The Simrad RS20S is a reliable, compact, and cost-effective fixed-mount VHF radio designed for cruisers and day boaters who require essential communication and safety features without the need for integrated AIS.

It balances ease of use with the robust performance expected from Simrad equipment, making it an ideal “workhorse” radio for steering consoles or helm stations where space is limited.

The RS20S features a compact chassis that fits into tight dashboards, while still providing a clear, high-contrast LCD screen. It is a Class D DSC (Digital Selective Calling) radio, which ensures you can send and receive distress alerts with the touch of a button. It is a streamlined, purpose-built radio that focuses on clear voice communication and reliable emergency signaling.

Key Features
