Built-in 66 channel GPS receiver

66 Channel WAAS GPS receiver built into the face of the radio. Providing the flexibility of using the NMEA2000 data bus or the built-in GPS to provide highly accurate position data on the display of the radio.

NMEA2000 Compatible

Easy plug and play connectivity to the NMEA bus. A single plug in interface allows connectivity of GPS data, and DSC calling between compatible devices.

Second Station RAM4 compatibility

Now compatible with Standard Horizon’s latest second station microphone RAM4, model SSM-70. All functions on the main radio can now be controlled on the Second Station RAM4, this includes all radio functions, DSC functions, and intercom features between the radio and the Second Station.

E2O Easy to Operate Menu System

Redesigned with the operator in mind, the new Easy to Operate menu system is now more intuitive than ever. Access all the menu functions and settings with just a few simple steps. DSC calling and DSC programming has never been easier.

Ultra-Compact Easy Installation

Mounting a VHF radio has never been easier. The Explorer Series VHF’s have an ultra-thin, compact rear case, only 82 mm in depth or half the depth of comparable VHF radios on the market. The rear case design also gives flexibility when flush mounting the radio (requires optional MMB-97 bracket) in tight areas or bracket mounting the radio by taking up less dash space and allowing more mounting options.
