Marine radios are communication devices specifically designed for use on boats and ships. They allow sailors and fishermen to communicate with each other and with shore stations, ensuring safety and coordination while at sea. These radios operate on specific frequencies, including the VHF (Very High Frequency) band, which is commonly used for marine communication. There are different types of marine radios, including fixed mount radios, which are installed on the vessel, and handheld radios, which are portable. Many marine radios also feature DSC (Digital Selective Calling), enabling users to send distress signals and communicate more effectively in emergencies.
