    High Visibility Display

    See clearly in bright daylight with a high contrast black-on-white display. Night-time visibility has also been optimised, with an inverted white-on-black night mode to reduce light emission and preserve your night vision.

    Intuitive Controls

    A rotary channel dial facilitates quick channel selection, while large and amply spaced buttons provide quick access to all key functions. Dedicated Channel 16 keys enable instant access to the emergency channel, and are included on both the radio’s front panel and its four-button fist mic.

    Class D DSC Approved

    An integrated Distress button allows automated DSC distress calling. DSC capabilities also enable direct calling to other DSC-equipped vessels from a Simrad multifunction display, including direct calls to AIS targets (a compatible display and AIS receiver are required).

    Tri-Channel Watch Function

    Scan between the current channel, emergency channel 16, and another user-configurable priority channel (non US models). On US models, scan between the current channel and emergency channels 16 and 9.

    All International Channels

    The RS20 is designed for global use and supports all international channels including USA and Canada.

    My Channel Mode

    Select your favourite channels for quick and easy access. A long press on the channel dial enters My Channel Mode, where you can cycle through just your selected favourites using the rotary channel dial.

    Multiple Scan Modes

    Scan through all available channels or just your selected favourites. In either scan mode, emergency channels can optionally be given priority to reduce the chance of missing distress calls or other urgent safety messages.

    Easy Bracket or Flush-Mount Installation

    An included gimbal bracket enables table-top, overhead, or bulkhead installation. Flush-mount installation is also supported, with an easy mount-from-front solution, to match the low-profile style of Simrad Glass Bridge displays and accessories.
