For bigger boats, an installed below deck autopilot is a must. It's always there, always ready to take control. The drive units are more powerful, don't take up cockpit space and the installation is in a protected location.
The Evolution pilots with their 9-axis solid state sensors give the best performance regardless of changes in sea state or wind strength. Evolution technology makes installation easier than ever. No calibration required - no more gyrating round in circles to get the pilot calibrated!
