Cobra does it again! The Cobra MR F80B has a range of useful features never seen before in a VHF radio. Rewind-Say-Again is a Cobra exclusive feature that uses a digital voice recorder to play back the last 20 seconds of audio. This unit has Class-D DSC functionality and provides improved performance for DSC calling. A commercial quality receiver with Local-Distance key allows you to desensitize the radio in high traffic areas. This allows for full sensitivity and maximum range when on the open water and in remote areas. A rotary channel changing knob is included for easy and fast working channel selection. Two channel Preset Keys, on the front under the LCD, allow you to easily preset your favorite working channel, and the large Dot Matrix Area LCD makes DSC calling simple and improves visibility for everyday use. The CobraMarine® Series GPS Chartplotters or any GPS with an NMEA 0183 output will provide GPS position. In addition, the position of polled vessels or vessels in distress will be displayed on CobraMarine Series GPS Chartplotters when properly connected to an MR F80B.
