Retevis RM21 Noise-Cancelling Floating Marine VHF Radio
Retevis RM21 is a powerful and reliable floating marine VHF radio designed to keep you connected on the water. Featuring advanced noise-cancelling technology, this radio gives you clear communication even in the noisiest environments. With a water-resistant design, you can be sure that your communication will always be secure and reliable. It also has a floating design, so if it happens to go overboard, it will float to the surface, making it easier to retrieve. It is the perfect tool for anyone who wants to stay safe and connected while out on the water.
NRC Noise Reduction
NRC noise reduction technology is beneficial to reduce the noise in the transmission process, and transmit clear sound on the noisy sea.
IP67 Waterproof Function
With IP67 waterproof function, the radio can be kept in 1 meter of water for 30 minutes without affecting the use.
Vibration Draining Function
Press and hold the button and CH+ button for 2 seconds at the same time to activate the vibration drainage function, which lasts for 10 seconds. The water on the surface of the speaker is effectively drained through the vibration drainage function, prolonging its service life.
Float & Flash Alarm
With the float and flash alarm functions, it is convenient for you to find the radio after accidentally falling into the water.
NOAA Weather Alert
The weather at sea is changeable. Through NOAA weather alerts, you can easily learn about the latest weather information and emergencies, and take effective measures to deal with and reduce losses.
