The RS40-B includes a Class B AIS transceiver, which not only receives AIS targets but also transmits your boat's position to nearby AIS-equipped vessels. This helps other mariners to spot your boat in any conditions, day or night. The RS40-B is a Class B AIS VHF radio that not only receives AIS targets but also broadcasts your vessel's position to nearby AIS-equipped boats, enhancing safety and visibility in any conditions, day or night. Its built-in AIS receiver continuously monitors the location of surrounding vessels, allowing you to navigate busy harbors and congested waterways with confidence proactively. AIS data can be displayed directly on the radio s screen or integrated with compatible chartplotters and radar displays, providing a complete situational awareness system that helps reduce the risk of collisions and improves overall navigation safety. Designed for flexibility and convenience, the RS40-B features a removable fist microphone that can be connected to either the front or rear of the radio. Optional extension cables make it easy to separate the mic and radio for cleaner, more adaptable installations. For added mobility, you can pair the radio with the optional HS40 wireless handset, which duplicates the radio s display and controls, allowing you to use them anywhere on board. This will enable you to communicate and monitor AIS information from different locations on your boat without sacrificing access to critical functions, making the RS40-B a versatile, reliable, and user-friendly choice for modern mariners.
