Garmin ECHOMAP UHD2 64sv 6" Fish Finder with Transducer

The Garmin ECHOMAP UHD2 64sv is one of the best 6-inch fish finders for anglers who need SideVü side imaging in a compact display format in Garmin's mainstream UHD2 lineup. It's a compact 6" touchscreen fishfinder and chartplotter delivering CHIRP traditional sonar, ClearVü down imaging, and SideVü side imaging, built-in GPS, and Garmin's mainstream feature set in a size that fits tight consoles, kayak mounts, jon boat dashes, and ice-fishing shelters. The included GT54UHD-TM transom-mount transducer is ready to install, no additional purchase required. This model ships with Navionics+ U.S. Coastal maps pre-loaded, making it inshore and nearshore saltwater anglers along the Atlantic, Gulf, and Pacific coasts.

Important, this unit does NOT support LiveScope, LiveScope Plus, or LiveScope XR. Garmin reserves live sonar support for the 7" and larger UHD2 models, a hardware tier limitation, not something that can be added later with an accessory. Panoptix live sonar (PS22, PS31) is also not supported. If live sonar is on your short list now or in the next year or two, step up to the 74sv tier. If live sonar isn't a priority and you need a compact, capable CHIRP + ClearVü + SideVü unit with GPS mapping, this is the right tier.

Who This Fish Finder Is For

The ECHOMAP UHD2 64sv is best for bass anglers, crappie fishermen, panfish anglers on small-to-mid size boats, and kayak tournament anglers who need real Garmin mainstream sonar and GPS in a compact form factor and don't need LiveScope or live sonar upgrade path. The 6" touchscreen fits in places a 7"+ unit won't, kayak mounts, jon boat dashes, tight helm panels, ice fishing shelters. The 6" tier gives you SideVü side imaging that the 5" tier does not have, a meaningful step up if you work shoreline structure or cover water.

Choose This If...

• You have limited console space, kayak, jon boat, small pontoon, or cramped helm.
• You don't need LiveScope or live forward-looking sonar, this tier does not support it. Step up to 7"+ UHD2 or Ultra 2 if live sonar matters.
• You want SideVü side imaging in a 6-inch format, the 6" UHD2 sv variants are the smallest Garmin units with SideVü.
• Inshore and nearshore saltwater anglers along the atlantic, gulf, and pacific coasts, this variant ships with Navionics+ U.S. Coastal maps pre-loaded. Inland anglers should pick 63sv. Canadian anglers should pick 65sv.
• Your budget is $800-$1,000, entry-to-mid mainstream tier with full GPS mapping.

Frequently Asked Questions

Is the ECHOMAP UHD2 64sv LiveScope compatible?

No. The 5" and 6" UHD2 models do not support LiveScope Plus, LiveScope XR, or LiveScope Original. This is a hardware tier limitation that cannot be bypassed with any accessory. If LiveScope matters to you, step up to the 7" or 9" UHD2 tier (73sv, 74sv, 75sv, 93sv, 94sv, 95sv) or the Ultra 2 tier.

Does it support Panoptix live sonar?

No. Panoptix PS22 and PS31 live sonar also require the 7"+ display tier. Same hardware limitation as LiveScope.

What's the difference between cv and sv?

"cv" means CHIRP + ClearVü (down imaging only). "sv" adds SideVü side imaging. This 64sv is an sv unit, includes SideVü.

Does the transducer come included?

Yes. This package includes the GT54UHD-TM transom-mount transducer. If you already own a GT-series transducer, consider the Chartplotter variant for savings.

What maps are included?

This unit ships with Navionics+ U.S. Coastal maps pre-loaded. Preloaded coverage includes U.S. coastal waters with marina, channel, and nearshore bathymetric detail. Inland anglers should pick 63sv. Canadian anglers should pick 65sv. All units accept LakeMaster, CoastMaster, and C-MAP cartography via microSD for expanded coverage.

Will this fit on my small boat?

The head unit is 7.3" W x 4.8" H x 2" D. It fits most 14-20 ft bass boats, aluminum boats, pontoons, and larger kayaks. It mounts with the included gimbal bracket or a RAM mount for kayaks. Requires 12V DC, a small 7Ah-12Ah battery is typical for kayak and jon boat installs. Most anglers install it themselves in 1-3 hours.

Can I use this for ice fishing?

Yes. The 5" and 6" ECHOMAP units are popular ice fishing choices due to their compact size and low power draw. For a complete ice-ready package, consider the Ice Fishing Bundle variant which includes the Dual Beam-IF transducer.
