ICOM IC-M100 is a VHF FM Marine Transceiver featuring an advanced RF front end circuit with helical resonators, MOSFETs and both crystal and ceramic filters for improved adjacent channel and intermodulation rejection. It's weatherproof and dust-tight, meaning that it can withstand harsh marine environments. It also has a newly designed display that uses a soft orange illumination for easy visibility when operating on bright days. ICOM IC-M100 comes with 16 user-programmable memory channels with a backup lithium battery, so you can easily store and recall your favorite channels. It also has 4 different channel scanning systems, so you can quickly find the channel you're looking for.
