Overview Garmin GPSMAP 376C Portable GPS Chartplotter
Garmin GPSMAP 376C Portable GPS Chartplotter is built for users who need marine navigation in a more portable format. The 3.8-inch color TFT screen and IPX7 water resistance make it suitable for boats that need a compact chartplotter with dedicated controls and the flexibility to move between setups.
A key strength of this model is its bundled GXM 30 smart antenna, which enables XM weather data such as animated NEXRAD, forecasts, wave conditions and current information within supported coverage. The unit also supports extensive waypoint, route and track storage, and it can be expanded with a separate Garmin black box sounder for depth capability.
Key Features
- Portable chartplotter design: The compact format makes the unit easier to deploy where a fixed helm installation is not required.
- Bundled weather capability: The included GXM 30 smart antenna supports XM weather content for better route awareness on the water.
- Clear 3.8-inch display: The 480 x 320 color TFT screen uses adjustable LED backlighting for readable operation in varying light.
- Strong navigation memory: The unit stores up to 3,000 waypoints, 50 reversible routes and a 10,000-point automatic track log.
- Rechargeable battery operation: A lithium-ion battery supports portable use for roughly 4 to 15 hours depending on backlight settings.
- Expandable sonar option: The chartplotter can be paired with a separate Garmin sounder to add depth data to the display.
Applications
- Portable marine navigation where a fixed helm chartplotter is not always practical.
- Boaters who want XM weather information bundled with their chartplotter setup.
- Backup navigation use or smaller vessels needing compact charting capability.
