Quick Verdict
When you're planning a boat's marine electronics sonar navigation, the first big decision is whether you want a single unit that handles both navigating and fishfinding or a dedicated echo sounder that keeps the sonar job straightforward. Garmin offers two different approaches here: the GPSMAP 541s arrives as a bundle with a display and combines navigating with fishfinding, while the Fishfinder 160C is a standalone echo sounder with a different feature mix.
If navigating and fishfinding in one unit are your priorities, the GPSMAP 541s bundle is the stronger fit. If you want a simple sonar unit and already handle navigating separately, the Fishfinder 160C is the more direct choice.

Where Each Product Wins
The GPSMAP 541s bundle wins when you want the combined experience. It is described as waterproof, and its bundle format gives you more to work with from the start. The main limitation is its used condition.
The Fishfinder 160C wins when your priority is a focused fish finder. It's listed in new-other (open-box) condition, a state that may appeal if you want an unused unit. The trade-off is that its listing centers on sonar; the GPS navigation function of the GPSMAP 541s bundle would have to come from a separate device.
Both units share the Garmin brand, so the decision stays within the same marine electronics family.
Product Notes
Garmin GPSMAP 541s 5in Marine GPS Chartplotter Fishfinder Gray BUNDLE
The Garmin GPSMAP 541s bundle combines a 5-inch marine display with chart and sonar capability, making it a one-device answer for marine electronics sonar navigation when you want to see charts and fish returns on the same screen. It's the more feature-dense option of the pair, and it carries the Garmin GPSMAP 541s name that signals a unit from the GPSMAP family. Choose it if you prefer a single unit that handles charting and fishfinding together. The trade-off is that no charger is included in the bundle, so you'll need to supply one before you rely on it. That small extra step is worth factoring into your planning. For shoppers who want a 5-inch screen and integrated chart and sonar tools, this bundle makes the case.
Garmin Fishfinder 160C Marine Boat Echo Sounder Sonar Fish Finder
If sonar is all you need, the Garmin Fishfinder 160C makes a straightforward case. It's a dedicated echo sounder that keeps its job simple, and it's positioned as a fish finder in its product name. Pick it when your boat already has a GPS unit and you only need a fish finder for the water ahead. It gives you Garmin sonar without the extra layers of a combo unit. Its limitation is scope: the listing focuses on sonar, so the all-in-one chart-and-sonar picture is left to the other unit. The 160C is the simpler way into Garmin sonar when the GPS side of a combo isn't required.
Final Choice by Use Case
Choose the Garmin GPSMAP 541s bundle when you want an integrated chartplotter and fishfinder and the bundle format appeals to you. Choose the Garmin Fishfinder 160C when you want a dedicated echo sounder, already have a separate navigation setup, and prefer the lower-priced side of the $74.99 gap. Either way, you're choosing between an all-in-one bundle and a dedicated sonar unit, so your existing boat setup is the tiebreaker.
