Advanced Autopilot Control for Commercial Vessels

The Simrad A2004 System Kit with HS75 is a high-performance autopilot system designed to meet the demanding needs of professional mariners. Engineered for reliability and ease of use, this system delivers precision steering through Simrad’s Continuum steering technology, ensuring smooth and accurate navigation in challenging marine conditions. The system features an intuitive interface with a large rotary control dial for precise adjustments and an optically bonded color display for enhanced visibility in all lighting conditions.

Ideal for non-IMO professional vessels, the A2004 system supports a wide range of steering configurations, including reversible pumps and non-isolated solenoid valve controls. It also offers optional thruster integration for improved maneuverability at lower speeds.

High-Visibility Display for Optimal Readability

The A2004 features a 4.1-inch optically bonded color LCD with a 170° viewing angle, ensuring clear visibility from multiple positions on the vessel. Its transflective LCD technology enhances screen brightness using reflected sunlight, making it easily readable during the day while reducing power consumption.

Seamless Steering Control with Simrad's Proven Interface

Building on the legacy of the Simrad AP70 and AP80 professional autopilot controllers, the A2004 features an ergonomic keypad layout with dedicated buttons for instant access to different steering modes, including a configurable Work mode. The heavy-duty rotary control dial ensures quick yet precise steering adjustments, while the No Drift mode helps maintain a steady course against wind and tide.

Integrated Thruster and Rudder Feedback Support

The A2004 system supports a single thruster control via the optional AD80 or SD80 interface module, allowing the thruster to engage automatically below a user-defined speed. Additionally, it includes compatibility with heavy-duty rudder feedback units for enhanced performance on commercial vessels.

Certified Connectivity and Installation Flexibility

The system is NMEA 2000® certified, ensuring seamless integration with other onboard navigation and steering systems. It also offers flush or bracket mounting options, providing flexibility for different vessel setups.
