The Garmin VHF 315 Marine Radio (Part Number: 010-02047-00) is a modular, 25-watt Class D Digital Selective Calling (DSC) marine communications system designed to deliver reliable, multi-station radio capabilities with a clean helm aesthetic. Featuring a blackbox design that installs out of sight, the unit operates entirely via the included GHS™ 11 wired handset and an active speaker, saving valuable console space while providing full operational control. It supports up to three GHS 11 handsets for seamless intercom communication across multiple helm stations or vessel locations. Equipped with NMEA 2000 and NMEA 0183 connectivity for easy integration with Garmin chartplotters and multifunction displays, the system includes built-in GPS capabilities (requiring an external antenna) to transmit accurate position data during emergency DSC distress alerts. Built to withstand harsh marine environments with an IPX7 waterproof rating, it is a robust and flexible communication hub for powerboats, yachts, and commercial vessels alike.
