Marine VHF radios are essential for ships and vessels of all sizes. VHF radio is a type of communication device that has transit capabilities and can help in getting rescue services in case of sea trouble. As the name suggests, a marine VHF uses radio waves for communication, typically in the range of 156 to 174 MHz.
Most of the VHF units which are available in the market today can operate in various channels. VHF marine telephony is monitored by various elements, such as weather, the height of the antenna, and the model of radio.

There are some basic channels and frequencies that are a worldwide standard such as the 156.8 MHz channel which is the crisis channel. Some VHF radio units also offer some additional functionality, such as dual power modes and some devices that pre-announce weather and climate change.
When you are looking to buy a VHF radio unit, choose one that has a bright light and can be used to hear and talk clearly under any weather conditions. Other factors that you can consider before purchasing if it comes with a watertight cover and sealant and can be applied submersible without damaging the device.
A typical marine radio is built to a high standard, especially easy to operate, and able to face the often rough conditions at sea, such as moisture, dust, and vibration. The most important thing that you need to consider is if the device supports all standard channels in the country where you live.
