The Simrad RS40 replaces the RS35 with significantly upgraded VHF radio functionality. It features a sleek design with wireless handset capability, removable fist microphone, Class D DSC functionality and built-in GPS. The Simrad RS40 also answers the call for increased situational awareness on the water. The built-in dual channel AIS receiver monitors the position of nearby AIS-equipped vessels to assist in collision avoidance in crowded waterways. The information is clearly visable on the screen or can be overlaid on top of a chart or radar through a compatible multifunction display.
