MHS050-2 specifications

The Uniden MHS050-2 is a premium handheld marine VHF radio designed for boaters who require reliable communication while at sea. This radio stands out for its robust construction, user-friendly interface, and advanced features that cater to the diverse needs of mariners, whether they are recreational boaters or professionals.

One of the key features of the MHS050-2 is its waterproof design, rated to JIS7 standards. This means that the radio can withstand submersion in water up to one meter for 30 minutes, making it ideal for use in wet conditions typical of marine environments. The floating design adds an extra layer of security, ensuring that the radio remains buoyant if accidentally dropped overboard.

The MHS050-2 boasts a transmission power of 5 watts, allowing for clear communication over long distances. This is essential in emergencies or when coordinating with other vessels. It operates on VHF marine channels, which are specifically allocated for marine communication, to provide clear and uninterrupted signals.

One of its standout technologies is the built-in Digital Selective Calling (DSC). DSC allows users to send distress signals with their vessel’s GPS coordinates to nearby vessels and coast guard stations, dramatically enhancing safety while at sea. This feature can be a lifesaver in critical situations.

Another notable characteristic is the large, illuminated LCD screen, which ensures visibility in low-light conditions. The intuitive menu structure allows for easy navigation between channels and settings, making it accessible even for those who may not be tech-savvy. The unit also has a dual-watch feature that enables users to monitor two channels simultaneously, further improving situational awareness.

Additionally, the MHS050-2 includes an integrated emergency strobe light, adding another element of safety by providing visibility in emergencies. The rechargeable battery offers extended usage, with a built-in battery saver mode to conserve power during long trips.

Overall, the Uniden MHS050-2 marine VHF radio combines durability, safety, and innovative technology. Its user-oriented design and advanced functionalities make it a trustworthy choice for anyone looking to enhance their maritime communication and safety measures.
