Perfect for your ocean-faring powerboat or sailboat, the Reactor™ 40 Hydraulic Corepack with SmartPump v2 is the most responsive boat autopilot system Garmin® has ever offered. At one time, this setup was only offered to commercial fisherman. Now, this advanced marine technology, when paired with a compatible Garmin chart plotter (not included), will take you from point A to B with minimal heading error, course deviation, rudder movement, and power consumption. This incredible system actually reacts to sea conditions. Even when your boat is pitching and rolling, you can be confident that the Reactor 40 is holding a steady course. Like most autopilots, the Reactor 40 requires commissioning and calibration. Unlike most autopilots, this one's start-up process is fast and as easy as possible. This system can perform a variety of preprogrammed trolling and search procedures, and with a Garmin chart plotter and BlueChart g2 Vision charts (not included), you'll enjoy extra features like, Auto Guidance, which will auto-steer GPS paths. Patented Shadow Drive technology ensures that you will always be in control, even when the autopilot is engaged. Shadow Drive automatically disengages the autopilot if the helm is turned, which allows you to manually turn the boat. Once you're back on a steady course, the autopilot automatically re-engages. The experts at Garmin has also included the SmartPump v2. Aptly named the SmartPump v2 fits almost all hydraulic steered boating applications, plus, you get complete control in a smaller size with better thermal performance, higher reliability, and lower power consumption. Its connections are even color coded, so it's even easier to install. The SmartPump v2 combined with the Reactor 40 automatically adjust the maximum flow rate for a particular boat from 0 to 2.4 liters per minute. Thanks to Intelligent Rudder Rate Technology (IRRT), the rudder rate is automatically slowed down when your vessel is travelling at higher speeds, and it automatically speeds up at slower speeds. This ensures optimal performance and safety in all kinds of conditions. The brushless motor drive eliminates the risk of rudder "hard over" due to hardware or software failures. Engineered to take on the harsh saltwater conditions, the SmartPump v2 features corrosion-resistant components along with anodized aluminum and nickel-plated steel parts. The Garmin Reactor 40 Hydraulic Corepack with SmartPump v2 includes: GHC 20, SmartPump v2, Reactor 40 Course Computer Unit, electronic control unit power cable, interconnect cable, Shadow Drive, buzzer, NMEA 2000® drop cables, NMEA 2000 power cables, NMEA 2000 T-connectors, male and female terminators, and documentation.
