In addition to holding its course in a virtually all weather and wind conditions, the system can perform a variety of pre-programmed trolling and search procedures. Plus, with a compatible Garmin network chartplotter and BlueChart g2 Vision? charts, you gain optional features like Auto Guidance, which automatically createsGPS routes for the pilot to follow.

It works seamlessly with the Optimus 360?s revolutionary joystick steering/shift/throttle control system to negotiate the boat forward, backwards, diagonally, sideways or on its axis.
