Garmin Echomap UHD vs Lowrance HDS Pro: Side-by-Side Comparison (2026)

You can argue all day about which fish finder is better. The honest answer is that the two best units in the high-end consumer market — the Garmin Echomap UHD2 (with LiveScope Plus) and the Lowrance HDS Pro (with ActiveTarget 2) — are both excellent. The right pick depends on what your boat already runs, what kind of fishing you do, and how you like to interact with a screen.

We ran both head-to-head for six months on Lake Mead, mounted side-by-side on the same console. Same boat, same days, same structure, same bait. Here's what actually changed our minds.

The basic specs

What we tested, and how

Both units ran on a 21-foot center console, on a Minn Kota Ulterra with a Quest motor, with each transducer mounted on a swappable jack-plate bracket so the readings were directly comparable. Six months of trips: predawn launches at Hemenway through Lake Mead from November through April, plus side trips to Lake Powell and Lake Havasu. Same operator, same software updates, same generations of chart cards. We didn't mix and match brands — both units were tested as the manufacturer intends them to be sold.

Round 1: Live sonar image quality

This is the round everyone wants the answer to. Honest answer: Garmin LiveScope Plus is still the benchmark. By a smaller margin than two years ago, but it's still the benchmark.

Specifically: LiveScope Plus produces marginally cleaner separation on suspended bait at distance — the difference between a 4-inch shad and a 14-inch striper at 60 feet is a touch more obvious than on ActiveTarget 2. ActiveTarget 2 has closed the gap in close-in structure work and is genuinely excellent in shallow water — better than the original ActiveTarget by a wide margin — but the long-range definition still goes to LiveScope.

The Forward, Down and Perspective modes on LiveScope Plus also feel slightly more polished as a UI than ActiveTarget's Forward, Down and Scout. Switching modes on Garmin is a single tap; Lowrance's implementation requires two.

Round winner: Garmin, narrowly.

Round 2: Side imaging

Lowrance's Active Imaging HD on the HDS Pro is excellent. So is Garmin's ClearVu / SideVu UHD on the Echomap UHD2. Run them back-to-back over the same offshore brushpile and the differences are remarkably small.

Where they do differ: Lowrance produces a slightly warmer, more contrasty image that's easier to read for less experienced users. Garmin's image is cleaner and more clinical — more information, presented with less editorial. Once you've put a season on either, the differences disappear.

Round winner: Tie.

Round 3: Charts and base maps

Garmin Navionics+ is the more familiar product to most North American anglers — bigger lake library, more frequent updates, slightly better contour density on the Western reservoirs. Lowrance C-MAP DISCOVER X is a stronger product than it was three years ago and looks particularly clean in canyon water — the contour shading on Lake Mead and Lake Powell on C-MAP is genuinely beautiful.

For Lake Mead specifically, both are accurate enough that you won't bottom out trusting either. For unmapped or sparsely mapped backcountry water, Navionics's Sonar Charts Live and C-MAP's Genesis Live are equivalent in 2026.

Round winner: Garmin, by a hair, on chart breadth. Lowrance, narrowly, on chart aesthetics.

Round 4: Self-mapping

Quickdraw Contours (Garmin) and Genesis Live (Lowrance) are both excellent. The two products are now essentially equivalent in functionality — drive over water, get a contour map. Both synchronize to the cloud, both let you share with your boat partners, both work fine.

The one functional difference: Garmin Quickdraw shows the contours live on screen as you generate them, with no manual cleanup required. Lowrance Genesis is a touch better at filtering noise (rougher water generates messier maps) but takes a little more configuration to look clean.

Round winner: Tie.

Round 5: User interface

The Garmin OS feels lighter and more responsive day-to-day. Menus are shallow, settings are where you'd expect them, and the touchscreen rarely mis-taps. The Lowrance HDS Pro OS is more configurable — you can build a custom screen layout that no Garmin will match — but the menus go three or four layers deep and there are settings you'll only find in the manual.

For first-time users: Garmin is a much faster learning curve. For power users coming from a previous Lowrance unit: the HDS Pro is the natural progression and you'll like it more than the Garmin.

Round winner: Garmin, on simplicity. Lowrance, on configurability.

Round 6: Networking and ecosystem

Lowrance wins this round outright. Up to six networked displays, ethernet backhaul, deep NMEA 2000 integration, Power-Pole integration, integration with most major trolling motors, the works. If you're building out a multi-screen tournament boat, the HDS Pro is the more future-proof choice.

Garmin's networking is fine but more limited at the Echomap level (you go up to the Garmin GPSMAP series for serious multi-screen work).

Round winner: Lowrance.

Round 7: Price

As tested, with live sonar in the box and a transducer install:

• Garmin Echomap UHD2 93sv + LiveScope Plus (LVS34): ≈ $2,800
• Lowrance HDS Pro 10 + ActiveTarget 2: ≈ $3,200

Garmin is around $400 cheaper for an arguably equivalent feature set. The HDS Pro's extra dollars are buying you a larger screen (10 inches vs 9), more configurability, and a deeper network. Whether that's worth $400 depends on the boat you're building.

Round winner: Garmin.
