Garmin BlueChart g2 WAAS XM Weather

The 430-series comes preloaded with coast-to-coast cartography for inland U.S. waters, of which over 5000 of these lakes and navigable waters include invaluable details such as extra resolution, depth contours, boat ramps, mile markers, hazards, marinas, campgrounds, area roads, and more. (Contiguous 48 states only.)

The powerful built-in analog sounder found in the 430s and 430sx can scan as deep as 900' (in dual beam mode) and features UltraScroll for high-speed screen updates. The 430s and 430sx also offer split-screen viewing of map and sounder data for easy, continuous reference.

The 430x and 430sx includes the GXM 31 Smart Antenna. With a subscription to XM Satellite Weather, the 430x and 430sx can provide continuously-delivered weather on the unit's high-resolution sunlight-readable display. Vital weather data, such as NEXRAD radar, forecasts, and current conditions is graphically displayed directly on the chart - so you can spend more time enjoying the water and less time worrying about the weather.

Enable offshore functionality of the GPSMAP 430-series with the addition of a BlueChart g2 Vision SD card

BlueChart g2 Vision cards provide:

  • High-resolution satellite imagery when overlaid on the chart, will provide the mariner with unparalleled situational awareness
  • Aerial reference photography provides "real world" photos of ports, harbors, marinas, waterways, navigation landmarks and other points of interest, offering the mariner another powerful tool for navigating unfamiliar waters
