Proven Simrad Interface
The A2004 builds upon the proven user interface and keypad layout of the Simrad AP70 and AP80 professional autopilot controllers, and delivers consistency with the latest generation of Simrad radar, sonar, and ECDIS displays.A large aluminium rotary control dial enables quick but precise steering adjustments, while dedicated keys offer instant access to steering modes, a custom-configurable Work mode, and automated turn patterns. All built-in controls are designed for ease of use with wet or gloved hands, in commercial settings such as fishing vessels and workboats. The A2004 also supports a wide range of Simrad autopilot remotes and steering levers.
Continuum Steering Technology
Every Simrad steering innovation builds upon a legacy encompassing over sixty years of autopilot development, which continues to this day. This legacy is exemplified by the Continuum algorithm: the software behind Simrad steering technology. Continuum steering distils years of research and on-water testing into a flexible software solution, capable of delivering reliable auto-steering performance tuned specifically to match a vessel’s control characteristics. With a comprehensive range of hardware and interface modules, Simrad autopilot solutions can be tailored to suit a wide range of commercial vessels and applications.
Optically Bonded 4.1-inch Color Display
To ensure optimal visibility in all conditions, the A2004’s colour LCD panel is optically bonded to its protective glass covering – eliminating the possibility of internal condensation. Transflective LCD technology makes use of reflected sunlight to brighten rather than obscure the screen, delivering superior day-time visibility and lower power consumption compared to traditional backlit displays. An ultra-wide 170 degree viewing angle means key autopilot information is clearly visible at a glance, from anywhere in sight of the display.
Thruster Integration & Rudder Feedback Support
The A2004 enables autopilot control of a single thruster via an optional AD80 or SD80 interface module. The thruster can be set to engage automatically below a user-defined speed threshold, and configured separately for normal and Work modes. The A2004 also supports specialized heavy-duty rudder feedback units designed for reliable operation aboard commercial vessels.
