Introduction
The external GyroPlus yaw sensor is an option to fit on T ype 100/300
and T ype 150/400 course computers. It provides the course computer
with precise information about the boat’ s yaw (its rate of turn). The
course computer uses this information to improve course keepin g:
• T ype 150/400 course comput ers: connecting the GyroPlus
enables nine response levels, provides enhanced course keeping
using AST (Advanced Steering T echnology). It also allo ws
access to AutoLearn (self-learning steering calibration) when
used with ST6001+ or ST7001+ control units.
• T ype 100/300 course comput ers: connecting the GyroPlus
enhances performance with the autopilot set to response level 3.
Autopilot operation in response levels 1 and 2 is unchanged.
