Practical Sailor has selected the Icom COMMANDMICIII as a 2009 Editor's Choice product. IPX8 Submersible PLUS (1.5m depth for 30 minutes)
The IC-M504 withstands submersion in up to 1.5m depth of water for 30 minutes. It is equivalent to the IPX8 standard. All products are rigorously checked to pass the quality test at the factory.

M504 LCDICOM IC-M504 Marine VHF Radio has Large LCD with dot-matrix characters
The IC-M504 has a 168-charactor, full-dot matrix display that allows you to easily view a variety of information, such as GPS data, DSC emergency data, etc. The large buttons and knobs provide user friendly operation.

ICOM IC-M504 Marine VHF Radio is ITU Class D DSC
The IC-M504 has built-in class D DSC, which enables you to constantly monitor channel 70. This functionality provides users at sea with the peace of mind that they can call for help by pressing the “Distress” button if the need arises.

ICOM IC-M504 Marine VHF Radio features Position Request and Position Report
Over and above the DSC, your own and other ships’ position data can be exchanged with the position request or position report functions. The received position information can be transferred to external navigation equipment*. In addition, the polling (request/ reply) function checks whether a specific ship is within the communications range.
* External GPS receiver and navigation equipments which accept NMEA 0183 format are required.

ICOM IC-M504 Marine VHF Radio Has Superior receiver performance
The IC-M504 has excellent receive specifications of 80dB (typical) for intermodulation rejection, adjacent channel selectivity, and 0.22µV (typical) high sensitivity. The IC-M504’s superior receiver provides excellent resistance to intermodulation and allows you to catch a weak signal between strong stations.

ICOM IC-M504 Marine VHF Radio Provides Excellent audio output power
The extra large speaker is mounted into a well spaced housing, producing greater sound than the specified 4.5W output power. You can get clear and loud reception without requiring repetition of the message, even over the engine or other background noise.

25W hailer/RX speaker and auto foghorn
When connected to a hailer horn or external speaker on the deck or tower, you can make an announcement on-board from the microphone. The RX speaker function, “receiver-repeater”, allows you to monitor the received audio. Four foghorn patterns are also available for the automatic foghorn.

Rear panel microphone version*
With this version, the microphone connector is drawn from the rear panel and a 6.1m (20ft) microphone extension cable is supplied to allow you clean and neat panel installation.
