Hi Troutman, it is very very good. Holds right on it, only movement is current, wash or wind. What it tends to do is hold the nose on the position, plus or mins a metre at worst. It is a very good piece of tech, as I said it makes fishing one handed much easier. With the bigger flattie yesterday I was very close to a mooring bouy, this held me on the spot until I decided I wanted to reverse out and clear him of the bouy. I then recalled my position and it took me straight back to my mark, all whilst still casting and prospecting. Every now & then if the motor head has gone around the shaft a few times, it thinks about it and does a complete motor head reversal to unwind any coil wrap, I mean, how good is that?
