Boat GPS Navigator 5in vs Garmin GPSMAP 1222: Which Marine Chartplotter Should You Buy?

A 5-inch marine GPS with AIS and dual charts for $336.52 vs a used 12-inch Garmin GPSMAP 1222 chartplotter for $1,300. Compare screens, navigation features, and condition to choose the right marine electronics sonar navigation setup.

Last updated Aug 17, 2026

Choosing marine electronics sonar navigation gear often starts with a basic trade-off: do you want a compact all-in-one navigator or a large chartplotter display? In this head-to-head, a new compact unit with AIS and dual charts sits well below a used Garmin chartplotter on list price; the two are separated by roughly $963. The decision comes down to how much display you need at the helm, whether you prefer new gear, and how much space you have.

Quick Verdict

Pick the Boat GPS Navigator 5in when you want a new, self-contained marine GPS with a small dash footprint and can work with a modest screen. Pick the Garmin GPSMAP 1222 when you want a large sunlight-readable chartplotter and are comfortable buying a used unit.

Where Each Product Wins

The Boat GPS Navigator wins for lower upfront cost, new condition, and tight helm spaces. It also brings AIS to the title and a dual chart system. The Garmin GPSMAP 1222 wins for readability and networking: the larger screen and higher resolution make charts easier to follow, and the unit connects into compatible Garmin marine systems.

Product Notes

Boat GPS Navigator 5in Marine GPS Navigator AIS TFT LCD Screen LED Backlight

Boat GPS Navigator 5in Marine GPS Navigator AIS TFT LCD Screen LED Backlight

This is the lower-priced route into marine navigation. Its compact TFT LCD uses a 480 x 272 resolution with LED backlight and a wide voltage design from DC 12-36V, so it is built around reliable operation. Positioning comes from a compass and GPS dual-mode system, while the built-in dual chart system with C-MAP MAP and XINUO MAP gives you two chart sets to switch between. It also supports multiple languages and six screen modes. Choose this unit if AIS in the title, a new unit, and a lower price matter more than a huge display. The trade-off is the small screen and lower resolution, so chart details will not be as glanceable as on the large Garmin plotter.

This is the display-first option. The large panel runs at 1280 x 800 and the listing describes it as sunlight-readable, which is a real plus at a bright helm. It has an internal GPS and GLONASS receiver, chart-plotting features, keypad controls, and network capability for compatible Garmin marine systems. The unit is sold as used and fully tested, with normal cosmetic wear, so you get a large plotter for a higher price than the compact model. Pick it when you want to read charts from a distance and plan to stay inside a Garmin-enabled network. The limitation is the used condition and the significantly higher price, which may be hard to justify if you mostly need basic waypoint navigation on a small boat.

Final Choice by Use Case

Choose the Boat GPS Navigator 5in if you want a new, compact navigator and a lower price. Choose the Garmin GPSMAP 1222 if you want a larger display and a Garmin-based network, and you are fine buying a fully tested used unit.
