GHS 20 and GHS 20i full-function wireless remote handsets are compatible with Garmin’s VHF 200 and 300 series radios. They allow you to move about your boat and still have complete control of your radio. Each waterproof handset includes a backlit LCD display, soft keys, volume control, squelch and channel selection, a built-in speaker mike for use in loud environments, a DSC distress function, and 16/9 or 16+ channel selection. The handsets can also be coupled with a GWH 20 wireless hub, which can support up to three GHS 20/20i handsets onboard for communicating between handsets.
