The short answer
Pick Garmin if you want simple menus, sharp ClearVü and SideVü images and the strongest live sonar ecosystem in LiveScope. Pick Lowrance if you want the best chart value, C-MAP mapping out of the box and ActiveTarget 2 live sonar at a lower system cost. Both make excellent units; your network and budget decide it.

How we built this guide
This comparison is based on manufacturer spec sheets, published sonar and screen specs, owner reports on forums and long-term reviews from anglers. We did not run our own on-the-water tests, so we point out where owner experience differs from the marketing.
Which brand is easier to use?
Garmin is usually the easier brand to learn. Lowrance gives you more control, but there are more menus to dig through.
Garmin’s home screen uses big tiles and simple combos. Many owners say they were marking waypoints and reading SideVü on the first trip. Lowrance units let you build custom pages, change sonar colors and tweak almost everything. That is great if you like to tinker. It can feel busy if you just want to fish.
If someone else in your family will run the unit, Garmin’s simple layout is a real plus.
Whose sonar looks better?
On paper, both brands produce excellent pictures. Garmin’s ClearVü and SideVü are known for crisp, photo-like detail. Lowrance Active Imaging is known for clean structure images and good range.
The real difference often comes from the transducer that ships in the box. Garmin’s GT54 and GT56 transducers on ECHOMAP UHD2 sv models give you high-frequency scanning views. Lowrance’s Active Imaging 3-in-1 combines CHIRP, DownScan and SideScan in one housing. Owner reports suggest both are strong at bass and walleye depths. Pick based on features you want, not a screenshot on a box.
Garmin ECHOMAP UHD2 74sv
This 7-inch touchscreen bundle comes with a GT54 transducer and Garmin Navionics+ coastal mapping on the US model. It is a common pick for 16 to 19 foot boats. It also supports LiveScope if you add it later.

Lowrance Elite FS 7
The Elite FS supports Active Imaging, ActiveTarget 2 live sonar and C-MAP charts. It is a popular step up for anglers who want a networked unit without flagship cost. This listing is the head unit without transducer, so plan a transducer purchase.

Which brand has better maps?
Lowrance usually wins on maps out of the box at lower prices. Garmin wins on easy built-in contour mapping with Quickdraw.
Many Lowrance Eagle and Elite FS bundles ship with C-MAP charts. Garmin’s entry Striker line has no preloaded charts at all, only Quickdraw contours you record yourself. Step up to an ECHOMAP and you get Garmin Navionics+ on many models. If you fish big, unfamiliar lakes, built-in charts matter more than a slightly sharper sonar image.
What about live sonar?
Garmin LiveScope has the larger installed base and very clear target separation. Lowrance ActiveTarget 2 is often the lower-cost way to get forward-facing sonar.
LiveScope Plus works with ECHOMAP UHD2 (sv and cv models with networking), ECHOMAP Ultra 2 and GPSMAP displays. ActiveTarget 2 works with Elite FS and HDS PRO. Check that your exact display model is listed before you buy either. For a deeper live sonar comparison see our LiveScope vs ActiveTarget 2 guide.
Who it’s for / who should skip it
- Garmin is for: anglers who want simple menus, strong scanning sonar and the widest LiveScope support.
- Lowrance is for: anglers who want maps in the box, deep customization and lower live sonar costs.
- Skip brand loyalty if: you already own a trolling motor that talks to one brand. A Garmin Force Kraken pairs best with Garmin. A Lowrance Ghost pairs best with Lowrance.
What actually matters when buying
- Screen size: 7 inches is the practical minimum for split screens. 9 inches or more is ideal for live sonar.
- Transducer in the box: a cheap bundle without side imaging can cost more later.
- Networking: needed for live sonar, extra displays and trolling motor control.
- Charts: check what is preloaded for your region.
- Marketing noise: max depth numbers and “fish ID” icons matter far less than frequency and transducer quality.
Watch-outs
- Garmin Striker units have no chart maps. Owners sometimes find this out after install.
- Lowrance menus can be overwhelming. Plan an evening with the manual.
- Head-unit-only listings do not include a transducer. Double-check the box contents.
- Mixing brands means you lose trolling motor integration features like spot-lock from the screen.
Budget options from each brand
The Garmin Striker Vivid 5cv gives you CHIRP and ClearVü with a simple interface but no maps. The Lowrance Eagle 5 gives you a small screen and charts on many bundles.

Which should you choose?
- Choose Garmin if you want the easiest unit to learn and plan to add LiveScope.
- Choose Lowrance if you want charts and ActiveTarget 2 on a tighter budget.
- Choose the brand of your trolling motor if you want spot-lock and route control from the screen.
- Choose either if you only need sonar. Both entry lines are proven.
Common questions
Is Garmin or Lowrance more reliable?
Both brands have solid track records and good warranty support. Owner reports of problems usually involve cables, connectors and transducer mounting, not the brand itself. Buy from an authorized seller to keep the warranty valid.
Can I use a Garmin transducer on a Lowrance unit?
No. Transducer connectors and signals are brand-specific. Some third-party transducers are made for each brand, but you must buy the version made for your display.
Does Lowrance work with Navionics?
Lowrance units use C-MAP natively and have supported Navionics cards on many models. Since Garmin owns Navionics now, check current card support for your exact unit before buying.
Which brand is better for kayaks?
Both make compact units that suit kayaks. The Garmin Striker Vivid and the Lowrance Eagle lines are both popular. See our best kayak fish finders guide for specific picks.
Should I wait for new models?
Both brands refresh lines every few years. The current ECHOMAP UHD2 and Elite FS lines are fully supported, so buying now is reasonable.
