Two-way radios are communication devices that allow people to talk to each other over short distances without needing a phone network. They work by sending and receiving radio signals, making them useful for activities like hiking, camping, or working in large areas. Users can press a button to speak and release it to listen, which makes conversations quick and easy. These radios come in various sizes and styles, from handheld models to larger units used in vehicles. Many people use two-way radios for safety during outdoor adventures or in professions like construction, where clear communication is essential. They are often referred to as walkie-talkies or CB radios.
