Garmin ECHOMAP Ultra 102sv w/GT56UHD-TM Transducer

Discover Unmatched Clarity on the Water

Imagine heading out at dawn, your boat slicing through calm waters, and spotting fish schools and hidden structures with crystal-clear precision before anyone else. The ECHOMAP Ultra 102sv paired with the GT56UHD-TM transducer turns that vision into reality for serious anglers chasing bass in shallow bays, walleye in deep lakes, or offshore species. This combo elevates your fishing game by blending advanced sonar imaging with intuitive charting, all on a vibrant 10-inch display that stays readable even under the harshest sun.

What sets it apart? It's not just about seeing fish—it's about understanding the underwater world. The GT56UHD-TM delivers Ultra High-Definition scanning that reveals baitfish balls suspended mid-water or subtle bottom contours that hold trophies, helping you position baits exactly where they need to be.

Superior Sonar That Reveals Every Detail

At the heart of this system is the GT56UHD-TM transducer, a powerhouse combining CHIRP traditional sonar for solid target separation with UHD ClearVü and SideVü scanning. ClearVü slices vertically through the water column like a knife, showing fish arches and wrecks in razor-sharp focus. SideVü extends your view up to 20% farther horizontally, painting wide swaths of the bottom to scout drop-offs and weed edges without repositioning.

Three frequency options let you dial in for shallow weedlines or probe depths over 800 feet. Vivid color palettes enhance contrast, so a thermocline or suspended crappie stands out against structure. Anglers report marking fish at 100 feet with details that mimic forward-facing sonar, making it a game-changer for jigging or trolling.

• CHIRP traditional: Excellent for tracking fast-moving targets.
• UHD scanning: 800 kHz for shallow precision, 455/260 kHz for range.
• Ready for LiveScope or Panoptix upgrades for real-time action.

Custom Mapping and Navigation Mastery

Preloaded worldwide basemaps get you started, but Quickdraw Contours lets you build your own 1-foot contour maps on the fly. Record sonar data as you explore, then refine spots for personal hot zones—perfect for tournament prep or sharing secret honey holes via the community (with your control).

Add coastal or lake charts for Auto Guidance paths that hug contours safely, calculating routes around shallows. Whether drifting a river mouth or running coastal inlets, quick waypoint marking and route planning keep you efficient and safe.

Seamless Connectivity for a Smarter Boat

Link up to compatible units to share sonar views, user data, and charts across your helm. NMEA 2000 integration pulls in engine stats, autopilot control, AIS targets, and even audio from Fusion systems—all viewable on one screen.

Wi-Fi pairs effortlessly with the ActiveCaptain app for software updates, smart alerts from your phone, and community map swaps. Control a compatible trolling motor directly from the plotter, following routes or holding position hands-free during drifts.

The quick-disconnect mount means you stow it securely at the dock or take it for multi-boat use, with cords staying put.

Built for Real Anglers, Every Trip

Keyed-assist touchscreen handles gloves and spray, while the solar-bright display fights glare. IPX7 waterproofing shrugs off downpours. Users love how it simplifies multi-species hunts: spot stripers schooling on bait with SideVü, then switch to CHIRP to drop jigs precisely.

Pro tip: Layer Quickdraw maps over enhanced charts to overlay your contours on pro-level detail, revealing ledges missed by stock data. For ice-out crappies or summer stripers, this setup consistently outperforms expectations.
