Marine radios are communication devices specifically designed for use on boats and ships. They allow mariners 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 and handheld models. Fixed-mount radios are installed on the vessel and often have more power and features, while handheld radios offer portability. Many marine radios also include features like GPS integration and DSC (Digital Selective Calling) for emergency situations.
