Elevate your maritime communication with the Vesper Cortex-H1 Handset Tethered. Engineered as the primary voice and calling interface for Cortex M1 or Cortex V1, this rugged handheld delivers crystal-clear VHF and DSC functionality at your fingertips, no matter where you are on deck.

The Cortex-H1 features a 4-inch multi-touch display protected by Gorilla Glass for maximum durability. Its glove- and salt-water–ready touchscreen is optically bonded to deliver exceptional wide-angle and sunlight viewability—even under the harshest mid-day glare. Navigate with a single hand using the innovative Click-Wheel and dedicated physical buttons for swift, intuitive control.

Designed for the demanding marine environment, the H1 combines VHF communications with AIS visibility and voiced alerts, giving you a unified cockpit on the move. Touch a vessel onscreen to initiate direct calling (DSC) and stay on top of alarms, vessel data, and remote monitoring from anywhere on the boat. It’s the perfect upgrade for Cortex M1 users looking to expand reach and situational awareness across multiple stations.
