The most compact and responsive autopilot system ever, ideal for small and medium-sized boats(1), reduced deviation and course errors, rudder movement with less power consumption. Easy to install and very simple to calibrate. Integrates seamlessly with the Garmin Marine system, also implementing the useful Auto Guidance 3.0 (2) function for automatic course calculation (requires BlueChart® g3 Vision® HD cartography). 9-axis solid-state AHRS technology The advanced 9-axis solid-state AHRS technology makes the system easy to install and super simple to calibrate, thereby minimizing errors in heading, deviation from courses, rudder movements and power consumption, allowing those on board to navigate more comfortably. Control the autopilot directly from the chartplotter: Fully interfaced via NMEA 2000 network, the new Reactor 40 autopilot can be controlled from the display of compatible Garmin Marine chartplotters. You can thus enjoy advanced features such as, for example, the new Auto Guidance 3.0(2 for automatic calculation of the best course and fast, simple and reliable navigation. Garmin Shadow DriveTM Using the unique Garmin Shadow Drive feature, the autopilot can be momentarily disabled when intervening on the helm, leaving the user free to maintain control of the vessel should the situation call for a quick maneuver or emergency procedure. The autopilot is then automatically reactivated when a stable course is maintained. Connection to networked devices: The Compact Reactor 40 autopilot can be activated directly from the chartplotter display Garmin compatible(1) or from 3 GHC control units. GHC communicates with the autopilot system via the NMEA 2000® network, allowing easy sharing of autopilot heading data with other devices. This enables MARPA and map overlay when the device is connected to a radar and chartplotter Garmin. An optional handheld wireless remote control is also available. Compatible with the following Garmin Marine devices: echoMAPTM CHIRP 52/72/92 series; ECHOMAP Plus 62/72/92 series; GPSMAP® 7400/8000/8400/8600 and 722/922/1022/1222 series.
