Product details

An Easy to Use Radio for Any Vessel
See clearly in bright daylight with a high contrast black-on-white display, and inverted white-on-black night mode. A rotary dial makes channel selection easy, while large buttons provide quick access to other key functions. Dedicated Channel 16 keys, found on both the radio and its fist microphone, offer instant access to the emergency channel. An included gimbal bracket enables simple table-top, overhead, or bulkhead installation. Flush-mount installation is also possible, with an easy mount-from-front solution, to match the low-profile style of our glass bridge displays and accessories.

Class D DSC Approved
An integrated Distress button allows quick DSC distress calling, which sends your vessel’s location to other DSC-equipped radios in range. DSC capabilities also enable direct calling to other DSC-equipped vessels from a Simrad multifunction display, including direct calls to vessels detected over AIS.

Easy Access to All International Channels
The RS20 is designed for global use and supports all international channels. With tri-channel watch, easily scan between the current channel, emergency channel 16, and another user-configurable priority channel (in the USA, scan between the current channel, emergency channel 16, and calling channel 9). Alternatively, scan through all available channels or just your selected favourites. Emergency channels can be given priority when scanning to reduce the chance of missing distress calls or other urgent safety messages.

Minimum product requirements

Requires a VHF antenna (sold separately). Some functions require a NMEA 2000® or NMEA 0183® connected GPS receiver. All DSC functions require an MMSI number issued by local authorities; charges may apply. Direct calling to AIS-equipped vessels requires an AIS receiver and a compatible Simrad multifunction display.
