For RT55, we have the featured functions like IP67 and float, Vibration Water Draining Function.
As a marine radio, waterproof function is very important, when your radio dropping into the water, you can pick it up and continue to use. With a vibration function, when the body of the radio has a lot of seawater. It will penetrate into the inside of the radio, then the life of the radio is shorter. The vibration function can help your radio get rid of the seawater.
