Choosing a used chartplotter for marine electronics sonar navigation usually comes down to a trade-off between price and readiness. The Garmin GPSMAP 1222 and the Simrad NSS7 EVO2 are two very different entries in that space, with a price gap of more than $1,000. The Garmin is a fully functional 12-inch chartplotter with internal GPS/GLONASS, while the Simrad is a for-parts unit. Here's how to decide between them.
Quick Verdict
If you need a chartplotter that can go straight onto your boat, the Garmin GPSMAP 1222 is the clear pick. It's a ready-to-run unit with a large, sunlight-readable display and a full set of navigation tools. The Simrad NSS7 EVO2 is far less expensive, but because its screen isn't usable, it only makes sense as a parts source or a repair project.
Comparison
| Product | Listed Price | Condition | Key Detail | Price Bar |
|---|---|---|---|---|
| Garmin GPSMAP 1222 | $1,300.00 | Used, fully tested and functional | 12-inch display, internal GPS/GLONASS, network capable | |
| Simrad NSS7 EVO2 | $219.99 | Used, for parts | Screen not usable |
The table highlights the core difference: the Garmin is a functional unit with a large display and network capability, while the Simrad is a parts candidate. Your choice really comes down to whether you need to be on the water this season or you're working on a repair bench.
Where Each Product Wins
Garmin GPSMAP 1222 wins if you want a ready-to-run unit. It's the only one of these two that can actually guide you on the water today, with a large display and easy keypad controls. The Garmin also includes a 1-year manufacturer warranty, giving you peace of mind on a used purchase.
Simrad NSS7 EVO2 wins if you're shopping for a parts donor or a repair challenge. It still powers on and the buttons respond, which is useful when testing other components in a compatible system. If you can source a replacement display or need internal components, the low price makes it a cheap way to get Simrad-specific parts.
Product Notes
Garmin GPSMAP 1222
The Garmin GPSMAP 1222 is a used, fully tested and functional chartplotter that shows normal cosmetic wear from prior use. The reason to choose it is that it's ready to mount on a boat and start navigating right away, with intuitive keypad controls that make it easy to operate on the water. The clear 1280 x 800 resolution is a plus for reading charts in daylight, and the unit is ideal for fishing boats, center consoles, and offshore vessels. It also includes a 1-year manufacturer warranty, so you have some protection after the sale. The main limitation is that you're paying the higher price for that readiness, and the used condition means the case and bezel won't look new. If you need a display that just works and you can accept some scuffs, this is the one to put on the shortlist.
Simrad NSS7 EVO2
The Simrad NSS7 EVO2 is a for-parts unit that turns on and responds to button presses, but it's not meant for everyday navigation. The reason to choose it is the very low investment entry into the NSS7 Evo2 family. If you already own a compatible Simrad system and need a donor for internal parts, or if you're willing to try replacing the screen, this could save you a lot compared to buying new components. The limitation is that it's sold as-is with no warranty and no returns, so you're accepting the risk that the unit may not be fixable. It's a true parts-only purchase, not a working chartplotter.
Final Choice by Use Case
- Choose the Garmin GPSMAP 1222 if you need a working chartplotter for fishing, cruising, or offshore navigation and want a display you can use immediately.
- Choose the Simrad NSS7 EVO2 only if you're repairing another unit or need Simrad parts, and you're comfortable getting no returns and no warranty.
Either way, your decision should be driven by whether you need a working chartplotter today or a box of parts for a project.
