When you're on the water, other boats can present hazards for kayak fisherman. They can also be a lifeline. Cell phones are great when you find yourself in a hairy situation, but they don't always work. That's where the VHF radio comes in. It allows for on-the-water communication with other boats on the water, the Coast Guard, and you can also get weather information in case you don't notice the storm moving in on your location.
