Raymarine Ray53 VHF Radio - Integrated GPS Receiver

The Raymarine Ray53 radio is small in size but big on features and performance. It is a full-function VHF marine radio with Class D Digital Selective Calling (DSC) and a built-in GPS receiver. Simply program your boat’s MMSI number into the Ray53 and immediately benefit from the enhanced calling and safety features of DSC.

Raymarine Ray53 Key Features

• Compact marine VHF with Digital Selective Calling
• Built-in GPS/GNSS receiver with a connection point for an optional external antenna
