It's large, bright 4” color display is easy to read at a distance and 170 degree viewing angle. Glass-bonded anti-glare lens prevents fogging and increases contrast.

For enhanced night visibility, you have a choice of red/black, green/black or the normal night mode color scheme along with a dimmer control.
An optional handheld wireless remote control is available; however, for the highest level of convenience, control the GHC 20 using quatix™, the world’s first marine GPS navigation watch featuring ANT® wireless technology.
