Overview

The GPSMAP 421 is a compact chartplotter that features an ultra-bright 4" (10.16 cm) QVGA color display along with an improved high-speed digital design for increased map drawing and panning speeds. It’s ready to go with a built-in, satellite-enhanced worldwide basemap and an easy-to-use interface designed to help you navigate the open waters with ease. The GPSMAP 421 also accepts BlueChart® g2 Vision® cards (sold separately) for added features and functionality such as high-resolution satellite imagery, 3-D views and Auto Guidance technology.

View Satellite-enhanced Worldwide Basemap

The GPSMAP 421 basemap contains worldwide satellite images in place of traditional maps. The GPSMAP 421 also comes standard with a high-sensitivity GPS receiver for superior satellite tracking and quicker acquisition times. In addition, the GPSMAP 421 can receive U.S. graphical weather data via optional GXM™ 51 satellite receiver/antenna. And with an SD™ card slot, it’s easy to add additional maps without connecting to a computer.

Add Extras with BlueChart g2 Vision

  • MarinerEye view and FishEye view provide you a 3-D perspective of map information, both above and below the waterline.
  • High-resolution satellite images and aerial photographs help you orient yourself in unfamiliar areas.
