Best Garmin ECHOMAP Chartplotters: 5 Compared

Choosing a Garmin ECHOMAP UHD2 chartplotter comes down to screen size, sonar view, mapping region, and whether the transducer is already in the box. Those differences matter more than small feature-list changes once the unit is mounted on your boat.

For most inland anglers, Garmin ECHOMAP UHD2 73sv is the strongest current all-around pick because it combines a 7-inch touchscreen with keyed assist, SideVü, ClearVü, traditional CHIRP, and the GT54UHD-TM transducer. For better value with simpler keyed controls, Garmin ECHOMAP UHD2 73cv includes the GT20-TM and Garmin Navionics+ U.S. Inland mapping.

These picks were checked against current manufacturer specifications, current retail availability, mapping bundles, sonar support, networking features, and safety records.

Garmin ECHOMAP UHD2 Chartplotters Compared

Garmin ECHOMAP UHD2 Chartplotters: Our Top Picks

1. Garmin ECHOMAP UHD2 53cv

Bottom line: The linked Garmin ECHOMAP UHD2 53cv is the older 010-02590-01 package with a 5-inch keyed display, GT20-TM transducer, and LakeVü g3 inland mapping. Current retailer listings mark this exact SKU as no longer available, so it is not one of our current recommendations.

• Screen: 5 inches, compact for small consoles.
• Controls: Keyed, easy to use with wet hands.
• Sonar: Traditional CHIRP + ClearVü, two below-boat views.
• Transducer: GT20-TM included, sonar hardware comes in the bundle.
• Mapping: LakeVü g3 U.S. inland, older built-in lake charts.

This older 53cv combines traditional CHIRP and ClearVü sonar with a small footprint. The GT20-TM transducer is part of the linked package, so the original bundle was designed as a ready-to-install sonar and chartplotter setup for inland use.

The important distinction is mapping generation. Part 010-02590-01 uses LakeVü g3 inland mapping. Garmin now sells a newer 53cv revision, part 010-02590-51, with Garmin Navionics+ U.S. Inland mapping.

2. Garmin ECHOMAP UHD2 54cv

Bottom line: Garmin ECHOMAP UHD2 54cv is the compact coastal choice. It gives you a 5-inch keyed display and Garmin Navionics+ U.S. coastal mapping, but the linked 010-02591-50 package does not include a transducer.

• Screen: 5 inches, compact for tight dashboards.
• Controls: Keyed, dependable without touch input.
• Sonar: Traditional CHIRP + ClearVü support, transducer required.
• Transducer: Not included, choose one for your installation.
• Mapping: Garmin Navionics+ U.S. coastal, built in.

The 54cv makes the most sense when coastal charts matter more than getting a transducer in the box. It supports Garmin traditional CHIRP and ClearVü sonar once you add a compatible transducer.

Its keyed interface is simple for a small helm, and built-in Wi-Fi works with ActiveCaptain for software and chart management. The trade-off is the extra transducer purchase and installation decision.

3. Garmin ECHOMAP UHD2 73cv

Bottom line: Garmin ECHOMAP UHD2 73cv is the value pick for inland anglers who want a larger 7-inch display without paying for touchscreen and SideVü hardware. The current 010-02594-51 bundle includes GT20-TM and Garmin Navionics+ U.S. Inland mapping.

• Screen: 7 inches, easier to read than 5-inch models.
• Controls: Keyed, straightforward in rough or wet conditions.
• Sonar: Traditional CHIRP + ClearVü, focused below the boat.
• Transducer: GT20-TM included, ready for supported sonar views.
• Mapping: Garmin Navionics+ U.S. inland, current built-in charts.

The 73cv gives you more chart and sonar area than the 5-inch models while keeping physical buttons. That extra screen space helps when you split mapping and sonar on one display.

Garmin pairs this current bundle with the GT20-TM transducer for traditional CHIRP and ClearVü. It does not add SideVü or the touchscreen interface found on the 73sv.

4. Garmin ECHOMAP UHD2 73sv

Bottom line: Garmin ECHOMAP UHD2 73sv is the best-balanced current pick in this group. Its 7-inch touchscreen with keyed assist, GT54UHD-TM transducer, SideVü, ClearVü, traditional CHIRP, and LiveScope compatibility give you more room to grow than the cv models.

• Screen: 7 inches, useful middle ground for split views.
• Controls: Touchscreen with keyed assist, flexible underway.
• Sonar: Traditional CHIRP + ClearVü + SideVü, three sonar views.
• Transducer: GT54UHD-TM included, supports bundled scanning sonar.
• Mapping: Garmin Navionics+ U.S. inland, built in.

The 73sv adds SideVü to show structure and targets beside the boat, not just below it. That is the main sonar upgrade over the 73cv. Touch control also makes chart panning and menu changes quicker, while keyed assist stays available when touch is less convenient.

It also supports LiveScope systems and NMEA 2000/NMEA 0183 networking. That makes it a better foundation if you expect to add live sonar, engine data, or other compatible marine electronics later.

5. Garmin ECHOMAP UHD2 93sv

Bottom line: Garmin ECHOMAP UHD2 93sv is the premium choice when screen area matters. The 9-inch touchscreen with keyed assist pairs with the GT56UHD-TM transducer for traditional CHIRP, ClearVü, and SideVü, while LiveScope and NMEA networking leave room for a larger electronics system.

• Screen: 9 inches, more room for maps and split views.
• Controls: Touchscreen with keyed assist, fast chart interaction.
• Sonar: Traditional CHIRP + ClearVü + SideVü, broad imaging options.
• Transducer: GT56UHD-TM included, higher-tier sv bundle.
• Mapping: Garmin Navionics+ U.S. inland, built in.

The 93sv keeps the same core sv-series approach as the 73sv but moves to a 9-inch 1024 x 600 display and the GT56UHD-TM bundle. The bigger panel is especially useful when you want chart and sonar panes visible at the same time.

Like the 73sv, it supports LiveScope and NMEA 2000/NMEA 0183 networking. Choose it when the larger display is worth the extra console space and budget; otherwise, the 73sv delivers the same broad system direction in a smaller format.

Garmin ECHOMAP UHD2 73sv vs 73cv: Is the Upgrade Worth It?

The 73cv focuses on value with a keyed 7-inch display, GT20-TM, traditional CHIRP, and ClearVü. The 73sv costs more but adds touchscreen control, SideVü, a GT54UHD-TM transducer, LiveScope compatibility, and broader networking.

• Side imaging: 73sv adds SideVü; 73cv is limited to traditional CHIRP and ClearVü.
• Controls: 73sv uses touchscreen with keyed assist; 73cv is keyed only.
• Expansion: 73sv supports LiveScope and NMEA 2000/NMEA 0183 networking.
• Value: 73cv keeps the 7-inch screen and included transducer with fewer advanced features.

Which Garmin ECHOMAP UHD2 Chartplotter Should You Buy?

• Compact coastal mapping: get the Garmin ECHOMAP UHD2 54cv.
• Best inland value: get the Garmin ECHOMAP UHD2 73cv.
• Best all-around 7-inch system: get the Garmin ECHOMAP UHD2 73sv.
• Largest display in this group: get the Garmin ECHOMAP UHD2 93sv.

How We Chose

• Exact bundle match: We checked model numbers, included transducers, mapping regions, and interface type against current manufacturer or major-retailer listings.
• Sonar capability: We separated cv models with traditional CHIRP and ClearVü from sv models that also add SideVü.
• Expansion: LiveScope and marine-network support mattered for buyers who plan to add electronics later.
• Current availability and safety: We checked current retail status and searched manufacturer and federal recall records before keeping products in the recommendation set.
• Owner feedback: We checked non-Amazon discussions for repeat patterns and did not turn isolated comments into claims.

Customer Preferences

For most buyers, the decision narrows to four questions: inland or coastal mapping, 5-inch versus 7- or 9-inch display space, whether a transducer is included, and whether you need SideVü or future LiveScope support. The cv models keep controls simpler, while the sv models give you more sonar and networking headroom.

Garmin ECHOMAP UHD2 Buying Guide

Choose the Screen Size Around Your Helm

A 5-inch unit saves dashboard space and works well when you mainly view one pane at a time. A 7-inch display gives maps and sonar more breathing room without requiring a large console. A 9-inch screen is better suited to frequent split-screen use. If you want the largest display here, Garmin ECHOMAP UHD2 93sv is the fit.

Decide Between Keyed Controls and Touchscreen With Keyed Assist

The 54cv and 73cv use physical keys. That keeps operation predictable when the boat is moving or your hands are wet. The 73sv and 93sv combine touchscreen control with keyed assist. If you want touch without giving up physical controls, Garmin ECHOMAP UHD2 73sv is the more compact sv choice.

Match Sonar Type to How You Fish

Traditional CHIRP shows fish arches and depth. ClearVü gives a scanning view below the boat. SideVü adds imaging to either side, which helps when you want to scan structure without driving directly over it. If SideVü matters, choose an sv model such as Garmin ECHOMAP UHD2 73sv or Garmin ECHOMAP UHD2 93sv.

Check What Is in the Box

A transducer changes both setup cost and capability. The 73cv includes GT20-TM, the 73sv includes GT54UHD-TM, and the 93sv includes GT56UHD-TM. The linked Garmin ECHOMAP UHD2 54cv does not include a transducer, so choose a compatible transducer before planning the installation.

Pick the Right Mapping Region

The current 73cv, 73sv, and 93sv bundles here use Garmin Navionics+ U.S. Inland mapping. The 54cv is the coastal option. Mapping is tied to the exact part number, so check the suffix before buying. For U.S. coastal use in a compact format, Garmin ECHOMAP UHD2 54cv is the direct match in this article.

Plan for LiveScope and Networking

If you expect to add LiveScope, start with an sv-series model. Garmin lists the 7- and 9-inch UHD2 sv units as LiveScope compatible and supports NMEA 2000 and NMEA 0183 networking. The Garmin ECHOMAP UHD2 73sv is a practical middle size; the Garmin ECHOMAP UHD2 93sv gives you more screen space.

Software Updates and microSD Cards

Garmin supports software updates through ActiveCaptain and through downloadable card-based updates. For Garmin’s current manual card-update package, the support instructions specify an 8–32 GB FAT32 microSD card. Garmin also notes that newer device software can support exFAT in some cases, so follow the instructions for your installed software and update method.

Mistakes to Avoid When Buying a Garmin ECHOMAP UHD2

• Buying by screen size alone: confirm cv versus sv sonar before ordering.
• Assuming every bundle has a transducer: check the exact part number and box contents.
• Mixing inland and coastal versions: verify the built-in mapping region.
• Planning LiveScope on a cv unit: choose a compatible sv model if live sonar is part of your upgrade path.
• Ignoring console clearance: measure the mounting area and cable clearance before choosing 7 or 9 inches.

FAQs

Do These Garmin ECHOMAP UHD2 Units Come Ready to Fish?

Some do, but not every bundle includes a transducer. The 73cv, 73sv, and 93sv links in this guide include GT20-TM, GT54UHD-TM, and GT56UHD-TM transducers respectively. The linked 54cv package does not include one. Always match the exact part number to the box contents before planning your installation.

What Is the Difference Between the 53cv and 54cv?

The model number mainly identifies the mapping region in these U.S. packages. The older linked 53cv uses LakeVü g3 inland mapping and includes GT20-TM, while the 54cv link uses Garmin Navionics+ U.S. coastal mapping and does not include a transducer. Current 53cv revisions use Garmin Navionics+ inland mapping.

What Is the Difference Between the 73cv and 73sv?

The 73cv uses keyed controls and supports traditional CHIRP plus ClearVü with the included GT20-TM transducer. The 73sv uses a touchscreen with keyed assist and adds SideVü with its included GT54UHD-TM. The 73sv also supports LiveScope and NMEA networking, so it offers a wider upgrade path.

Is the 93sv Better Than the 73sv?

The 93sv gives you a larger 9-inch display and comes with the GT56UHD-TM transducer, while the 73sv uses a 7-inch display and GT54UHD-TM. Both support traditional CHIRP, ClearVü, SideVü, LiveScope, and marine networking. Choose based on console space, screen-size preference, and budget rather than assuming bigger is necessary.

Can Garmin ECHOMAP UHD2 Work With LiveScope?

The 7- and 9-inch UHD2 sv models in this guide support Garmin LiveScope systems, including the 73sv and 93sv. The cv models focus on traditional CHIRP and ClearVü and are not the LiveScope path in this lineup. LiveScope transducers and related hardware are separate purchases unless a specific bundle says otherwise.

What microSD Card Should I Use for Updates?

For Garmin’s current downloadable card-update package, the support instructions call for an 8–32 GB microSD card formatted as FAT32. Garmin notes that exFAT may be supported on newer device software, and current manuals can allow larger cards for general device use. Follow the update instructions for your exact software version.

Do the 73sv and 93sv Support NMEA 2000?

Yes. Garmin lists NMEA 2000 and NMEA 0183 network support for the UHD2 7- and 9-inch sv series. That lets compatible systems share supported engine, navigation, autopilot, and other marine data. Network compatibility still depends on the connected equipment, cabling, and installation, so confirm each accessory before wiring the system.
