Choosing a marine chartplotter for sonar navigation usually comes down to features and price, but this head-to-head also asks you to weigh readiness. The Garmin GPSMAP 440S is priced at $279.99, while the Simrad NSS7 EVO3 is listed at $394.94. Here's how to decide which one fits your boat and your plan.
Quick Verdict
For most boaters, the Garmin GPSMAP 440S is the better pick. It costs less and comes with the basics you need to get it on your dash. The Simrad NSS7 EVO3 has a bigger model name, but the item details point to a parts-only reality. Unless you have a specific need for a Simrad NSS7 EVO3 donor unit, the Garmin is the one to choose.

Where Each Product Wins
The Garmin wins for a straightforward chartplotter purchase: it's the lower-priced unit and it arrives with the basics. The Simrad wins only for a buyer who wants a Simrad NSS7 EVO3 chassis as a parts source. The 90-day warranty on the Simrad gives a little protection, but that's a niche use case.
Product Notes
Garmin GPSMAP 440S
The Garmin GPSMAP 440S is a straightforward GPS chartplotter for boaters who want a display ready to go. The package includes a suncover, mount, and power cord, so you can mount it and connect it without buying extra basics. It's the more affordable option in this comparison. The unit is listed as used. If you need a dedicated chartplotter, this Garmin gives you a clear path to navigation. The model focus is a GPS chartplotter, which is a different scope from the Simrad's all-in-one chartplotter, fishfinder, sonar, radar, and GPS name.
Simrad NSS7 EVO3
The Simrad NSS7 EVO3 gets attention because its name promises a lot: chartplotter, fishfinder, sonar, radar, and GPS in one head unit display. But the item description clearly states it's for parts or not working. The description mentions a cracked screen, possibly opened or loose screws, no power, and a nonresponsive touchscreen and buttons. Despite the higher price, this unit makes sense only if you're specifically sourcing a Simrad NSS7 EVO3 for parts or a repair project. The 90-day warranty listed in the item details is a small safety net, but the core reality is that this is not a functioning chartplotter.
Final Choice by Use Case
Choose the Garmin GPSMAP 440S if you want a chartplotter that costs less and comes with its accessories. Choose the Simrad NSS7 EVO3 only if you have a specific parts need for that model. For nearly every boater, the Garmin is the practical choice.
