Feature: 1. Waterproof Walkie Talkie: The waterproof rating of the marine transceiver reaches IP67, which can be immersed in 1 meter deep water for 30 minutes. 2. Floating Function: After the marine 2 way radio falls into the water, it can float, and the light will automatically turn on to warn, so it will not sink or lose. 3. Good Sound Quality: The sound quality is full and clear, and the noise canceling technology effectively reduces ambient noise and improves the call experience. 4. Long Standby Time: Floating VHF radio uses a large capacity battery, the standby time can be up to 2 to 3 days, compact size, easy to carry, no burden for daily work. 5. Applicable Scene: Professional manufacturing, able to adapt to harsh environments, can be used in port logistics, ships, vehicle scheduling and other occasions.
