ICOM IC-M304 VHF Marine Mobile Transceiver

It's not just another marine radio. Fully featured compact marine VHF

The M-304's wide LCD shows large channel numbers and channel names of up to 10 characters. 4 levels of LCD backlighting are available.

Force5Audio™ The speaker's high sound pressure level delivers loud and clear reception.

Background noise is blown away! The microphone is tuned to pick up voice, while reducing ambient noise.

Built-in DSC capability The DSC (Digital Selective Calling) allows you to send a formatted distress message in an emergency. Position data is automatically exchanged between the two stations. DSC uses a unique ID (MMSI code) similar to a telephone number, allowing you to make contact with a specific boater or group of boaters in your area. A total of 100 address IDs can be stored with a 5-character name.

Submersible 1m depth for 30 minutes The installation of the IC-M304 is not limited to covered areas. Be assured, the IC-M304 can handle all types of wet! Equivalent to JIS Grade 7.

The IC-M304 comes in White, Grey or Black... Please be sure to state the color you want.
