When you're shopping for marine electronics sonar navigation, the first question isn't which transducer or frequency you want. It's whether the unit will actually turn on when you need it. That's the core difference between these two listings. On one side, the SIMRAD NSS7 EVO3 is a multifunction display that bundles chartplotting, fishfinding, sonar, radar, and GPS into a single head unit. On the other, the Garmin Fishfinder 160C is a dedicated echo sounder with a more modest feature set. The Simrad carries a higher listed price, but the Garmin is the one that's actually ready to run. Let's sort out which one belongs on your boat.
Quick verdict
If you want a working marine electronics sonar navigation unit right now, the Garmin Fishfinder 160C is the sensible choice. It's listed in new open-box condition, priced at $175.00, and ready to help you find fish. The SIMRAD NSS7 EVO3, despite its broader capabilities and a $394.94 listed price, is described as having a cracked screen, loose screws, and no power response. It's a repair project, not a plug-and-play display. Only consider the Simrad if you're comfortable troubleshooting electronics and need donor parts or a salvageable screen.
Price and condition at a glance
| Product | Listed Price | Condition | Price Bar |
|---|---|---|---|
| SIMRAD NSS7 EVO3 | $394.94 | For parts or not working | |
| Garmin Fishfinder 160C | $175.00 | New other (see details) |
The price gap is $219.94, and that difference buys you a working unit instead of a broken one. But the Simrad does offer a much wider range of functions in its intended role, so the lower price of the Garmin is not the whole story.
Where each unit wins
The SIMRAD NSS7 EVO3 wins on capability. Its product title alone lists chartplotter, fishfinder, sonar, radar, and GPS capabilities, making it a true all-in-one navigation hub for a boat. For a boater who values having a single head unit for multiple tasks, this is an attractive collection of features, even if this particular unit is not functioning.
The Garmin Fishfinder 160C wins on practicality. It's listed as new open box, comes with a lower price, and is designed specifically for echo sounding and fish finding. You can mount it and go, without worrying about screen repairs or touchscreen response. For the majority of anglers, that combination of readiness and price is hard to beat.
Product notes
SIMRAD NSS7 EVO3
The SIMRAD NSS7 EVO3 is a serious piece of marine electronics sonar navigation gear, at least on paper. The title confirms it's a chartplotter, fishfinder, sonar, radar, and GPS display, so it's meant to be the command center of a boat. The listed price of $394.94 is higher than the Garmin, but you're getting a much broader feature set. If you have the skills to repair a cracked screen and diagnose a unit that doesn't power on, and if the 90-day warranty gives you any breathing room, this could be a way to build a high-end setup on the cheap. The limitation is obvious: the description says the screen is cracked, screws may have been opened, it doesn't power on, and the touchscreen and buttons are nonresponsive. That's not a minor fix; it's a project. Unless you already know this EVO3 platform and can source parts, you're taking a big risk.
Garmin Fishfinder 160C
The Garmin Fishfinder 160C takes the opposite approach. It's a dedicated echo sounder sonar fish finder, listed at $175.00 in new open-box condition. The simpler design means fewer ways for things to go wrong, and because it's a Garmin product with a specific manufacturer part number, you can reasonably expect it to fulfill its stated fish-finding purpose. This is the unit to choose when you want to spend less money and spend more time on the water. The trade-off is that it doesn't include chartplotting, radar, or GPS, so if you need those features, you'll have to buy additional devices. For a focused fishing boat or a budget-minded upgrade, that's acceptable. The open-box status also means you might be missing some original packaging, but the condition note indicates it's new other, which usually means fully functional.
Final choice by use case
For most boaters, the Garmin Fishfinder 160C is the straightforward pick. It's a working sonar unit at a lower price, and it gets you on the water with daily reliability. The SIMRAD NSS7 EVO3 is a niche buy for someone who actively wants to repair a multifunction display and is prepared for the time and cost of sourcing parts. If you want marine electronics sonar navigation that works today, take the Garmin. If you're chasing a potential bargain and enjoy the challenge, the Simrad might be worth a closer look.
