The tiller pilot ST 2000 Plus is completely sufficient for the use as I use the device. Since I am predominantly alone sailing the tiller pilot is not to think away when setting the sails and under the engine during doldrums. Even if I have to go below deck, I can rely on it to stay on course. Here, however, I take a ride out of the ship, so that in gusts of wind not too strong pressure on the system mechanics is exercised. Alone under sail and only at the starter battery, I would not let run the self-steering systems, because I can not estimate the power consumption yet. At least not for hours. The instructions are good, you just have to read and familiarize yourself. Important!! The tiller pilot has to be adjusted !!! 1. On which side is the system mounted? Bb.- or Stb.-side the device needs the info otherwise it will not work. 2. By default, the sensitivity is set to 4. I reduced this value to 3 to have less power consumption. But everyone has to adjust and try it out for themselves. All in all, a practical thing that helps to assist and ease the individual sailing maneuvers.
