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. In addition to voice communication, marine radios can also send distress signals and receive weather updates. Many modern marine radios come equipped with features like GPS integration and DSC (Digital Selective Calling), enhancing their functionality and making them essential tools for maritime safety and navigation.
