonar to life: CHIRP traditional for deep-water precision, plus UHD ClearVü and SideVü for jaw-dropping side and down views. SideVü now reaches 20% farther, scanning wider areas without losing clarity. Spot schools hugging drop-offs or submerged timber from afar, then zoom in with high-contrast palettes that pop on the sunlight-readable display.
- CHIRP traditional sonar for reliable bottom tracking up to 2,300 feet in freshwater.
- ClearVü reveals nearly photographic down images of structure and fish arches.
- SideVü extends your scan range, perfect for covering vast flats or channels.
- Built-in features like sonar rewind, recording, and water temp graphs keep you in control.
Ready for upgrades? Pair it with Panoptix LiveScope for live-action views around your boat—fish that weren't there seconds ago suddenly appear in real time.
Navigate with Confidence Using LakeVü g3 Maps
Preloaded LakeVü g3 charts cover over 18,000 U.S. lakes with 1-foot contours and integrated Navionics data. No more guessing depths on unfamiliar waters—know exactly where to cast. Quickdraw Contours lets you map uncharted spots on the fly, creating custom 1-foot detail maps you can save or share via the Garmin Connect community.
From tournament pros to weekend warriors, users love how these maps blend high-res shading with shading relief for a 3D-like feel, helping you pinpoint hotspots faster.
Stay Connected On and Off the Water
Built-in Wi-Fi links to the ActiveCaptain app, turning your smartphone into a remote control for updates, notifications, and community data. Network multiple ECHOMAP UHD devices to share sonar, waypoints, and charts seamlessly. NMEA 2000 and 0183 compatibility integrates with autopilots, engines, AIS, VHF, and even the FORCE trolling motor for waypoint-following precision.
- One Garmin Marine Network port for easy expansion.
- Control trolling motors hands-free—dial in speed and direction from the plotter.

Frequently Asked Questions
What makes the UHD sonar on the ECHOMAP 73sv better than standard fishfinders?
UHD sonar uses advanced CHIRP frequencies across ClearVü, SideVü, and traditional beams for sharper images and 20% extended SideVü range, helping you distinguish fish from weeds effortlessly.
Does it work on saltwater as well as freshwater?
Optimized for U.S. inland lakes, it handles saltwater too with depths up to 1,100 ft at 77 kHz, though LakeVü g3 maps focus on freshwater coverage.
Can I customize maps with this unit?
Yes, Quickdraw Contours creates 1-foot custom maps in real time, which you can keep private or share through the Garmin Connect app community.
Is it compatible with other Garmin devices?
Absolutely—network with other ECHOMAP UHD models, connect via NMEA 2000/0183 to engines, AIS, and control FORCE trolling motors directly.
How does ActiveCaptain enhance the experience?
The app provides Wi-Fi software updates, smart notifications, OneChart access, and Quickdraw data sharing, managing your setup from your phone.
What's the maximum depth capability?
Up to 2,300 ft in freshwater at 77 kHz; performance varies by conditions like bottom type and water clarity.
Can I mount it flush on my console?
Yes, includes both quick-release bail and flush mount options for a clean, customizable install.
Pro Angler Tips for Maximum Performance
Adjust your color palette based on water clarity—vivid greens for shallow weeds, blues for deep structure. Troll at varying speeds to test SideVü range, and always calibrate sonar in known depths for accuracy. Pairing with LiveScope elevates it to pro-level scouting, turning casual outings into limit-filling days.
