Simrad RS20S VHF Marine Radio: Reliable, User-Friendly Communication for Any Boat

The Simrad RS20S is a compact, Class D DSC-approved fixed-mount VHF radio designed for clear communication and enhanced safety on vessels of all sizes. With intuitive controls and essential features, it ensures easy operation in any conditions—perfect for recreational boaters and professionals alike.

Daylight-Visible Display and Simple Controls

Enjoy excellent readability with a high-contrast black-on-white screen for bright sunlight, plus an inverted white-on-black night mode for low-light conditions. A large rotary knob simplifies channel selection, while oversized buttons provide quick access to key functions. Dedicated Channel 16 buttons on both the main unit and fist microphone deliver instant emergency access.

Flexible Mounting Options

Install effortlessly with the included gimbal bracket for tabletop, overhead, or bulkhead mounting. For a sleek, integrated look matching Simrad glass-bridge displays, choose flush-mount installation with convenient front-access fixing.

Built-In Safety with Class D DSC and GPS

Stay connected and secure with full Digital Selective Calling (DSC) functionality. In an emergency, press the dedicated distress button to automatically transmit your boat's position via DSC—along with a traditional voice call on Channel 16—for faster rescue coordination. The integrated GPS receiver ensures accurate location data is sent even if other onboard electronics are off.

Global Channel Access and Smart Scanning

Designed for worldwide use, the RS20S supports all international VHF channels. Use tri-watch mode to monitor your current channel, Channel 16, and a customizable priority channel simultaneously (in the US, default includes calling Channel 9). Alternatively, scan all channels, selected favorites, or prioritize emergency channels to never miss critical safety messages.

Choose the Simrad RS20S for dependable, easy-to-use marine VHF communication that combines essential safety features, clear visibility, and straightforward installation in a compact package.
