Navigating busy waters demands reliable communication, and the Simrad RS20S delivers just that with its rugged build and smart features tailored for everyday boaters. Whether you're out on a small RIB for a quick fishing trip or cruising a larger vessel, this fixed-mount VHF radio keeps you connected and safe. Its sleek, low-profile design blends seamlessly with modern glass bridge setups, ensuring your helm stays clutter-free and stylish.
What sets it apart? A built-in GPS receiver that pinpoints your location instantly, even if the rest of your electronics are off. Pair that with Class D DSC capabilities, and you've got a lifeline that automatically shares your position during emergencies—giving rescuers the edge they need to reach you fast.
From full international channel banks—no programming hassles—to tri-channel watch, every detail is crafted for real-world reliability on the water.
Getting the RS20S up and running is straightforward. The gimbal bracket supports table-top, overhead, or bulkhead mounting, while a front-mount option lets you flush-install without rear access—ideal for tight spaces. Its compact black design matches Simrad displays, maintaining that clean, professional look.
Power it with 12V DC (handles 10-16V swings), wire up NMEA connections if needed, and run the startup wizard: select your region, enter MMSI and call sign, pick GPS source, and set time offsets. You're ready to transmit in minutes.

Dedicated Channel 16 keys, found on both the radio and its fist microphone, offer instant access to the emergency channel. An 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: DSC, or "Digital Selective Calling", makes it easier to stay in touch with other boaters and enables you to broadcast your boat's location during an emergency. If you find yourself in trouble, the RS20’s dedicated "distress" button will initiate a DSC distress call that sends your boat's position to anyone within VHF range. Used together with a traditional radio distress call, this makes it easier for other boaters with DSC-capable radios to register your situation and come to your aid. An integrated GPS receiver means your position can be sent even if your boat's other electronics are powered down.
