Garmin ECHOMAP Ultra 2 126sv Bundle w/GT56UHD-TM Transducer
Garmin ECHOMAP Ultra 2 126sv Bundle w/GT56UHD-TM Transducer — Product description
The Garmin ECHOMAP Ultra 2 126sv with GT56UHD-TM Transducer (MPN 010-02882-01, UPC 753759325572) is Garmin's 12-inch chartplotter / fishfinder bundle - includes the ECHOMAP Ultra 2 126sv display, the GT56UHD-TM transom-mount transducer (Garmin's top-tier transom transducer with CHIRP plus Ultra High-Definition ClearVu and SideVu), AND preloaded Garmin Navionics+ U.S. coastal and inland mapping. Ready-to-fish bundle for owners who want a complete chartplotter / fishfinder package without sourcing the transducer and charts separately. 12-inch sunlight-readable touchscreen display with WXGA IPS panel - the same display as the LiveScope Plus Bundle variant of this chartplotter (010-02882-10), with the same 1280 x 800 resolution and polarized-sunglasses friendly IPS technology. Touchscreen with Keyed Assist buttons for wet hands / gloves / rough water. The included GT56UHD-TM transducer is Garmin's top-tier transom-mount transducer - delivers traditional CHIRP sonar, CHIRP ClearVu down scanning at Ultra High-Definition frequencies, and CHIRP SideVu side scanning at Ultra High-Definition frequencies. UHD imaging means photographic-quality detail of bottom structure, brush piles, isolated rocks, fish, and bait - significantly more detailed than standard ClearVu and SideVu transducers. Preloaded Garmin Navionics+ U.S. coastal and inland mapping with Auto Guidance+ technology, 1-year subscription for daily map updates, depth range shading, and detailed Navionics chart features. Optional upgrade path to Garmin Navionics Vision+ premium mapping (sold separately) for high-resolution relief shading, satellite imagery, and additional fishing details. Full LiveScope live-scanning sonar support (transducers sold separately, requires GLS 10 black box) - if you want to add LiveScope later, the chartplotter is ready. Multi-band GPS for improved position accuracy in challenging conditions. Wirelessly networks one-to-one with another ECHOMAP Ultra 2 or UHD2 chartplotter for sharing traditional sonar, waypoints, and routes. Full-screen recording capability for capturing fish catches and trip moments to share. ActiveCaptain mobile app integration for smart notifications, OTA updates, and trip planning. Garmin Marine Network for radar, autopilot, and additional chartplotters as you expand the system.
It's Garmin's complete 12-inch chartplotter / fishfinder bundle from Garmin's ECHOMAP Ultra 2 series - includes the chartplotter, Garmin's top-tier transom-mount Ultra HD scanning transducer, and preloaded Garmin Navionics+ mapping. For owners who want a complete chartplotter / fishfinder package with the highest-resolution scanning sonar without sourcing components separately, this bundle is the right call.
What's in the bundle. Three components: (1) ECHOMAP Ultra 2 126sv chartplotter / fishfinder display - the 12-inch sunlight-readable touchscreen unit. (2) GT56UHD-TM transducer - Garmin's top-tier transom-mount transducer with CHIRP plus Ultra High-Definition ClearVu and SideVu scanning. (3) Preloaded Garmin Navionics+ U.S. coastal and inland mapping with 1-year subscription for daily updates. Everything needed for a complete install except the boat's power wiring, mounting hardware for the chartplotter at the helm, and optional NMEA 2000 network for engine data integration.
What 'UHD' (Ultra High-Definition) sonar actually delivers. Standard ClearVu and SideVu scanning sonars on entry-level Garmin transducers operate at 455 kHz and 800 kHz - good resolution but not breakthrough detail. Ultra High-Definition sonar on the GT56UHD-TM operates at frequencies up to 1.2 MHz - significantly higher frequency means significantly finer detail in the sonar return. Practical impact: brush piles look like individual branches instead of fuzzy blobs, isolated rocks show their actual shape vs vague returns, individual fish are clearly distinguishable from baitfish schools, and bottom composition (sand, mud, rock, vegetation) is visually distinguishable on the sonar image. For fishing applications where finding specific structure and individual fish matters, UHD sonar is meaningfully more capable than standard scanning sonars.
Why bundle vs head-unit-only. This bundle (010-02882-01) is one of several ECHOMAP Ultra 2 126sv variants Garmin sells. The bundle variants pair the chartplotter with specific transducers and chart cards for plug-and-play complete systems. The head-unit-only variant (no included transducer, no included charts) is for owners who already have a compatible transducer or want to source a specific transducer separately. This bundle's value vs separate purchases: the bundle pricing typically saves several hundred dollars vs buying the chartplotter, GT56UHD-TM transducer, and Garmin Navionics+ chart card separately, plus you get a single shipment with all matched components.
Same chartplotter as the LiveScope Plus bundle variant. The chartplotter portion of this bundle (the ECHOMAP Ultra 2 126sv display) is identical to the chartplotter in the LiveScope Plus Bundle variant (Garmin part 010-02882-10). Same 12-inch WXGA IPS touchscreen at 1280 x 800 pixels, same Multi-band GPS, same Garmin Marine Network and NMEA 2000 connectivity, same touchscreen with Keyed Assist controls, same LiveScope support (transducers sold separately), same wireless networking, same screen recording, same ActiveCaptain integration. The difference between bundles is just the transducer included: the LiveScope Plus Bundle includes the GLS 10 LiveScope black box plus LVS34 transducer (for live scanning sonar). This bundle includes the GT56UHD-TM (for UHD scanning sonar with no separate LiveScope). For owners who specifically want LiveScope, the LiveScope Plus Bundle is the right call. For owners who want UHD scanning without LiveScope, this bundle is more affordable and delivers excellent traditional + scanning sonar capability.
The 12-inch display. The display is a 12.1-inch diagonal WXGA IPS touchscreen at 1280 x 800 pixel resolution. IPS panel delivers wide viewing angles and sunlight readability through polarized sunglasses. Bright enough for direct-sun fishing on open helms. Touchscreen for fast smartphone-style operation, plus Keyed Assist buttons on the bezel for wet hands, fishing gloves, and rough water conditions. The 12-inch size is large enough for productive 4-pane split-screen views during serious fishing - chart, traditional sonar, ClearVu, and SideVu all readable at usable size from the helm seat.
The GT56UHD-TM transducer. The GT56UHD-TM is Garmin's premium transom-mount all-in-one transducer with three sonar capabilities in one unit: traditional CHIRP 2D sonar (the standard fish-arch view, 1 kW power), CHIRP ClearVu down scanning at Ultra High-Definition frequencies (photographic-quality detail directly below), and CHIRP SideVu side scanning at Ultra High-Definition frequencies (wide swath to each side with UHD detail). Transom-mount with included bracket and stainless hardware for boats with flat or near-flat transom configurations. Cable length sufficient for typical 25-35 ft boat transom-to-helm routing. Connect to the chartplotter's 12-pin sonar port for plug-and-play operation.
Preloaded Garmin Navionics+ mapping. You'll get a chartplotter that ships with Garmin Navionics+ U.S. coastal and inland mapping preloaded plus a 1-year subscription for daily map updates. Coverage: U.S. coastal waters (Atlantic, Gulf, Pacific) and U.S. inland mapping (lakes / rivers / reservoirs across all 50 states). Features: detailed depth contours, depth range shading (color-coded depth zones for safety), navigation aids (buoys, day markers, channels), shoreline detail, Auto Guidance+ for automated safe route planning around shallow water and obstacles. After the 1-year subscription expires, the maps still work but no longer receive automatic updates - subscription renewal is available through Garmin if you want continued updates.
LiveScope upgrade path - already supported. The chartplotter supports the full Garmin LiveScope live-scanning sonar lineup: LVS34 LiveScope Plus, LVS62 LiveScope XR, and the original LVS32. To add LiveScope to this bundle later, you'd add the GLS 10 sonar black box plus the LiveScope transducer (sold separately). The chartplotter is ready - no head unit upgrade needed when you add LiveScope. For owners who want LiveScope included in the initial purchase, consider the LiveScope Plus Bundle variant (010-02882-10) instead.
Wireless networking, screen recording, ActiveCaptain. The chartplotter wirelessly networks one-to-one with another ECHOMAP Ultra 2 or UHD2 unit for sharing traditional sonar, waypoints, and routes (LiveScope feed itself doesn't share wirelessly). Full-screen recording to SD card lets you capture fish catches and trip moments for sharing later. ActiveCaptain mobile app integration for smart notifications (call / text alerts on the chartplotter), over-the-air software updates, and trip planning from your phone pushed to the chartplotter.
Install considerations. You'll plan for 4-8 hours for an experienced installer. Tasks: mount the chartplotter at the helm (bail mount or flush mount), wire 12V power through a dedicated 5-10A breaker, mount the GT56UHD-TM transducer on the transom following Garmin's positioning guide (typically on the starboard side, below the cavitation plate, in the prop wash zone), route the transducer cable from transom to chartplotter helm location, insert the Garmin Navionics+ chart card if a separate card was provided (typically the mapping is preloaded internally), and run the initial setup wizard. For boats with existing NMEA 2000 networks, also connect to the network for engine data and additional sensor integration.

Frequently asked questions
What's the difference between this bundle and the LiveScope Plus Bundle?
Same chartplotter, different included transducer. This bundle (010-02882-01) includes the GT56UHD-TM transom-mount transducer for Ultra High-Definition CHIRP ClearVu and SideVu scanning sonar plus traditional CHIRP - excellent fishfinding capability without LiveScope. The LiveScope Plus Bundle (010-02882-10) includes the GLS 10 LiveScope black box plus LVS34 LiveScope Plus transducer for live-scanning sonar (real-time fish behavior and structure around the boat). For owners who specifically want LiveScope, the LiveScope Plus Bundle is the right choice. For owners who want top-tier transom-mount UHD scanning without LiveScope, this bundle is more affordable and delivers excellent sonar capability.
What does the GT56UHD-TM transducer give me?
The GT56UHD-TM is Garmin's top-tier transom-mount all-in-one transducer with three sonar capabilities in one unit: traditional CHIRP 2D sonar (1 kW power), CHIRP ClearVu down scanning at Ultra High-Definition frequencies (up to 1.2 MHz), and CHIRP SideVu side scanning at Ultra High-Definition frequencies (up to 1.2 MHz). UHD frequencies deliver significantly finer detail than standard ClearVu / SideVu transducers - brush piles show individual branches, isolated rocks show actual shape, individual fish are clearly distinguishable from baitfish schools. For serious fishing applications where finding specific structure and fish matters, UHD sonar is meaningfully more capable than standard scanning sonars.
Are charts really included?
Yes - Garmin Navionics+ U.S. coastal and inland mapping is preloaded on the chartplotter itself (not on a separate chart card). Plus a 1-year subscription for daily map updates is included. Coverage: U.S. coastal waters (Atlantic, Gulf, Pacific) and U.S. inland mapping (lakes / rivers / reservoirs across all 50 states). After the 1-year subscription expires, the maps still work but no longer receive automatic updates - subscription renewal is available through Garmin if you want continued updates. For owners cruising outside the U.S. or wanting Premium Vision+ mapping with relief shading and satellite imagery, additional chart cards are available for separate purchase.
Can I add LiveScope later?
Yes - the chartplotter supports the full Garmin LiveScope lineup (LVS34 LiveScope Plus, LVS62 LiveScope XR, LVS32 original). To add LiveScope: order the GLS 10 LiveScope sonar black box and a LiveScope transducer (LVS34 Plus typically), connect the GLS 10 to the chartplotter via Garmin Marine Network, and mount the LiveScope transducer on the trolling motor or other suitable mount. The chartplotter is already ready for LiveScope - no head unit upgrade needed when you add the capability later. For owners considering LiveScope from the start, the LiveScope Plus Bundle (010-02882-10) is more economical than this bundle plus separate LiveScope components.
What other transducers will work with it?
The chartplotter supports Garmin's full CHIRP / UHD transducer lineup via the 12-pin orange sonar connector: GT34 (basic CHIRP + ClearVu), GT41 (1 kW CHIRP + ClearVu / SideVu), GT51 (CHIRP + ClearVu / SideVu / Ultra HD), GT54UHD (Ultra HD scanning), GT56UHD (included transom variant in this bundle), GT56UHD-TR (the larger thru-hull variant), and more. Multiple transducers can be used if needed (e.g., a thru-hull CHIRP for deep water plus the GT56UHD-TM transom for shallow UHD imaging) by connecting to the appropriate sonar inputs.
Can I use it in saltwater?
Yes - the chartplotter and transducer are rated for both freshwater and saltwater use. Most appropriate for inshore saltwater applications where the GT56UHD-TM's UHD scanning shines (bay fishing, inshore stripers, snook, redfish in 5-100 ft depths). For offshore deep-water saltwater fishing, the UHD frequencies don't penetrate to typical offshore depths - the included CHIRP capability handles shallower offshore work, and you'd add a 2 kW thru-hull CHIRP transducer separately for deeper applications (over 1500 ft depth).
How is it networked?
The chartplotter supports two network protocols: (1) Garmin Marine Network (Ethernet-based) for high-bandwidth integration with Garmin radars (GMR series), additional Garmin chartplotters (multi-station boats), additional sonar modules (GCV / GSD series for advanced sonar applications), and Garmin GLS 10 for LiveScope integration. (2) NMEA 2000 for standard marine sensors (engine data via NMEA 2000, GPS, AIS, weather data, wind / depth / speed instruments). For boats with mixed-vendor electronics needing engine data integration, the NMEA 2000 support handles standard engine data feeds.
Wireless networking - what does it share?
The ECHOMAP Ultra 2 series wirelessly networks ONE-TO-ONE with a second ECHOMAP Ultra 2 or ECHOMAP UHD2 chartplotter for sharing: traditional CHIRP sonar feed, waypoints, and routes. Important caveat: the LiveScope feed itself doesn't share wirelessly - each Ultra 2 needs its own GLS 10 and LiveScope transducer to display LiveScope. The wireless one-to-one connection is plenty for waypoint and traditional sonar sharing between helm and bow stations on typical fishing boats. For more complex multi-chartplotter installations (3+ displays, multiple sonar sources to distribute), wired Garmin Marine Network is the more capable option.
How is it mounted?
Two mounting options included: (1) Bail mount - the U-bracket on top of the chassis lets you mount the chartplotter on a flat surface with the ability to tilt the display for optimal viewing angle. Most common mount for retrofits and where you want flexibility to adjust viewing angle. (2) Flush mount (optional flush mount kit, sometimes included or sometimes separate purchase) - for installations where you want the chartplotter integrated into the dash with the bezel flush with surrounding panels. Cleaner look but requires cutting the dash. Choose based on your specific install requirements and aesthetic preferences.
How much power does it use?
Approximately 1.5-2.5 amps at 12V during normal operation (about 20-30 watts), with peak draw higher during heavy sonar processing or at full backlight. Install with a dedicated 5-10 amp circuit breaker on a clean 12V circuit using 10 AWG marine-grade tinned cable for typical helm-to-distribution panel runs. Power draw is moderate - the chartplotter doesn't strain typical boat electrical systems.
What's the install like?
Plan for 4-8 hours for an experienced installer. Tasks: chartplotter mounting (bail or flush), 12V power wiring, GT56UHD-TM transducer transom mounting and cable routing, NMEA 2000 network connection if applicable, initial setup wizard, on-water testing. The transducer mounting is the most install-sensitive step - position correctly on the transom per Garmin's installation guide (starboard side, below cavitation plate, in prop wash, level when on plane) for best sonar performance. Bad transducer positioning causes turbulence and sonar dropout at speed.
What's the warranty?
Standard Garmin marine electronics 2-year limited warranty applies to the chartplotter, transducer, and bundle components. Garmin's warranty service in the U.S. is generally responsive and well-rated. Save the receipt and original packaging for warranty service.
