The Icom IC-M412 is a robust marine VHF transceiver designed for reliable communication in maritime environments. It features a compact design with an intuitive user interface, making it suitable for both seasoned mariners and newcomers. The device operates on all available marine channels, including the U.S., Canadian, and international channels, ensuring comprehensive coverage for various maritime needs. The IC-M412 delivers a substantial RF output power of 25 watts, providing extended communication range, while a 1-watt low power setting is available for short-range communication to conserve battery life.

The transceiver is equipped with an integrated Class D DSC (Digital Selective Calling) receiver, enhancing safety by enabling automated distress signal sending and position reporting. Its large LCD provides clear visibility of channel numbers and status information, even in bright sunlight, facilitated by its adjustable backlighting. The device is IPX7 waterproof rated, ensuring resilience against submersion in water up to a depth of one meter for 30 minutes, making it ideal for harsh marine conditions.

The IC-M412 incorporates AquaQuake, a feature that uses low-frequency sound waves to clear water from the speaker grill, ensuring uncompromised audio quality. Its dual/tri-watch function allows users to monitor multiple channels simultaneously, enhancing situational awareness and safety. The transceiver supports NMEA 0183 connectivity, enabling integration with other marine electronics for seamless data sharing. The Icom IC-M412 is powered by a 12V DC supply and designed to meet stringent marine standards, making it a dependable choice for both recreational and professional marine communication.
